Key word:Characteristics and application of acrylic materials

Acrylic performance
1. With crystal-like transparency, light transmittance of more than 92%, soft light, clear vision, acrylic dyed with dye has a good color effect.
2. Acrylic sheet has excellent weather resistance, high surface hardness and surface gloss, and good high temperature performance.
3. Acrylic sheet has good processing properties, both thermoforming and mechanical processing.
4. Transparent acrylic sheet has a light transmittance comparable to that of glass.

3. Acrylic sheet has good processing properties, both thermoforming and mechanical processing.
4. Transparent acrylic sheet has a light transmittance comparable to glass, but the density is only half of the glass. In addition, it is not as fragile as glass, and even if it is destroyed, it does not form sharp fragments like glass.
5. The abrasion resistance of the acrylic sheet is close to that of aluminum, the stability is good, and it is resistant to corrosion by various chemicals.
6. Acrylic sheet has good printability and sprayability, using appropriate printing and spraying process, can give acrylic glass products the ideal surface decoration effect.
7. Flame resistance: It is not self-igniting but it is flammable and does not have self-extinguishing properties.

Acrylic characteristics
1. Hardness
Hardness is one of the parameters that best reflects the production process and technology of pouring acrylic sheet, and is an important part of quality control. The hardness can reflect the purity of the raw material PMMA, the weather resistance of the sheet, and the high temperature resistance. The hardness directly affects whether the sheet will shrink and bend, and whether the surface will be cracked during processing. Hardness is one of the hard and good indicators for judging the quality of acrylic sheets. The average Dalhou hardness value is about 8 or 9 degrees.


2. Thickness (acrylic tolerance)
Acrylic sheet thickness has acrylic tolerances, so the control of acrylic tolerance is an important manifestation of quality management and production technology. Acrylic production has an international standard ISO7823, tolerance requirements for cast-in-place plates: tolerance = ± (0.4 + 0.1 x thickness), tolerance requirements for extruded plates: tolerance = < 3 mm thickness: ± 10 % > 3 mm thickness: ± 5 %.


3. Transparency / whiteness
Strict raw material selection, advanced formulation follow-up and modern production processes ensure excellent transparency and whiteness. After the flame is polished, it is crystal clear.

Use of acrylic
1. Acrylic products include acrylic sheet, acrylic plastic pellet, acrylic light box, signboard, acrylic bathtub, acrylic artificial marble, acrylic resin, acrylic (latex) paint, acrylic adhesive and so on.
2. Acrylic products commonly used by people are made of acrylic pellets, plates or resins and other raw materials, and assembled with various materials and functional parts to make acrylic products. Acrylic fiber, acrylic cotton, acrylic yarn, acrylic nylon, etc., which are commonly heard, are man-made fibers polymerized from acrylic acid and are not associated with acrylic products.
3. Among them, the acrylic sheet is often referred to as polymethyl methacrylate Polymeric Methyl Methacrylate (PMMA) sheet, which is made of "methyl methacrylate monomer Methyl Methacrylate (MMA)". Or extruded from acrylic pellets through a extruder. In the past, the plate was called plexiglass. Acrylic is derived from English acrylic, meaning PMMA board made of organic compound MMA, which has transparency and transparency like glass. Plates derived from all transparent plastics such as PS, PC, etc. or from inferior recycled MMA are collectively referred to as plexiglass. In order to distinguish, the PMMA board made of high quality pure material MMA is named as acrylic sheet to distinguish it from ordinary plexiglass board.
