Acrylic properties
1. It has crystal-like transparency, the light transmittance is above 92%, the light is soft, the vision is clear, and the acrylic colored with dyes has a good color development 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 performance, which can be thermoformed or mechanically processed.
4. The transparent acrylic sheet has a light transmittance comparable to that of glass, but the density is only half of that of glass. In addition, it is not as brittle as glass, and even if broken, it will not form sharp shards like glass.
5. The wear resistance of acrylic sheet is close to that of aluminum, with good stability and corrosion resistance to various chemicals.
6. Acrylic sheets have good printability and sprayability. By using appropriate printing and spraying processes, acrylic products can be given an ideal surface decoration effect.
7. Flame resistance: It is not self-igniting but belongs to flammable products, and does not have self-extinguishing properties.
Acrylic Features
1. Hardness
Hardness is one of the parameters that can best reflect the production process and technology of cast acrylic sheets, and it 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 plate will shrink and bend, and whether the surface will crack during processing. Hardness is one of the hardness indicators for judging the quality of acrylic sheets, and the average Da Rockwell hardness value is about 8 or 9 degrees.
2. Thickness (Acrylic tolerance)
Acrylic sheet thickness has acrylic tolerance, 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 the cast plate: Tolerance = ± (0.4 + 0.1 x thickness)
Tolerance requirements for extruded sheet: Tolerance=< 3 mm Thickness: ± 10 %> 3 mm Thickness: ± 5 %
3. Transparency/whiteness
Strict raw material selection, advanced formula follow-up and modern production technology ensure excellent transparency and pure whiteness of the board. Crystal clear after flame polishing.
