The EPDM lined fire hose is made by dual-vulcanization. It agglomerates the present up-to-date science technology of macromolecule chemical field. Besides all advantages of natural rubber lined fire hoses, EPDM lined ones have the unique advantages of rot resistance, circumnutate resistance, high pressure resistance and climate performance resistance. Also, it has longer life and better security. It is particularly suitable for petrol-chemical and cold areas.
