Description:
With NBR or neoprene, it resists oil, good material as gasket, light and good compressed
It made from cork granule with NBR or neoprene, have good compressed cacacity, light weight and good chemical capacity.
Cork in electrical industry special cork and rubber had been developed to prevent leakage of the very searching cooling fluids used in modern electrical transformer, similar material are also widely used in switch gear circuit breakers, lighting arresters, and other transmission equipment, as well as in conduit fittings, gear cases and cover plates in washing machines.
Sealing material is compounded with Nitrite (NBR)rubber. This product is suitable for most transformer oils at application
