Polyisobutenes (PIB) are versatile raw materials for hotmelt and solvent borne adhesive and sealant formulations in various industries, including construction, automotive, electronics and packaging. They deliver a unique set of properties, e.g. gas and vapor barrier, flexibility at low temperatures, adhesion on many substrates and self-healing characteristics. In order to address the sustainability needs of our customers, BASF is now offering both low molecular PIB (Glissopal® range) and medium molecular PIB (Oppanol® B range) as ZeroPCF version, i.e. their product carbon footprint has been reduced by 100% through the use of biomass in combination with renewable steam or electricity based on a certified mass balance approach. These new ZeroPCF polyisobutenes will enable customers to develop adhesives & sealant formulations with very low or zero carbon footprint without compromising on performance, as well as reaching their scope 3 emission targets. The presentation will outline the innovative approach BASF has taken to offer such sustainable solutions, and provide examples how these ZeroPCF products could help to offer more sustainable adhesive and sealant formulations.
