Product Description

High strength insulation laminate FR4 G10 epoxy glass sheet

High strength insulation laminate FR4 G10 epoxy glass sheet is a thermosetting industrial laminate consisting of a continuous filament glass fiber material with an epoxy resin binder. It has characteristics of high strength, excellent electrical properties and chemical resistance not only at room temperature but also under humid or moist condition. The different between FR4 and G10 is  that FR4 has the flame retardant property which meets the UL94 V-0 standard. The most versatile all around laminate grades are continuous glass woven fabric impregnated with an epoxy resin binder. Epoxy resins are among the most versatile and widely used plastics in the electronics field, primarily because water absorption is virtually nil, rendering it an outstanding insulator.
