PMMA Resin(Polymethyl Methacrylate) 


1. 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. 


2. Advantages: 
Unparalleled Transparency and Luster 
Excellent Weather Resistance 
Unmatched Surface Hardness 
Excellent Electrical Resistance 
Superior Mechanical Property 
Harmless to Humans 

3. Application: 
PMMA is widely used for instruments panel of automobile industry, pharmaceutical industry and other daily-using articles. Specifically, for making optical instrument, illuminating lamp and synthetic glass.
