fiberglass sleeving coated with silicone rubber

silicone rubber coated fiberglass braided sleeve thermal treatment good qualities of dielectric high temperature resist

Fiberglass sleeving coated with silicone rubber produced with the process of thermal treatment and vulcanization is the non alkali fiberglass braided sleeving coated with silicone rubber. this sleeving possess good qualities of dielectric, high temperature resistance, excellent elasticity and cold resistance. It can be used of wiring insulation and mechanical protection for H grade electrical applicances.

Note: the breakdown voltage for sleevings whose inner diameter is or below 1.5mm, should not than 75% of the specified voltage.
