Fillers / Extenders

Fillers and extenders are added to adhesive formulations in order to reduce cost, improve processing and performance properties. The use of fillers and extenders can also impair certain properties, hence the formulator must balance the expected improvements against possible property decline. Fillers and extenders generally have different functions which may overlap and then they can be thought of as serving the same purpose depending on the application. Make your selection process easy by getting in-depth knowledge about fillers and extenders, their effects, applications and formulation examples.

Pressure sensitive adhesives, when in the dry state, are aggressively tacky at room temperature and possess a high degree of "quick stick" or initial grab. They can adhere to a variety of dissimilar materials without the need for much more than slight pressure. Often the pressure is applied by hand, but rollers, presses, and other mechanical devices can also be used. There’s always a scope for tailored performance for a particular high-end application. But, how to select the right additive for your requirement? Learn here, the additives and polymers that are used in pressure sensitive adhesives and how overall performance properties...
