Plasticizers

What are plasticizers and how do they affect adhesive performance?

Plasticizers are an additive typically used to soften materials. PVC is a common example. If it does not have plasticizers, it may be listed as UPVC (unplasticized). In terms of adhesive performance, plasticizers can permeate the adhesive and weaken the bond between a tape and a substrate.
