With the advancement of technology and the development of the rubber industry, butadiene rubber, styrene-butadiene rubber, neoprene, etc. are often used in the production of high-pressure hoses. EPDM, chlorosulfonated polyethylene, chloroether rubber, and hydrogenated styrene-butadiene rubber are gradually used in the products of high-pressure hose manufacturers. It is used to manufacture high-performance, high-value-added high-pressure hose products. Reinforcement 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, weathering resistance, chemical corrosion resistance and excellent electrical insulation properties, especially glycol ether brake fluid and vegetable oil. It is suitable for making high-pressure hoses that are resistant to heat, steam and corrosive media.

(2) Chlorosulfonated polyethylene rubber: It has excellent ozone resistance and all-weather aging properties. Good chemical corrosion resistance, flame resistance, oil resistance and tear resistance. It is suitable for manufacturing high-pressure hoses that are resistant to corrosive media, flame resistance, and ozone aging resistance, and is especially suitable for manufacturing hose covers used in harsh weather environments.

(3) Chloroether rubber: It has excellent resistance and excellent performance. Oil and solvent resistance is good. Good flame resistance and low air permeability, suitable for the manufacture of oil-resistant, ozone-resistant, weather-resistant, low-air permeability high-pressure hoses.

(4) Hydrogenated butadiene rubber: oil resistance, corrosion resistance, high and low temperature resistance, oxidation resistance, dynamic fatigue resistance, ozone resistance. It is suitable for manufacturing 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, 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 450 °C, and has good insulation and aging resistance. Long life cycle.
