Plasticizer

A plasticizer (UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, or to decrease friction during its handling in manufacture.. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the raw material during fabrication, or to meet the

Plasticizer addition above a plasticization threshold makes the resin softer and more flexible, reduces modulus and tensile strength, and increases elongation. The degree of change in these properties is a function of both plasticizer type and concentration. The response curve as a function of plasticizer concentration can be near linear

The release of drug from PEO matrices was influenced both by the plasticizer type and concentration. A faster release resulted from water-soluble plasticizers, PEG 8000 and triacetin, and with increasing concentration. However, a slower release was observed with an increase in concentration of water-insoluble plasticizers, VES and ATBC.
