Products Description
Polyisobutylene (PIB CAS:9003-27-4) is a colorless, tasteless, non-toxic, thick or semi-solid substance with excellent performance, including heat resistance, oxidation resistance, ozone resistance, weather resistance, UV resistance, and acid and alkali resistance. It is widely used in the adhesives and sealants industries due to its excellent tackiness, flexibility, and long-term stability.
Classification for Adhesives & Sealants Applications
- Low Molecular Weight PIB (low viscosity PIB)
Used for viscosity adjustment and tack improvement in adhesive systems.
- Medium Molecular Weight PIB
Main grade used in sealants and pressure-sensitive adhesives due to balanced elasticity and adhesion performance.
- High Molecular Weight PIB
Used in high-performance sealing systems requiring strong elasticity and durability.
Applications in Adhesives and Sealants Industry
Polyisobutylene is widely used in:
- Pressure-sensitive adhesives (PSA)
- Hot-melt adhesives
- Construction sealants
- Automotive sealing materials
- Waterproof membrane systems
- Industrial bonding compounds
