NR1 NR natural rubber elasticity of the elastic modulus of about 3 ~ 6MPa pads customized, extendible to 1000% without breaking. 2 NR crystallized hardness, tensile force under crystallize pads manufacturers, strong self-complementary; high molecular weight pads NR wholesale, mechanical strength. Gums vulcanizates breaking strength of 16.7 ~ 28.4MPa, after the carbon black reinforcement up to 24.5 ~ 34.3MPa. NR repeatedly deformed epigenetic low heat, with good resistance to flex fatigue resistance. Butyl rubber (IIR) ?? rubber and use. Poor adhesion and oil resistance. Heat a large, low room temperature elasticity. Disadvantages: 1, process performance is poor, slow curing, easy to use and other rubber. Poor adhesion and oil resistance. Heat a large, low room temperature elasticity.
