Butyl Rubber

详细说明


    Butyl Rubber is a synthetic rubber that is derived from the polymerization composed of Isobutylene at 98% and Isoprene at 2%. The first major application was for the manufacturing of tire inner tubes. As of today, this remains the most significant segment of its market.

    Butyl rubber has low gas, steam penetrability, good dielectric properties, it is oxygen and ozone resistant, stable against acid and alkalis attack, has good light resistance, stable against high temperatures, humidity, dryness, against animal and vegetable oils and fats. Butyl rubber is vulcanized with more active accelerators and at elevated temperatures, it is badly combined with other types of high-unsaturated elastomers Butyl rubber.

    The Bromo butyl rubber derived from reacting butyl rubber with bromine in a continuous process. It is similar to chloro butyl rubber, produced by the same halogenation process.

    The Chloro butyl rubber is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for Isobutylene Isoprene Rubber. Poly-isobutylene, also known as "PIB" or poly-isobutene, is the homo-polymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is based.

    Butyl rubber has excellent impermeability and the long poly-isobutylene segments of its polymer chains give it good flex properties.

    Application: The manufacturing of inner tubes, brewing chambers, rubberized fabrics.
