Polyisobutylene (PIB)

Polyisobutylene (PIB) is a synthetic rubber-like polymer made from isobutylene molecules. Known for its excellent impermeability, elasticity, and stability, PIB is commonly used in products like inner linings of tires, sealants, adhesives, and lubricants. Its strong resistance to gases and moisture makes it ideal for preventing leaks, while its flexibility contributes to durability. PIB is also valued for its antioxidative properties, helping products last longer without degrading. Overall, PIB is a versatile, high-performance material essential in various industrial applications requiring sealing, cushioning, and barrier properties.
