Plastic additives and type of Performance

Plastics compounding, a small amount added to the synthetic resins or compounds, in order to improve the molding process or the performance of a given product of a class of chemical substances. Such materials dispersed in a mixture of synthetic resin or with, does not affect the molecular structure of the synthetic resin.
Performance
The main requirements of the plastic additive are:
Efficient: applications in plastics processing and can effectively play its proper function. Selection should be based on the additive mixing with the comprehensive performance requirements.
Compatibility: synthetic resin with better compatibility.
Persistence: in the plastic processing and application process is not volatile, non-bleeding and non-migratory and non-leaching.
Chemical stability: in plastics processing and the application process is not biodegradable, synthetic resins and other components with chemical reactions.
Non-toxic: no toxic effects on the human body.
Low prices.
Type
Plastic additives according to their specific function can be divided into seven categories: ① improve the processing performance additives such as heat stabilizers, lubricants, etc.. ② improve machining performance additives, such as plasticizers, toughening agents, etc. ③ additives improve the surface properties, such as an antistatic agent,

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 additives, such as extenders, fillers and the like. ⑦ pvc additive impart other specific effects, such as

Blowing agents, flame retardants, fungicides and so on.
