Product Description
High performance FR4 epoxy sheet with third party certification / IEC testing center certified EPGC202 sheet
High performance FR4 epoxy sheet with third party certification are made of woven glass cloth impregnated with epoxy thermosetting resin,laminated under high temperature and high pressure ,the woven glass cloth shall be alkali-free and treated by silane couple
Feature:
EPGC sheets(thermal class B-H),producer as per IEC60893-3-2,These sheets have excellent mechanical strength(the thermal state retension rate can reach over 50%)under medium temperature or the thermal state,as well as the stable electric properties(the insulation resistance after immersion reachers 10^12Ω)in high humidity condition .and also with higher voltage end urance /withstand voltage (over 35KV),parallel to laminated ,and they also have excellent flame retardant property.the sheets also passed the toxic and hazadous substance detection(RoHS Report)
