In industrial production, additive is the assisting chemical applied to enhance production process, improve product quality and quantity, or to endow product with certain special application. But large dosage of supplementary material which has great impact on product’s form, structure and property does not belong to additive. Additive has wide application range. Usually, it is named after objects, such as polymer additive, water compound, metal surface finishing agent, etc. additive choice depends on some common factors:

① Application, appearance, smell, contaminant property, endurance, electric property, weather resistance, etc. they all directly influence product’s application.
② Additive adaptability to processing conditions.
③ Additive endurance. Additive losses are mainly from volatilization, withdrawal and migration, thus it is a must to choose proper additive according to product’s applicable environment and processing conditions.
④ Compatibility between additive and polymer, including their miscibility and mutual impact on stability, etc.
⑤ Additive toxicity. Sanitation of such high molecular materials as packaging material of food and medicine, drinking water pipeline, medical apparatus, etc. depend on additive being applied.
⑥ Synergy and counter effects between additives. The right additives play mutual synergy effect and reduce total amount.
