Product Description
This material is based on rubber type chlorinated polyethylene and mixed with flame retardant and anti-static additives. This product has good wear resistance, heat resistance, sun exposure resistance, acid and alkali resistance, oil resistance, and excellent flame retardancy, anti-static properties, etc. And the product has a major feature of no irritating odor during vulcanization.
Product Usage
The outer layer of XJG-SK rubber hose is the protective layer of the rubber hose, which is used for rubber hoses with flame retardant and anti-static requirements, such as high-pressure steel wire braided rubber hoses, automotive rubber hoses, fuel dispenser rubber hoses, etc. It is mainly used for rubber hoses in coal mines to prevent the generation of static sparks and underground fires.
