KC 950 (PIB) Polyisobutene
Description
PIB950 is a watery white, hydrophobic, non-toxic low molecular weight polyisobutylene. It has a narrow molecular weight distribution, negligible sulfur content, chemically stable, lightfast, and mesothermal oxidation.
Characteristic
Colorless, odorless and non-toxic
Excellent compatibility with most hydrocarbon polymers and organic substances
Excellent oxidation resistance, ultraviolet resistance Superior plasticity, viscosity (especially good self-adhesiveness).
No residue after thermal decomposition
