Halogen Free FR4 Epoxy Fiberglass Laminated Sheet(EPGC310)
Product Instruction
Halogen free FR4 is similar to FR4,but with halogen free compund.This product was laminated by the high temperature and high pressure with electronic glassfiber cloth impregnated with Halogen free epoxy resin.It with high mechanical properties,dielectric properties and flame retardant properties,it also with good heat resistance and moisture resistance;
Compliance with standards
In accordance with GB/T 1303.4-2009 electrical thermoset resin industrial hard laminates - Part 4: epoxy resin hard laminates, IEC 60893-3-2-2011 insulating materials - electrical thermoset resin industrial hard laminates - Part 3-2 of the individual material specification EPGC310.
Application
This product is mainly used as the halogen free required structure parts for Motor and electrical equipment,including all kinds of switch、electric equipment、FPC reinforcement plate、carbon film printed circuit boards、computer drilling pad、mould and smelting equipment(PCB test flame）;and also suitable under wet environment and transformer oil.
