OPPANOL® - more than just polyisobutene

Polyisobutene (PIB) has been a core business of BASF for more than 85 years. As one of the world's leading producers of PIB, we offer the broadest range of polyisobutenes with different molecular weights. With customers located all over the world, our PIB team acts globally by maintaining strong and caring customer contact across all regions. Our new OPPANOL® N, based on an innovative production process, marks the latest addition to our portfolio.


There is a good reason why we at BASF refer to our polyisobutene as 'the global all-arounder': The unique range of properties, combined in a single product, make our OPPANOL® the solution for a diverse spectrum of different applications. Polyisobutene is suited to enhance manufacturing processes and product effectiveness. Depending on the challenge at hand, the OPPANOL® polyisobutene product family can enable formulations that provide a water vapor barrier, electrical insulation, good adhesion, flexibility at low temperatures (cold flow) or no skin irritation. Our customers can meet their specific requirements by combining the various grades of OPPANOL® to enable tailored solutions. Building on BASF's unique strength to be the market's reliable partner for PIB, this makes OPPANOL® the ideal solution for various applications in a wide range of industries, including the automotive, construction, packaging, electronics and food sectors.
