1. Hardness:

Hardness is one of the parameters that best reflect the production process and technology of cast acrylic panels, and is an important part of quality control. hard

The degree can reflect the purity of raw material PMMA, the weather resistance of the board, and the high temperature resistance. The hardness directly affects whether the board will shrink, bend or deform, and whether the surface will crack during processing. Hardness is one of the hardness indicators for evaluating the quality of acrylic boards, with an average Darrell hardness value of around 89 degrees.

2. Thickness tolerance:

The control of thickness tolerance of sheet metal is an important manifestation of quality management and production technology. The production of acrylic has an international standard ISO7823

Tolerance requirements for pouring plates: tolerance=± (0.4+0.1 x thickness)

Tolerance requirements for extruded boards: 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. After flame polishing, it becomes crystal clear.
