Polyisobutylene (PIB), a versatile chemical raw material, plays an indispensable yet often unnoticed role in people’s daily lives. Though rarely mentioned in public discussions, its unique properties make it a key component in numerous common products.
In automotive maintenance, PIB is widely used as an additive in lubricants. Its excellent viscosity stability and resistance to high temperatures help reduce wear between engine parts, ensuring smoother operation and extending the service life of vehicles. Beyond automobiles, PIB serves as a critical ingredient in adhesives and sealants. Its strong bonding capability and resistance to water and chemicals make it ideal for household adhesives, ensuring long-lasting adhesion for items like furniture and decorative materials.
Additionally, PIB finds application in food packaging. When used as a coating material, it enhances the barrier performance of packaging films, preventing moisture and oxygen from entering, thus helping preserve the freshness of food products. Its non-toxic and stable characteristics also meet strict safety standards for food-related materials.
While consumers may not recognize its name, polyisobutylene quietly supports the functionality and reliability of many everyday products.
