1. Hardness:
Hardness is one of the parameters that best reflects the production process and technology of cast acrylic panels, and is an important part of quality control. hard
Degree can reflect the purity of raw material PMMA, the weather resistance and high temperature resistance of the board. Hardness directly affects whether the board will shrink, bend or deform, and whether there will be surface cracks during processing. Hardness is one of the hardness indicators for evaluating the quality of acrylic panels, with an average Dalloway hardness value of around 89 degrees.
