Polyisobutylene CAS 9003-27-4

 
Properties:
Polyisobutylene is composed of long-chain hydrocarbon formed by polymerization of isobutene, and is extremely stable under normal conditions. It is transparent non-noxious high-consistency semi-solid polymer free of impurities.


This product is the non-volatile liquid with the stable chemical performances.
There are no residues after the high- temperature volatilizing and thermal
decomposition.The series of this product has the excellent thermal oxidation 
performance. It is impermeable to vapor and other gases.It has hydrophobicity
performance and the good shear performance.


Usage:


polyisobutene (hydrogenated) is an emollient.
Polyisobutylene, sometimes called butyl rubber, and other times PIB, is a vinyl polymer. It's very similar to polyethylene and polypropylene in structure, except that every other carbon is substituted with two methyl groups. It is made from the monomer isobutylene, by cationic vinyl polymerization.
Polyisobutylene is a synthetic rubber, or elastomer. It's special because it's the only rubber that's gas impermeable. That is, it's the only rubber that can hold air for long periods of time. You may have noticed that balloons will go flat after a few days. This is because they are made of polyisoprene, which is not gas impermeable. Because polyisobutylene will hold air, it is used to make things like the inner tubes, liner layers of tires, and the inner liners of basketballs.
