The materials often used in the production process of high-pressure hoses include nitrile rubber, styrene-butadiene rubber, neoprene, etc. With the advancement of technology and the development of the rubber industry. EPDM rubber, chlorosulfonated polyethylene, chloroether rubber, hydrogenated nitrile rubber, etc. are gradually applied to the products of high-pressure hose manufacturers. Used to manufacture high-performance, high-value-added high-pressure hose products. Reinforcement materials include nylon and polyester fiber. With the development of the textile industry, high-performance materials such as aramid fiber are gradually used in high-pressure hoses. (1) EPDM rubber: It has excellent heat resistance, steam resistance, weather aging resistance, chemical corrosion and excellent electrical insulation performance, especially good resistance to glycol ether brake fluid and vegetable oil. It is suitable for the manufacture of high-pressure hoses resistant to heat, steam and strong corrosive media. (2) Chlorosulfonated polyethylene rubber: it has excellent anti-ozone and weather aging properties. Good chemical corrosion resistance, excellent flame resistance, oil resistance and tear resistance. It is suitable for the manufacture of high-pressure rubber hoses that are resistant to strong corrosive media, flame resistance, and ozone aging, and is especially suitable for the manufacture of rubber hose outer layers used in harsh atmospheric environments. (3) Chlorine ether rubber: it has excellent weather resistance. Good oil and solvent resistance. Good flame resistance and low air permeability, suitable for making oil-resistant, ozone-resistant, weather-resistant and low-air-permeable high-pressure hoses. (4) Hydrogenated nitrile rubber: It has excellent oil resistance, corrosion resistance, high and low temperature resistance, oxidation resistance, dynamic fatigue resistance, and ozone resistance. It is suitable for the manufacture of high-pressure hoses with special requirements such as oil resistance. (5) Aramid fiber: Aramid fiber has excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. Its strength is 7 times that of steel wire. The modulus is 2-3 times that of steel wire or glass fiber. The toughness is twice that of steel wire, and the quality is only about 1/5 of that of steel wire. It does not decompose or melt at a temperature of 450 ° C, and has good insulation and aging resistance. very long life cycle.
