GPO-3/UPGM203 polyester laminate is a hard board insulation material which is made of alkali-free glass fiber felt infiltrates unsaturated polyester resin paste and add the corresponding additives by hot pressing. Its electrical performance is excellent in high humidity environment, it also has excellent mechanical performance at medium temperature, it enjoys the characteristics of fire resistance, arc resistance, electric leakage resistance, etc.
The grinding sheet is finished on the basis of the smooth sheet, which is more accurate in thickness tolerance.
The drafter of national standard, possess 6 patents;
Low water absorption (≤0.5%);
Excellent arc resistance (arc resistance ≥180 seconds);
Excellent electric leakage resistance (≥600V);
Excellent heat resistance (heat resistance grade reaches 155℃);
