      Butyl rubber due to equate long molecular chain structure characteristics cycle, and low temperature, it is not easy to crystallization has good cold resistance. The rubber glass transition temperature higher than the natural rubber, only isoprene rubber, butadiene rubber and ethylene-propylene rubber in**0 ℃, low temperatures still have softness. In their molecules within the chain has the big resistance, so in alternating stress amplitude attenuation, faster, absorb shock and vibration performance is good, in**0 ~ **0 ℃ scope all can keep a good vibration damping sex. Because of butyl rubber in the state has, so the crystalline rubber have higher tensile strength and elongation at break. This means that the rubber don't match carbon black people for strong has good intensity, it can be used to manufacture of light color products.
       Butyl rubber has excellent air tightness, for all its air-tightness of rubber. In normal temperature, butyl rubber air coefficient for 1/*0 of the natural rubber, butadiene rubber of 1/*5, 1/8 of the styrenebutadiene rubber, 1/*3 of the ethylene-propylene rubber, 1/2 of acrylonitrile-butadiene rubber. In addition, the rubber also has excellent heat resistant, weather resistance, resistance to ozone aging and corrosion resistance to chemicals such as candle performance. After special formula design, butyl rubber can be in **0 ~ **0 ℃ conditions used for long, heat-resistant limit of **0 ℃; The rubber products in long-term bare light and air, its performance changed little, especially the ozone resistance aging performance is better than the natural rubber *0 to *0 times; Butyl rubber to except strong oxidizing strong acid outside of the acid, alkali and oxidation reduction-all have excellent resistance to solution patience, in alcohol, ketone and ester polar solvents etc, the swelling sex is very small.
