Plastic additives according to their specific functions can be divided into seven categories

Categories:
① to improve the processing performance additives such as heat stabilizers, lubricants and

the like.
② improve machining performance additives, such as plasticizers, toughening agents, etc.
③ additives improve the surface properties, such as an antistatic agent, a coupling agent.
④ improve optical performance additives such as coloring agents. ⑤ improve the aging

properties of additives, such as antioxidants, light stabilizers.
⑥ reduce the cost of plastic additive , such as extenders, fillers and the like.
⑦ impart other specific effects of additives such as blowing agents, flame retardants,

fungicides and so on.
Additive is dispersed in the molecular structure of the plastic, the Plastic chemical will not

seriously affect the molecular structure, and can improve the properties or reduce the cost

of chemicals. Additive to be added, can promote improved plastic substrate processing,

physical, chemical and other functions and increasing

Substrate physical and chemical properties.
