Medium Molecular Weight Polyisobutylene

Medium Molecular Weight Polyisobutylene

Medium molecular weight polyisobutylen (PIB) is a synthetic hydrocarbon. It is formed by polymerizastion of isobutene. It is a transparent, semi-solid polymer. Its color can change between colorless and yellowish. Medium molecular weight polyisobutylen products has average molecular weight between 35.000 - 95.000 Mv.
