Plasticizers – These help to increase the plasticity of the plastics.

eg. Vegetable oil, camphor, esters of stearic, tri-phenyl phosphate, diethyl phthalate, etc

Functions;

These help to reduce the forces of intermolecular attraction & thereby increases tendency of sliding or moving.

Thus the plastics which are plasticized possess high percentage of flexibility.

They are essentially used in thermo softening plastics.
