Environmental Plasticizer refers to the addition of plastic additives, improve the fluidity of the resin in the molding process, and make the product flexible organic substances. It is usually a high boiling, difficult to evaporate viscous liquid or low melting point of solids, generally do not react with plastic.

The environment-friendly plasticizer must first have the good compatibility with the resin, the compatibility is better, its plasticizing effect is also better. Adding plasticizers can reduce the glass conversion temperature of the plastic, making hard and rigid plastics soft and flexible. Generally also requires environmentally-friendly plasticizer colorless, non-toxic, odorless, light, heat, cold, volatile and migration of small, non flammable and chemical stability, cheap and easy to get. In fact, only environmentally-friendly plasticizers can meet almost all of the above requirements.

Environmental plasticizers classify as main plasticizer, i.e., solvent-based plasticizer, auxiliary plasticizers, i.e., solvent-free plasticizer, Catalyst-type plasticizer according to their function.  According to chemical structure is divided into phthalic acid esters, fatty acids esters, phosphate, polyester, epoxy esters, chlorine compounds and so on. The commonly used plasticizers are dibutyl phthalate (DBP), Dioctyl phthalate (DOP), epoxy soy oil, tri-toluene phosphate, tri-phenyl phosphate, dioctyl phthalate, chlorinated paraffin, etc. PVC is the main end user of these plasticizers. The main areas of application of plasticizer PVC are wire, cable, floor and wall veneer, building materials, automobiles and packaging materials.

Environmental Plasticizer

The controversy over environmental plasticizers is made up of fresh film, in fact, in addition to as fresh film, PVC products in the human medical, life-related areas of application is very wide, it is difficult to replace all other materials, such as latex gloves, plasma bags, part of blood transfusion, infusion, breathing apparatus, children's toys, artificial leather (used as clothing, shoes, handbags , sofa fabric, etc.). At present, the plasticizer used in these products and other additives in foreign countries have strict provisions or corresponding recommendations, and in China, the production of these products used in most of thehttp://www.bsyplasticizer.com/is still DEHA, DOP, DEHP, DINP and other traditional types of plasticizer. Nowadays, many animal experiments at home and abroad show that these plasticizers are harmful to organism, but some experts also point out that many of them are only completed under certain conditions, and the possibility of using traditional plasticizer to produce PVC products under the existing norms is negligible.
