The hardness
Hardness is one of the parameters which can best reflect the production process and technology of casting acrylic sheet and is an important link in quality control. The hardness can reflect the purity of PMMA, the weatherability and high temperature resistance of the plate. Hardness directly affects whether the sheet will shrink, bend and deform, whether the surface will crack during processing and so on. Hardness is one of the hard indicators to judge the quality of acrylic board.
