Products and Information
Attwater Group | GE308
Material Details
| Grade: | GE308. (Type: Glass Based Laminates - SRBG) |
|---|---|
| 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. |
| Specifications: | BSEN60893-3-2-EPGC308 (Which supersedes BS3953 EP7). The closest NEMA equivalent to this specification is NEMA G11+. |
| Body Colour: | Pale Green |
| Cover Colour: | Pale Green |
| Standard Finish: | Satin/Glossy |
| Size: | 1220 x 1220 Thickness Range: 0.4 - 100.0 † |
