Plasticizers are used in all types of adhesive and sealant formulations. They are used primarily to 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.A large number of different resins and 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:The compatibility with the base polymer in the formulationThe end-properties that the formulator is trying to achieve, andThe type of processing that the adhesive will be subject to during compounding and application
