New Dibenzoate Plasticizer Blends for PVC Applications

Dibenzoates plasticizers are well-established and are used in PVC applications. Chemically, these plasticizers are non-phthalates and function well as high-solvating. In the past, new benzoates, dibenzoate blends, and grades were developed to keep pace with formulators' needs. More recently, a new generation of dibenzoate triblend platform has been developed to offer formulators an improved high solvator to complement general purpose plasticizer performance. A basic plastisol evaluation protocol was utilized to help determine how to formulate with these new blends. In addition to the basic data that were developed, examples of performance in starting plastisol formulations are shown. (C) 2014 Society of Plastics Engineers
