Hardness Acrylic sheet hardness is one of the important parameters that can reflect the production process and technology, and it is also a part of quality control. The hardness can reflect the purity of the raw material MMA, the weather resistance of the plate, and the high temperature resistance.

ACRYLIC, a common name for the special treatment of organic glass. Acrylic research and development has a history of more than one hundred years. In 1872, the polymerization of acrylic acid was discovered; in 1880, the polymerization of methacrylic acid was known; the synthesis of propylene polyacry
