Plasticizer is a processing aid that can improve the processing properties, flexibility and tensile properties of polymer.According to its mechanism of action can be divided into physical plasticizer and chemical plasticizer two categories.Traditionally, physical plasticizers are called softeners, and chemical plasticizers are called plasticizers.Synthetic rubber mainly USES physical plasticizers.After the mass production of radial tire, plasticizer A is widely used in China.It can be uniformly dissolved in rubber, so that the filler quickly mixed, shortening mixing time, plasticizing effect is obvious.

Petroleum operating oil is another physical plasticizer commonly used in rubber processing.High aromatic oils are banned in the European Union because of their carcinogenic risk.
