Good Compatibility Of Plasticizer

Plasticizer refers to the addition of plastic agents to improve the fluidity of resins during the molding process, and to make the products flexible organic substances. It is usually a high boiling, volatile viscous liquid or low melting point of solid, generally not with plastic chemical reaction.

Plasticizer must first and resin have good compatibility, the better the compatibility, the better the effect. Add plasticizer to reduce the glass conversion temperature of plastics, Plasticizer make hard and rigid plastics soft and pliable. Generally also requires plasticizers colorless, non-toxic, odorless, light, heat, cold, volatile and migration of small, non-flammable and chemical stability is good, cheap and easy to get. In fact, a plasticizer cannot meet all of the above requirements.

Plasticizer according to its role of the main plasticizers, that is, solvent-type plasticizers, auxiliary plasticizers, that is, non-solvent-based plasticizer; Plasticizer According to its chemical structure, it is classified as phthalic acid ester, fatty acid ester, phosphate ester, polyester, epoxy ester, chlorine-containing compounds and so on. Commonly used plasticizers have dibutyl phthalate (DBP), phthalic acid dioctyl ester (DOP), Plasticizer epoxidized soybean oil, phosphoric acid tri-toluene ester, diphenyl phosphate, dioctyl succinate, chlorinated paraffin, etc. PVC is the main end user of these plasticizers. The main application fields of Plasticizer PVC are wire, cable, flooring and wall veneer, building materials, automobiles and packaging materials.

Plasticizer is the largest in all plastic auxiliaries. China's total capacity of about 1 million tons, plasticizer to comprehensive performance, price excellent phthalate esters, the world's four major production and consumption countries and regions-the United States, Western Europe, Japan, Plasticizer China's consumption accounted for $number.
