Fillers are one of the most important ingredients in an adhesive, sealant or encapsulant. Some materials contain a single filler, while others have multiple fillers. These fillers may account for up to 50 percent of the product’s ingredients.
“Fillers have been needed in adhesives and sealants for as long as they have been made,” says Daniel Pössnicker, head of the systems and engineering business unit at ViscoTec Pumpen-u. Dosiertechnik GmbH. “The need for thermally conductive fillers continues to increase, due mainly to the large growth in e-mobility and smart appliances.”
