Product Introduction
Production Description
Glass epoxy sheet is epoxy glass fiber cloth laminate which is a laminated product made of chemically treated electrical alkali-free glass fiber cloth as the base and epoxy resin as the binder with phenolic resin as curing agent. The Key Features and Benefits are the material has high dielectric strength, radiation resistant, high tensile strength, chemically resistant, dimensional stability, low dissipation factor and high impact strength
Application
Electrical Material 3240 Epoxy Fiberglass Resin Board is an important part in many industries such as machinery industry, electrical industry, electronics industry and etc. It could be used as PCB drilling pad, distribution box, fixture board, mold splint, high and low voltage wiring box.
