Selecting Plasticizers for Adhesives and Sealants

Citrate plasticizers are esters of citric acid. They have been used mainly as plasticizers with cellulosics, PVC, polyvinyl acetate, and other polymers used in medical plastics and food contact packaging. Some citrate esters find specialty use in blood bags and food wraps. Citrates are also used in toys produced by the plastisol process.
