GPO3 Glass Fiber Coated Polyester Resin Sheet With Low Water Absortion


Red GPO3 Glass fiber coated polyester resin plate have high flexture strength and low water absortion



Glass fiber coated polyester resin plate is a glass reinforced thermoset polyester sheet material.

This material has excellent electric/ mechanical properties , it is strong, dimensionally stable and impact resistant of mechanical properties. The material also has good properties on flame, arc and track resistance.



with very low water absorption , it is only 0.0048% of water absorption .
It has very excellent machining properties such as the tolerance will be meeting ISO2768-F class

Very stable of the strength when the continue working temperature reach 155℃ (F Class)
