Natural rubber (NR) is mainly rubber hydrocarbon (polyisoprene), containing a small amount of protein, water, resin acid, sugars and inorganic salts. Large elasticity, high tensile strength, excellent tear resistance and electrical insulation, good wear resistance and drought resistance, good processability, easy to bond with other materials, and better than most synthetic rubbers in terms of comprehensive performance. The disadvantages are poor resistance to oxygen and ozone, easy to aging and deterioration; poor resistance to oil and solvents, low corrosion resistance to acids and alkalis, and low heat resistance. Operating temperature range: about -60℃~+80℃.
Making tires, rubber shoes, hoses, tapes, insulating layers and sheaths of wires and cables, and other general products. It is especially suitable for the manufacture of torsional vibration eliminators, engine shock absorbers, machine supports, rubber-metal suspension components, diaphragms, and molded products.
