PIBSI-Polyisobutylene

It is a linear polymer of isobutylene of different molecular weights, and possesses excellent resistance to oxidative and thermal degradation. Polyisobutylene is chemically inert, hydrophobic and impermeable to water vapour or gas. a synthetic liquid polymer, which is a straight chain hydrocarbon structure of Polyisobutylene that is produced in a variety of grades through a rigid low temperature polymerization process. It is derived from raw material consisting of mainly Isobutylene. The compact straight chain structure results in brilliant moisture and barrier properties and is soluble in a wide range of organic solvents.
