The Universal Selection Source: Adhesives Ingredients

Plasticizers for Adhesives and Sealants

This guide endeavors to direct the formulator through the process of selecting a plasticizer for a specific adhesive or sealant formulation and end-use requirement. Read on to explore the various classes of plasticizers, their functioning, applications in the adhesives and sealants and challenges faced by the plasticizer industry.

Plasticizers


Plasticizers are used in all types of adhesive and sealant formulations. They are used primarily to flexibilize the final bond and to provide improved low temperature properties. However, plasticizers can also supply additional benefits that are important to both the formulator and end-user.

Plasticizers

A large number of different resins and, as a result, a large number of plasticizers are used with adhesives and sealants. There are over 38 general chemical families of plasticizers and multiple types within each family. This makes the process of selecting a plasticizer for a specific adhesive or sealant formulation a very difficult task.

Plasticizers must be considered with regard to compatibility with the base polymer in the formulation, the end-properties that the formulator is trying to achieve, and the type of processing that the adhesive will be subject to during compounding and application.
