Description


Epoxy fiberglass laminated sheet is a layered material obtained by hot pressing two or more layers of glass fabric of alkali-free glass (with a continuous thread), impregnated with thermosetting resins on a phenolic or epoxy basis. Also called epoxy glass sheet, the epoxy fiberglass sheets have excellent electrical insulation and mechanical properties. Epoxy fiberglass laminated sheet is non-toxic, non-explosive and non-flammable. Due to the glass fabric, epoxy sheets have a higher modulus of elasticity, strength and wear resistance compared to materials such as phenolic cotton cloth laminated sheet, phenolic paper sheet and some technical plastics.
