Polyisobutylenes are a vital part of adhesive and sealant formulations.
PIBs are not new. BASF invented the materials and has marketed a range of polyisobutylenes since the late 1930s. Since then, additional molecular weights and performance characteristics have been added to offer new options and new applications to formulators. The current portfolio of PIB products includes low-molecular-weight (trade named Glissopal), medium-molecular-weight (trade named Oppanol B 10 SFN - Oppanol B 15 SFN) and high-molecular-weight grades (trade named Oppanol B 30 SF - Oppanol B 200).
