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.
