EPGC204 Epoxy Fiberglass Laminated Sheet(FR5)
Product Instruction
This product was laminated by the high temperature and high pressure with electrician used alkali free glass fiber cloth impregnated with special epoxy resin,it belongs grade F heat resistance insulation material.It has high mechanical properties under medium temperature,and stable electrical performance under high temperature .It is suitable used in mechanical,electrical and electronic as the high insulation components.It has high mechanical strength,thermal state mechanical strength,fire resistance,heat resistance and humidity resistance.It is match to NEMA FR5.
Compliance with standards
In accordance with GB/T 1303.4-2009 electrical thermosetting resin industrial hard laminates - Part 4: epoxy resin hard laminates, IEC 60893-3-2-2011 insulating materials - electrical thermosetting resin industrial hard laminates - Part 3-2 of the individual material specification EPGC204.
Application
Used for mechanical, electrical, electrical equipment as insulation components, and used in transformer oil and wet environment.
EPGC204 compare to EPGC202,the TG is higher,the thermostablity is grade F (155 degree),our EPGC204 has passed the test of EN45545-2:2013+A1:2015: Railway applications - Fire protection of railway vehicles-Part2:Requirement for fire behaviour of materials and components.and be approved by CRRC, we start to supply EPGC204 to CRRC from 2020. If you have any questions please contact us.
