Heat resistant G10 FR4 glass epoxy sheet

These G-10/FR4 sheets are strong, machinable, and electrically insulating. They're made of a flame-retardant epoxy resin with fiberglass fabric reinforcement. G-10/FR4 is also called epoxy-grade industrial laminate and phenolic.



G-10/FR-4 is a thermosetting industrial laminate consisting of a continuous filament glass cloth 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 conditions.


The product has the following characteristics:

Color: Green,Black and customized is available
Thickness: 0.3~100mm
Standard Sheet Sizes: 1020x1220mm,1020x2040mm,1220x2470mm
Max. Temperature: 265° F
Tensile Strength: 35,000-50,000 psi (Excellent)
Impact Strength: 5.5-12 ft.-lbs./in. (Excellent)
