Applicable Base Polymer Properties
PIB has long been used as a basic substance in the compounding of pressure-sensitive adhesives (PSAs). Relative to other known elastomers, synthetic polymers based on isobutylene offer a number of advantages.
Owing to their synthetic production, they are free of unwanted ingredients and due to their complete saturation they are highly stable to oxidation. PIBs are not a skin irritant and adhesives used in medicine (e.g., surgical tape adhesive, transdermal systems) are usually based on PIBs.
