What are the characteristics of acrylic sheet

- May 10, 2020-

Acrylic production has an international standard ISO7823 Tolerance requirements for cast plates: tolerance = ± (0.4 + 0.1 x thickness) Tolerance requirements for extruded plates: tolerance = 3 mm thickness: ± 5% 3. Transparency / whiteness: strict Raw material matching and selection, advanced formula follow-up and modern production process production ensure excellent transparency and pure whiteness of the board. Crystal clear after flame polishing.

1. Thickness acrylic tolerance: There is acrylic tolerance for the thickness of acrylic sheet, so the control of acrylic tolerance is an important manifestation of quality management and production technology.

2. Hardness: Hardness is one of the parameters that can best reflect the production process and technology of cast 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 plate and the high temperature resistance.

The hardness directly affects whether the sheet will shrink and bend, and whether the surface will crack or the like during processing. Hardness is one of the indicators to judge the quality of acrylic plates. The average Dalough hardness value is about 89 degrees
