Polyisobutylene is a high-molecular-weight synthetic hydrocarbon polymer with outstanding film strength, low volatility, and excellent thermal and oxidative stability. Grades 950, 1300, and 2400 differ mainly in kinematic viscosity, allowing precise formulation of lubricants, greases, adhesives, and fuel additives.

Supplied in 200 kg steel drums or 20 kg pails. Store in a cool, dry, and well-ventilated area away from direct sunlight and oxidizing agents. Shelf life: 12 months.
Q1: Which grade is best for grease formulations?
A1: PIB 950 balances low-temperature fluidity with high film strength.
Q2: Can it improve engine oil performance?
A2: Yes, it enhances viscosity index and shear stability.
Q3: Are samples available?
A3: Small sample pails can be arranged upon request.
