Processing aids and plasticizers are chemical additives used in compounds to increase the plasticity, fluidity or lubrication of a material. These processing aids are suitable for use in plastics and rubber compounds. Plasticizers soften polymer compounds in order to improve processing, lower compound viscosity and increase the flexibility of polymer compounds.

Because there is a wide range of chemicals used as processing aids and plasticizers, the individual properties of each compounding material can differ greatly. Depending on a customer’s specific compound, process requirements and chemical compatibility, the correct additive must be selected to ensure proper performance.

Plasticizers, process oils, internal lubricants and other chemical additives are used to improve and enhance the compound processing characteristics of rubbers and plastics. Processing aids can act as softeners, extenders, lubricants, stabilizers, and strengtheners, depending on the needs of the manufacturer. They can be found in a number of products including flooring tubing, beverage bottles, building materials, automobile engine hose, and wire and cable jacketing.
