1.Characteristic
and usage
The product based on phenolic resin with glassfibre
and mineral filler and other additives is processed into thermosetting
plastics. It is suitable for injection process. Injection best transfers
better. It has better property of mechanics and electric insulation, meanwhile
possess of better resistance heat and resistance water and flame resistance
and resistance leakage of electricity and dimensional stability. It is
mainly used for making insulating structures which have resistance heat
and resistance impact. The product appearance is the blends of power and
granules.
