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
Introduction:
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.
Feature:
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)
