Name: INEOS PIB Polyisobutylene
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of INEOS PIB Polyisobutylene

Exceptional low-temperature flexibility and elasticity across a wide service temperature range.
Outstanding resistance to water, acids, bases, and polar solvents due to saturated hydrocarbon backbone.
Low gas and moisture permeability, making it ideal for high-integrity barrier applications.
Excellent electrical insulation properties with high dielectric strength and volume resistivity.
Good compatibility with elastomers, tackifiers, and plasticizers for tailored compound formulations.

Typical Applications Of INEOS PIB Polyisobutylene

Butyl rubber modification and halobutyl innerliner compounds for high-performance tires.
Sealants and adhesives requiring long-term weather resistance and low creep.
Protective coatings and linings for chemical storage tanks and piping systems.
Pharmaceutical stoppers and medical device components requiring biocompatibility and extractables control.
Electrical cable jacketing and encapsulation materials for underground and submarine applications.
