Attwater Group | GE308

Material Details

Grade:GE308
Description: Epoxy Glass. Similar to B36 - elevated mechanicals at temp
Comments:This grade has been developed for applications where improved thermal stability at elevated temperatures is required. The laminate is capable of continuous operation at class 180 (H) temperatures. This performance has been achieved using specially developed resin systems which ensure high mechanical and electrical strength, excellent resistance to high temperature and good dimensional stability. Technolaque? GE308 offers this unique combination of properties at a competitive price.
