PMMA Resin(Polymethyl Methacrylate)
Introduction
PMMA resin is used methyl methacrylate (MMA) as major raw material to develop successfully. It has excellent weather-resist and heat-resist character, and excellent transparency and gloss. Besides, it has stable physical, chemical, optical, and electrical, etc., characters. It may be widely applied on electronic panel, mechanical parts, watch and clock shell, motorcycle and automobile indicator, tele-communication material, insulation parts and sun glasses, etc.
