Physical Properties Of PMMA Acrylic Sheet

PMMA Acrylic Sheet is actually a treated plexiglass. It can be said to be a substitute for solid color, rich color and plexiglass. Acrylic light box has good light transmission and beautiful appearance. Both day and night effects can be used. Taken into account, because the service life is also quite long, other perfect combinations to meet all needs.

PMMA Acrylic Sheet has excellent overall mechanical properties. At the forefront of general plastics, tensile, bending, compression and other strengths are higher than polyolefin, polystyrene, higher than polyvinyl chloride, but not only poor impact toughness, slightly more than polystyrene. Ethylene is better. PMMA Acrylic Sheet has a low surface hardness and is easily scratched. Although the heat resistance is not high, the glass transition temperature reaches 104 ° C, but the continuous working temperature depends on the working conditions of 65 ° c - 95 ° c, the heat distortion temperature is about 96 ° C (1.18 MPa), and the cam softening point is 113. The size of about °C, by copolymerization of acrylic acrylate or expanded ethylene glycol monomer, can improve heat resistance.
