What is Acrylic
1. "Acrylic" acrylic word may sound very strange, because it was nearly two years before the emergence of a new type of words in the continent. Until 2002, its advertising industry, furniture industry, handicraft industry will gradually understand a few people. "Acrylic" is a transliteration of foreign words in English are ACRYLIC, it is a chemical material. The chemical name is called "PMMA" belong propylene glycols, commonly known as "specially treated glass", it is generally in the form of particulate material, sheet, pipe and other industries in the application.
2. The acrylic plate and glass "glass" from the English Organic Glass. In some areas in recent years all made of transparent plastic sheet are collectively referred to as plexiglass, in fact, this is wrong, specifically refers to pure acrylic polymethyl methacrylate (PMMA) materials, PMMA sheet and put acrylic sheet .
3. The characteristics and advantages of acrylic acrylic sheet with high transparency, light transmission rate of 92%, the "plastic crystal" reputation. And have excellent weather resistance, especially applied to outdoor, ranking the highest in other plastics, and both a good surface hardness and gloss, processing plasticity, can be made into a variety of shapes and products needed. Another sheet of a wide variety of rich colors (including semi-transparent color palette), and the other is characterized by thick and still maintain a high level of transparency.

Acrylic Introduction
Acrylic known by the English transliteration from Acrylics Acrylics acrylic and methacrylic chemicals. Include monomers, plates, pellets, resins and composites, acrylic sheet by methyl enoic acid methyl ester monomer (MMA) polymerization, i.e., polymethyl methacrylate (PMMA) sheet plexiglass, "Organic glass "from the trade name" Oroglas "(one kind of PMMA board), taken from the" Organic Glass "(ie PMMA). But in recent years because of all the clear plastic such as PS, PC etc. collectively plexiglass.
Acrylic production process
Acrylic sheet production process can be divided according to type cast and extruded, cast-type sheet extruded better performance than the price should be more expensive, type of sheet metal is mainly used for casting sculpture, decoration, crafts, squeeze pressure type usually used for advertising signs, light boxes and other production.

Acrylic uses
PMMA with light, inexpensive, easy to shape and so on. It has a cast molding method, injection molding, machining, hot forming. Especially in injection molding, can be mass-produced, the process is simple, low cost. Therefore, its increasingly widespread application, now it is widely used in instrument parts, car lights, optical lenses, transparent pipes.
Acrylic is the second ceramic sanitary ware capable of producing the best new material. Compared with conventional ceramic materials, in addition to unparalleled high bright acrylic givers, as well as the following advantages: good toughness, not damaged; repair and strong, just use soft foam dipped in toothpaste can be a new sanitary wipe; soft texture, winter no sense of bone-chilling cold; colorful, can meet the different tastes of individual pursuit. With acrylic basin, bathtub, toilet, not only exquisite style, durable, and has environmental effects, the extent of radiation line with the body's own bone is almost the same. Acrylic ware first appeared in the United States, now accounting for more than 70% of the international market.
Acrylic difficult to produce due to the high cost, so there is a lot of low-quality inexpensive substitutes on the market. These substitutes also known as "acrylic" is actually common organic board or composite board (also known as sandwich panels). Plexiglass plate with ordinary common organic material plus pigment cracking casting, low surface hardness, easy to fade, poor results after polishing polished with fine sand. Only the surface of a thin layer of composite panels of acrylic, the middle is ABS plastic, easy to use, affected by the expansion and contraction of delamination. True and false acrylic, can go from subtle color recognition and polishing section of the plate

Acrylic you know how many?
"Acrylic" Acrylics English transliteration, it is known as acrylic chemicals. In the field of plastics, acrylic poly methyl That means PMMA, is a kind of integrated performance engineering thermoplastics.
1872 acrylic polymerization of undiscovered; 1880 methacrylic polymerizable become known; polylactic acid 1901 study lipid synthesis is completed; in 1927 the use of the aforementioned synthesis try industrialized manufacturing; 1937 methacrylate industrial manufacturing successful development, thereby entering the scale manufacture. During World War II because acrylic has excellent strength and toughness and transparency, the first to be used in aircraft windscreen, tanks cab driver vision mirror. 1948 birth of the world's first acrylic bathtub, marking the acrylic application into a new milestone. Into the sixties, acrylic widely used in civilian products.
Acrylic The most prominent feature is crystal clear, the transmittance of 92%, which is the most of the plastic material. All plastic or acrylic ultraviolet (UV) most insensitive, this polycarbonate (ie PC) in stark contrast. Acrylic is also very susceptible to oxidation, weathering strong. Thus, after extended use, acrylic remains high transparency and transmittance. Other features acrylic does not have a high surface gloss, good surface hardness (with copper and aluminum equivalent), easy to process (including thermoforming and machining), chemical resistance and dimensional stability (not easily deformed) and so on. Above features make acrylic has been widely used.
Mostly in the form of acrylic sheet inside for outdoor and outdoor signs. Acrylic sheet production process by casting plate and extrusion plate divided by product performance can be divided into a transparent plate (including dyeing plate transparent plate) and Swatch (including black and white and color plates), ordinary plates and special plates such as high impact plates, matte board, metallic effects boards, high wear plates, fire-retardant board, light guide, etc. Program is widely used in all kinds of acrylic board signs in the field, this is because the material characteristics of acrylic great to meet the performance requirements of signs, including light, durable, beautiful and varied, as well as a variety of colors and surface effects and so on.
Characteristics of acrylic sheet and its application in the market
Acrylic sheet production process by casting plate and extrusion plate divided into two categories.
Cast acrylic board
High molecular weight, excellent stiffness, strength and excellent chemical resistance. This feature is a small batch processing sheet has unmatched flexibility in color and surface texture effect of the system, and the product specifications for a variety of special purpose.
Acrylic Extrusion board
Compared with the casting plate, the lower extrusion plate molecular weight, mechanical properties weaker. However, this feature is conducive to bending and thermoforming process, in dealing with the larger size of the plate, is conducive to fast plastic vacuum forming. Meanwhile, out of the plate thickness tolerances smaller than the cast plate. Because crowded board is a high volume automated production, adjust color and size of inconvenience, so the diversity of product specifications are subject to certain restrictions.
Over the years, thermoformed acrylic sheet has been one of the most creative use. With improvements in process technology and product variety, rich sound performance, relative to other traditional materials advertising signs, acrylic processing more convenient, cost-effective security products are also more reasonable.
Features and advantages of the acrylic sheet
Unparalleled outdoor durability
· Transparent plate such as crystal clear
Surface high gloss, smooth
· Complete product line, there are a variety of colors transparent, translucent, white, etc., and various surface effects
Excellent processability; thermoforming production visual effects prominent signs, when identifying the process is simple, reasonable cost
· Green environmental protection, waste material can be completely recycled, recycling easy
· Excellent surface hardness and scratch resistance
· Good chemical resistance, superior to most other plastic materials
· Easy to clean, maintain and ensure signs, light boxes, such as the appearance of new perennial
The difference between the merits of acrylic plates and simple identification methods
Acrylic sheet is also good or bad, on the country's current domestic pressure gram sheet market, there is an inexpensive, low-quality acrylic sheet - Recycling acrylic panels. Such plates, acrylic scrap is recycled, after the thermal degradation is regenerated MMA (methyl methacrylate) monomer, and then after the polymerization by chemical reaction obtained. Need to specify that, in a foreign country, acrylic manufacturers to develop a scientific waste recycling program, and has invested heavily in waste pyrolysis plant, after a rigorous process, you can retrieve the pure MMA monomer, and newly synthesized single body, the quality does not make any difference. And now some of the technology behind the country's small factory workshops, because of one-sided pursuit of profit, the production of the poor condition of the degradation of the monomer to produce, purity is not high, made of sheet metal after its quality tends to be commended.
Pure new material transparent acrylic plate
Excellent UV resistance, outdoor 10-year-yellowing, will not fade, loss of light, no cracking
Light transmittance greater than 92%, colorless transparent cross-sectional spot
High surface hardness, and aluminum and brass fairly
Excellent resistance to cracking and chemical resistance
High quality protective film to provide adequate protection
Back to the material transparent acrylic plate
UV resistance is very poor, up to six months will yellowing, prone to crack under the sunlight
Transmittance of less than 86%, the section of the yellow
Low surface hardness, easy to scratch
Easy to crack
Protective film of poor quality, easy to aging deterioration
This easy to identify by this method, you can easily identify the acrylic sheet quality is good or bad, to avoid unnecessary losses.
Because people do not understand the regeneration of acrylic sheet and its low price, recycled acrylic panels in the domestic market also occupy a lot of space. It can be expected that, as people gradually in-depth understanding of the acrylic material, recycled board living space will become smaller and smaller.
Long-term performance
Like with all plastic material, impact resistance acrylic products will increase as temperature decreases weakened. High-quality acrylic board, usually made of high quality materials and unique formula production process, it has excellent long-term outdoor use performance, light boxes, signs applications, expected outdoor life of more than 10 years.
Acrylic Product Performance
Weatherability
Acrylic sheet with excellent outdoor durability, can be Qiao is the best of all plastic materials. Under normal outdoor conditions of use, design, and reasonable processing acrylic board signs, after 10 years of use, it will not reduce its mechanical strength, appearance will not change significantly.
Swatches of light transmission properties
High-quality acrylic panels will produce according to strict quality standards to ensure that different batches, different plates have the same color. Because color swatches along the entire sheet thickness direction evenly distributed, so the worn surface is anti-brand exterior colors will have some impact when lighting.
Most acrylic swatches transmittance with increasing thickness of the sheet will be reduced, for the application of certain aspects of identity, this effect could have adverse effects - for example, to use both at the same logo swatches of different thickness , there will be obvious color. In this case, you can consider using some fixed transmittance acrylic color swatches, although plate thickness together, but show the same color light transmission.
Acrylic sheet and advertising signs
Whether you want the world to establish a unified symbol of multinationals or small shops, factories, offices, we need to have a durable, eye-catching, unique and economical signs. Acrylic sheet excellent performance can fully meet the above requirements, even and soft translucent acrylic boxes and distinctive, and therefore not only eye-catching but also energy saving; its glossy acrylic acrylic light box signage makes no lights in the daytime under the conditions are particularly noticeable, and ease of processing, selecting the appropriate species and processing methods can produce a wide variety of light boxes or signs. Durable acrylic boxes, available in more than a decade in the outdoors, installation and maintenance is also very convenient. Acrylic Light Box Signs For regular cleaning, the method is very simple, with soapy water and a soft cloth or brush to scrub, but not with a stiff brush or coarse, To improve the degree of static light boxes, special anti-static spray agent effect is remarkable.
You may have noticed that McDonald's restaurants around the world are using the uniform color and shape acrylic signs; BP company selected unique decorative green and yellow acrylic signs global gas station; the famous department store chain stores Marks & Spencer (Marks seeking Spencer) using translucent acrylic panels with different degrees more than 400 stores in Europe and Asia fitted with a bright eye-catching signs.
Widely used in acrylic
Acrylic has a transparent, lightweight, weather resistant, easy to shape and so on. It has a cast molding method, injection molding, machining, hot forming. In particular, injection molding, the injection mold can be mass-produced, the process is simple, low cost. In recent years, equipment and processing technology continues to improve, the quality and quantity of acrylic products, increase with age range of applications are becoming increasingly widespread, especially in the advancement of technology, acrylic has become the liquid crystal display (LCD) of the photoconductive material.

Characteristics of acrylic plexiglass
High transparency
PMMA is the most excellent of transparent polymer material, the light transmittance of 92%, high light transmission than glass. Small artificial sun called the sun lights the lamp is made of quartz, because quartz completely through the UV. Ordinary glass only 0.6% of the UV through, but was able through the plexiglass 73%.
High mechanical strength
Plexiglass relative molecular mass of about 200 million, is a long-chain polymers, and the formation of molecular chains is very soft, so the strength of PMMA is relatively high, the ability of high tensile and impact than ordinary glass 7 ~ 18 times. There is a heated and stretched-treated glass, in which the molecular chains arranged very orderly, so that the toughness of the material are significantly improved. With a nail into this glass, even nails penetrated, no cracks on the plexiglass. This plexiglass after a bullet penetrated the same will not break into pieces. Therefore, stretching plexiglass used as bulletproof glass processing, also used on military aircraft cockpit cover.
Light weight
Plexiglass density of 1.18 --- 1.19kg / dm3, the same size of the material, only half the weight of ordinary glass, aluminum (of a light metal) of 43%.
Easy processing
Not only can plexiglass cutting lathe, drill press to drill, and can use acetone, chloroform and other appliances bonded into various shapes and plexiglass products, also can be used blow molding, injection molding of plastic extrusion processing methods National Cheng Kung University to cockpit cover, small to dentures and denture kinds of products.
Acrylic crafts items
A heat distortion temperature of ordinary acrylic plate is about 100 degrees, continuous use temperature is not above 90 degrees.
2, acrylic plate surface hardness equivalent to aluminum, use or processing should be careful to avoid the surface is scratched. If they are scratched, you can restore the original luster by polishing the surface.
3, acrylic plate prone to static electricity, dust absorption. Dipped 1% soapy cleaning wipe with a soft cloth.
4, acrylic casting plate has a certain coefficient of expansion, when installing acrylic panels must leave enough to be considered an appropriate expansion gap.
How to avoid deformation of acrylic products
1, the mounting frame must be reserved for the contraction and expansion of the gap
2, to be drilled with the screw holes on oval lock
3, the choice of an elastic rubber gasket
4, thermoforming can improve impact strength, and the release of internal stress
6, thermoformed into a wavy, diamond-type and semi-circular acrylic panels to prevent sagging deformation due to weight
6, when using large-format acrylic board, need to increase the thickness of the plate to prevent deformation due to its own weight sag
7. Select the appropriate thickness to avoid wind loads resulting acrylic plate bending
Plexiglass market development prospects
Plexiglass is an important early development of thermoplastics, with transparency, stability and weather resistance, easy to stain, easy processing, beautiful appearance, has been widely used in the construction industry.
In the construction industry, mainly used in lighting plexiglass body, roof, roof, stairs and interior wall plates, and so on. In recent years, glass used in lighting and advanced shade highway roads and automotive lighting aspect is quite fast. With the construction of big city restaurants, hotels and high-end residential and light body is developing rapidly, the use of light body made of plexiglass plate with a high overall structural strength, light weight, high transmittance and good safety performance characteristics, and compared to inorganic glass lighting devices, has great advantages.
In sanitary ware, glass can produce a bathtub, washbasin, dressing table and other products. Because of plexiglass bath with the appearance of luxury, deep feeling, easy to clean, high strength, light weight and comfortable to use and other characteristics, has been widely used in recent years.
