Butyl rubber IIR is isobutene and a small amount of isoprenes polymerization, with a small amount of unsaturated group for sulfur, because the movement of methyl stereobarrier molecules is less than other polymers, so less gas permeability, resistance to heat, sunlight, ozone, electrical insulation is good; The resistance to polar solvents such as alcohols, ketones, esters, etc., is large, and the general use temperature range is -54~110 ℃.

Advantages: Impermeability to most general gases, good resistance to sunlight and ozone, and exposure to animal or vegetable oils or oxidizable chemicals. Advantages: Impermeability to most general gases, good resistance to sunlight and ozone, and exposure to animal or vegetable oils or oxidizable chemicals.

Disadvantages: It is not recommended to use with petroleum solvents, gum kerosene and aromatic hydrogen.
