Fillers / Extenders

Conductive fillers are widely used to promote the electrical and thermal conductivity in adhesives and sealants. Selection of the proper filler and its loading level can have a profound effect on conductivity, cost, formulating characteristics, and final mechanical properties. While, for a specific filler there can be several variances, such as size (mean and distribution), aspect ratio, surface area, and surface chemistry, how can you ensure you have the right material for the success of your product. Whether you are creating a new product or optimizing the existing one, learn everything you need to know about conductive fillers here. Electrical Conductivity...

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...

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 filler and extenders, their effects, applications, and formulation examples.
