GPO-3 Board

GP0-3 board is made of alkali free glass fiber felt sheet immersed with unsaturated polyester resin add additive by hot press to form into hard sheet insulation. GPO-3 is a glass reinforced thermoset polyester sheet material. GPO-3 is strong, stiff, dimensionally stable, and impact resistant. The material also has excellent electrical properties including flame, arc, and track resistance.
