Description
What is PIB-950
PIB-950 is a grade of polyisobutylene (PIB) — a viscous, synthetic polymer.
“950” refers roughly to its molecular weight/viscosity class. It’s a mid-/moderate weight PIB, not very low, not extremely high.
It’s a non-drying, non-volatile, hydrophobic liquid polymer. Chemically stable, inert to many chemicals, with good resistance to oxidation, UV, aging
