1.  Features: 
1) High light transmission: Up to 88% that of same thickness of general glass. 
2) Excellent impact resistance: 80 times that of glass. 
3) Weather and UV resistant: Properties retained for years.: Temperature resistance range is -40º C ~ +120º C, with an ultraviolet coextruded film on the sheet surface. It can prevent the resin fatigue or yellowing caused by the ultraviolet. 
4) Light weight: Only 1/12 of the weight of glass of the same thickness. It can be easily cold bent as well as thermal shaping. 
5) Flame resistance: High fire performance rating is class B1. 
6) Sound and heat insulation: Superb sound insulation for freeway barrier and super thermal insulation save energy. 
7) An engineering plastic of excellent integration capability. It has outstanding physical, mechanical, electrical and heat capabilities.
