High Quality Epoxy Fiberglass Sheet G11 Material
High Quality Epoxy Fiberglass Sheet G11 Material
G11 sheet is a kind of laminated sheet formed through heat pressing after the electric industry fiberglass cloth dips into epoxy resin.Suitable as the mechanical, electric and electronic insulation structural components which are used under homoeothermy and middle temperatures with a certain mechanical performance and electric performance.
This product is made of glass fiber cloth for electronics impregnated with brominated epoxy resin and heated and pressurized. It has high mechanical properties, dielectric properties and flame retardant properties, good heat resistance and moisture resistance, and good machinability;It fully meets the requirements of EU RHOS standards and SGS standards, and is widely exported to Southeast Asia, the EU, India and other regions.It is widely used in products which requiring high-performance electronic insulation, such as FPC reinforcement boards, PCB drilling pads, glass fiber mesons, potentiometer carbon film printed glass fiber boards, precision star gears (wafer grinding), precision test plates, Electrical (electrical) equipment insulation stay spacers, insulation backing plates, transformer insulation plates, motor insulation parts, grinding gears, electronic switch insulation plates, etc.
