What is PMMA？

PMMA is commonly known as plexiglass, acrylic, etc. The chemical name of the polymer transparent material is polymethyl methacrylate, which is a polymer compound obtained by polymerizing methyl methacrylate. It is an important thermoplastic that was developed earlier. Plexiglass is divided into colorless and transparent, colored and transparent, pearlescent and embossed plexiglass. Plexiglass is commonly known as Acrylic, Zhongxuan Acrylic, and Acrylic. Plexiglass has good transparency, chemical stability, mechanical properties and weather resistance, easy dyeing, easy processing, and beautiful appearance. Plexiglass is also called gelatin glass, acrylic and so on.
The flow of PMMA is worse than that of PS and ABS. The melt viscosity is sensitive to temperature changes. In the molding process, the melt viscosity is changed mainly from the injection temperature. PMMA is an amorphous polymer with a melting temperature of more than 160 ° C and a decomposition temperature of 270 ° C.
