What are the characteristics of Acrylic Round Rod?

Hardness is one of the parameters that best reflects the production process and technology of cast acrylic sheets, and 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 hard indicators to judge the quality of Acrylic Round Rod.
