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. It is used to manufacture high-performance, high-value-added high-pressure hose products. Reinforcing materials include nylon and polyester fibers. With the development of the textile industry, high-performance materials such as aramid fibers are gradually used in high-pressure hoses.
(1) EPDM rubber: It has excellent heat resistance, steam resistance, weather resistance, chemical corrosion and excellent electrical insulation properties, especially good resistance to glycol ether brake fluid and vegetable oil. It is suitable for the manufacture of high-pressure hoses that are resistant to heat, steam and strong corrosive media.
(2) Chlorosulfonated polyethylene rubber: It has excellent anti-ozone and weathering properties. Good chemical resistance, excellent flame resistance, oil resistance and tear resistance. It is suitable for the manufacture of high-pressure hoses that are resistant to strong corrosive media, flame resistance, and ozone aging resistance, and is especially suitable for the manufacture of outer rubber hoses used in harsh atmospheric environments.
(3) Chloroether rubber: has excellent weathering resistance. Good oil and solvent resistance. Good flame resistance and low air permeability, suitable for the manufacture of oil-resistant, ozone-resistant, weather-resistant and low-air permeability high-pressure hoses.
(4) Hydrogenated nitrile 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, and 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 anti-aging properties. very long life cycle.
