UL recognized GPO-3 (UPGM203) glass fiber laminated sheet application for electrical industry
Product Introduction:
GPO-3 laminated sheet is composite material which made of glass fiber and polyester resin . GPO-3 is also known as UPGM203 , they are the
Same material but from different standard .
GPO-3 composite material which we can supplying include laminated sheet/molded parts/Pultrusion shape ;
a.Laminated sheet
size of laminated sheet as following :
Thickness from 0.5-3mm , length and width of sheet is 1200x1000mm ; thickness≥4mm , length and width is 2100x1230mm;
Color : red and white
Type of sheet : normal sheet and grinded sheet
b. molded part and /Pultrusion shape
These material should be produced by mold , if the size from customers not in specification , it should be develop the mold .
GPO-3 material as the excellent insulation material on electrical and mechanical properties , it has been more and more widely used in electrical
Industry .
Feature of GPO-3
1. It has very nice Comparative Tracking Index , the CTI≥ 600V
2. Meet requirement of UL94 V-0 fire resistance
3. It is halogen-free material
4. Excellent heat resistance ,it is F Class
5. Excellent arc resistance ,it can meet 184 second
6. ROHS and REACH certified once a year
