Physical properties of PMMA

Polymethyl methacrylate contains polar methyl ester groups at the side of the main chain, and its electrical properties are not as good as non-polar plastics such as polyolefin and polystyrene.

Physical properties of PMMA,The polarity of the methyl ester group is not too great, and polymethyl methacrylate still has good dielectric and electrical insulation properties. It is worth pointing out that polymethyl methacrylate and even the entire acrylic plastics have excellent arc resistance. Under the action of an arc, the surface will not produce carbonized conductive paths and arc tracks. 20°C is a secondary transition temperature, which corresponds to the temperature at which the pendant methyl ester groups begin to move. Below 20°C, the pendant methyl ester groups are in a frozen state, and the electrical properties of the material will be improved compared to those above 20°C.
