Butyl Rubber

Butyl rubber is a synthetic rubber compound or copolymer composed of isobutylene and isoprene. Isobutylene is a chemical compound consisting of methyl and propylene while isoprene, consisting of menthyl and butadiene, makes the rubber unsaturated and able to vulcanize. Today, Butyl rubber is one of the commonly-used synthetic rubber compounds on the market.

Pierce-Roberts Butyl rubber resists abrasion, oxidation, corrosion, and gas permeation, which allows Butyl rubber to prevent the leakage of gas. Additionally, Butyl rubber has a high dielectric strength. Common applications include inner tubes, o-rings, stoppers for medical bottles, and pharmaceutical supplies.
