Durostone® EPC 205
GFK-EP
Durostone® EPC 205 is a fiber-reinforced plastic, which has exceptionally high mechanical strength. The gain is achieved by glass roving fabric and the burning behavior is defined.
Characteristics
- High dielectric strength
- High mechanical strength
- Flame retardant
- High-pressure laminate
- Special epoxy (EP) resin matrix reinforced with an e-glass roving fabric
Industries
Semiconductor High and low temperature
