Product Description

Big size of GPO-3(UPGM203) sheet with UL and Reach&RoHs certificates meets Arc resistance 183 seconds

 

GPO3(UPGM203) also named glass fiber mat sheet or polyester resin sheet .

Polyester sheet is a stratified insulator made from fibre glass blanket and polyester resin. With very low hygrometric susceptibility, small losses at high frequency, excellent mechanical properties, good dielectric properties, V-0 flame resistance.

 

This material has certified by ROHS/REACH for meeting environmental requirements .

In order to meet the requirement for exporting to Europe and North America , the material have certificates of UL.

Feature of GPO-3

 

It has nice property on

(1) It is the advance retardant ,anti-impact and anti corrosion material in these recent years

(2) Arc resistence could reach more than 180S

(3) Good electronic performance under high temperature,good performance for anti leakage of electronic

(4) flame-retardant grade could reach 94-V0, thermal endurance class could reach F grade

(5) It is the advance retardant ,anti-impact and anti corrosion material in these recent years
