Do our DuraLar™ pressure-sensitive adhesive films (PSA) have good insulation properties? Sort of. PSA film is made from polyester film, which has great insulation properties. However, its adhesive coatings are not meant for exposure to elevated or reduced temperatures. Therefore we can not recommend this material for any sort of insulation application.
We can, on a custom basis, make you a PSA film with adhesives that are optimized for exposure to a specific elevated or reduced temperature. Minimums will apply.
