Is butyl rubber oxidized?

However, it is readily attacked by oxidizing chemicals, oils, benzene, and ketones and as a general rule it has also poor chemical resistance to petroleum and its derivatives and many organic chemicals. Moreover, butyl rubbers are sensitive to UV-irradiation (e.g., sunlight exposure).

What are the characteristics of butyl rubber?

Butyl rubber has the chemical resistance characteristic of saturated hydrocarbons. Oxidative degradation is slow, and the rubber may be further protected by incorporating antioxidants. Isobutylene is the major component of bulk rubber. It provides good aging resistance and low gas permeability. Isoprene, a minor component, enhances vulcanizability.

What is the difference between isobutylene and butyl rubber?

Isobutylene is the major component of bulk rubber. It provides good aging resistance and low gas permeability. Isoprene, a minor component, enhances vulcanizability. Butyl rubber is formed from the polymerization of isobutene (isobutylene) with small amounts of chloroprene, isoprene, or butadiene and may be halogenated.

What is the difference between PIB and butyl rubber?

Butyl rubber, sometimes just called "butyl", is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as "PIB" or polyisobutene, (C 4 H 8) n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is based.

Who makes butyl rubber?

Today, the majority of the global supply of butyl rubber is produced by two companies, ExxonMobil (one of the descendants of Standard Oil) and Polymer Corporation, a Canadian federal crown corporation established in 1942 to produce artificial rubber to substitute for overseas supply cut off by World War II.
