IIR (Butyl rubber)

IIR has good chemical stability and thermal stability, the most prominent is air tightness and water tightness. Its permeability to air is only 1/7 of NR, 1/5 of SBR, and its permeability to steam is 1/200 of natural rubber and 1/140 of SBR. Therefore, it is mainly used in the manufacture of various rubber products such as inner tubes, steam pipes, water tires, dam bottoms and gaskets. In addition, there are BIIR and CIIR, which compared with IIR, the polarity and adhesion of rubber is improved, the vulcanization speed is accelerated, and the compatibility and adhesion with other rubber is also improved ‌.
