Rubber Labels Knowledge

natural rubber (NR) to rubber hydrocarbon (polyisoprene) based, containing a small amount of protein, water, resin acids, sugars and inorganic salts. The utility model has the advantages of large elasticity, high extension strength, high tear resistance and electrical insulation, good abrasion resistance and drought resistance, good processability, easy adhesion to other materials, and superior performance in synthetic rubber in comprehensive performance. The disadvantage is that oxygen and ozone resistance is poor, easy aging, metamorphism, oil and solvent resistance is not good, the first corrosion resistance of acid and base is low, heat resistance is not high. Temperature range: about 60 DEG C ~80. Make tires, rubber shoes, hose, tape, wire and cable insulation and sheath, and other general products. The utility model is especially suitable for making torsional vibration eliminator, engine shock absorber, machine support, rubber metal suspension element, diaphragm and molded product.

Butadiene styrene rubber (SBR), butadiene and styrene copolymer. Performance is close to natural rubber, is the largest yield of general-purpose synthetic rubber, characterized by wear resistance, aging resistance and heat resistance, more than natural rubber, texture is more natural rubber uniform. Disadvantages are: low elasticity, anti bending, anti tear performance is poor; the processing performance is poor, especially the poor, low strength self adhesive rubber. Temperature range: about 50 DEG C ~100. Mainly used instead of natural rubber to make tires, rubber sheets, hose, rubber shoes and other general products.
