How Much Do You Know About Acrylic?
The name acrylic comes from the English "acrylic" (acrylic plastic) and the chemical name is polymethyl methacrylate. Acrylic can also be called PMMA or plexiglass. It is an earlier developed thermoplastic. It has a history of more than 100 years. So far, acrylic is still the most excellent material in synthetic transparent materials. Let's take a look at pros of acrylic.
1. High light transmission
Acrylic's production process guarantees both transparency and pure whiteness. The light transmittance is up to 92%. The light is soft, the vision is clear and the light transmittance is higher than that of glass. The high light transmittance of acrylic is a highlight of acrylic sheet. And when we buy acrylic, the light transmittance is also one of the important indicators to measure acrylic. In general, we can use the Linshang light transmittance meter to test the light transmittance of acrylic sheet, so that we can better buy high quality acrylic sheet.
Light transmittance is an important technical indicator of many optical products, such as glass, window film, laminated glass, acrylic plate, etc. The test principle of the light transmittance meter : use a visible light source to illuminate the test substance. The sensor detects the incident light intensity of the light source and the light intensity after passing through the test substance. The ratio of the transmitted light intensity to the incident light intensity is transmitted, expressed as a percentage. The LS116 light transmittance meter uses a parallel light path design, which is suitable for detecting large thickness materials with an accuracy of within ± 1%.
2. High hardness
The relative molecular mass of acrylic is about 2 million. It is a long-chain polymer compound. The chain that forms the molecule is soft, so the acrylic strength is extremely high.
At the same time, hardness is also one of the important indicators to measure the quality of acrylic. The average hardness of high-quality acrylic plates can reach about 89 degrees rockwell hardness. Its tensile and impact resistance is 7-18 times higher than ordinary glass.
3. Easy to process
Acrylic has strong plasticity. It can be used for thermoforming or mechanical processing. Lathe cutting, drilling machine drilling, blow molding and other plastic molding methods can easily process acrylic into products of different sizes and functions.
At the same time, acrylic has good adaptability and sprayability. Using appropriate printing spraying technology can make acrylic products achieve the ideal surface decoration effect.
4. Light weight
Compared with ordinary glass, acrylic with the same volume weighs only half of ordinary glass; compared with metallic aluminum (light metal), it weighs only 43% of metallic aluminum. The lighter weight also makes acrylic easier to transport. The emergence of acrylic has made it possible for more high-quality products to appear.
