What are the materials of the high-temperature rubber joint, which is the best, Xinli explained to you in detail: 1. Natural rubber 2. Ethylene-propylene rubber 3. Fluorine rubber
Natural rubber is mainly composed of rubber hydrocarbon (polyisoprene), containing a small amount of protein water, resinate, sugars and inorganic salts. It has high elasticity, high tensile strength, good tear resistance and electrical insulation, good wear and drought resistance, good processability, easy bonding with other materials, and is superior to most synthetic rubber in comprehensive properties. The disadvantages are poor oxygen and ozone resistance, easy aging and deterioration, poor oil and solvent resistance, low corrosion resistance to acid and alkali, and low heat resistance. Temperature range: about-60 ℃~ + 80 ℃. Natural rubber is ideal for tire, rubber shoes, hose, tape, wire and cable insulation and sheathing, as well as other common products. Especially suitable for manufacturing torsional vibration eliminator, engine shock absorber, machine support, rubber-metal suspension element, diaphragm, molded products.
Ethylene-propylene rubber (EPDM) is a copolymer of ethylene and propylene, which is generally divided into binary ethylene propylene rubber and ethylene propylene diene rubber. Its excellent features are ozone resistance, UV resistance, weather resistance and aging resistance. It ranks first in general rubber, electrical insulation, chemical resistance, impact elasticity is very good, and it has acid and alkali resistance, small specific gravity, which can be high filling fit. Heat resistance up to 150 ℃, resistance to polar solvent--ketone, ester, etc., but not resistant to fatty hydrocarbons and aromatic hydrocarbons. Other physical and mechanical properties slightly inferior to natural rubber but superior to styrene-butadiene rubber. The disadvantage is that self-viscosity and mutual viscosity are very poor, not easy to bond. The operating temperature range is about -50 ℃ ~ 150 ℃. It mainly used as chemical equipment Lining, wire and cable foreskin, steam hose, heat-resistant transport belt, automotive rubber products and other industrial products.
Fluorine rubber is an organic elastomer formed by copolymerization of fluorine monomer. Its acid and alkali resistance, oil resistance is the best in oil resistance rubber, radiation resistance, high vacuum resistance, electrical insulation, mechanical properties, chemical corrosion resistance, ozone resistance, atmospheric aging resistance are excellent. The disadvantages are poor processability, expensive cold resistance and low elastic air permeability. The temperature range is from 20 ℃ to 200 ℃. It mainly used in the defense industry, aircraft, rocket vacuum, high temperature, chemical corrosion resistant sealing materials, hose or other parts and automotive industry.
The above three kinds of rubber are materials that can withstand high temperature in the connection of pipes. Consumers can choose the appropriate rubber materials according to their own conditions.
