G11R Epoxy Fiberglass Laminated Sheet(EPGC205)
Product Instruction
EPGC205/Roving reinforced G11R material are continuous filament woven fiberglass sheets bonded with high temperature epoxy resin. EPGC205/G11R is similar to type EPGC203/G11R,but with roving cloth.The material has the ability to maintain excellent mechanical,electrical and physical properties at elevated temperature to 155℃.
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 EPGC205.
Application
Mostly used in electrical machines and equipments as slot-wedges, fillers, cover plates, nut insulation, inter mediates, distances, etc.
