Product Description

Low molecular weight polyisobutylene (MW ~1,350) is a viscous, tacky polymer with superior barrier properties and chemical inertness. It is widely used as a plasticizer, thickener, and adhesion promoter in industrial formulations.

Applications:

Adhesives & Tackifiers: Enhances cohesion and tack in pressure-sensitive adhesives.
Viscosity Modifier: Functions as a rheology modifier in lubricants and sealants.
Coatings & Protective Films: Improves moisture resistance in specialty coatings.
