Polyisobutylene 950 (PIB 950)

Description

Polyisobutylene 950 (PIB 950) is a high molecular weight polymer derived from isobutylene monomers. It is a water-white, transparent, and viscous liquid known for its excellent stability, low volatility, superior dielectric properties, and strong film-forming ability. Commonly referred to as butyl rubber, PIB 950 is one of the most widely used synthetic elastomers in multiple industries.

This grade of Polyisobutylene is colorless, resistant to acids, non-drying, and completely insoluble in water. It demonstrates thermal stability, oxidation resistance, and strong compatibility with paraffin wax and polyethylene (PE), making it highly versatile. Additionally, PIB 950 provides tackiness in formulations, which is valuable in adhesives and sealants.

Chemex Chemicals is a leading importer and supplier of Polyisobutylene 950 (PIB 950) in India, committed to delivering the best quality grades to both domestic and international customers, along with unmatched technical and after-sales support. PIB 950 is available in different molecular weights, with prices varying by grade. Generally, HR grades are priced higher, and importing in ISO tanks proves more economical compared to smaller packaging sizes.
