Phthalates have been the most commonly employed plasticizers for PVC, but some of these plasticizers demonstrate many toxic effects on the environment and human beings, which consequently limits the use of
The polyester plasticizer is usually prepared by polycondensation of dibasic acid and diol. It is called “permanent plasticizer” because of its large molecular weight, better water resistance, excellent oil and solvent extraction and longer service

Plasticizer migration can impact a products performance. A plasticizer’s main purpose is to increase a product’s flexibility. So when the plasticizers migrate out from that product, flexibility can go with it. This then
2. Polyester Plasticizers. Polyester plasticizers are a type of superior plastics additives, not only as the primary plasticizers but also as specialty additives in various PVC

Plasticizers are chem. compds. used to increase the softness and fluidity of polymer materials. Phthalate compds. constitute the most common class of compds. used as plasticizers. However, phthalate plasticizers, esp.
Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved. In this paper, a variety of copolyesters are designed and synthesized from succinic acid, hexanediol and other four
- What is polyester plasticizer?
- Polyester plasticizer also has the characteristics of low toxicity and safety. It is suitable for application in the fields with high health and safety requirements for plastic products such as beverage hoses, interior decoration, children’s toys, wire and cable.
- Are polyester plasticizers safe?
- Polyester plasticizers have low toxicity and can be used in plastic articles with high safety requirements. The USA’s FDA has approved its use in food contact materials . Polyester plasticizers have better extraction resistance than traditional phthalates and are highly compatible with PVC resins .
- Which plasticizers are environmentally friendly?
- Currently, commercial environmentally friendly plasticizers include aliphatic acid esters, citrates, epoxy, terephthalates, high-carbon phthalate esters, cyclohexane dicarboxylates (or tetrahydrophthalates), polyesters, phenyl polycarboxylates, etc.
- How do plasticisers leave a polymer?
- Plasticisers, when not chemically attached to polymer chains, can in certain conditions leave the polymer through migration, evaporation or extraction by liquids.
- What happens if a plasticizer migrates out of a product?
- A plasticizer’s main purpose is to increase a product’s flexibility. So when the plasticizers migrate out from that product, flexibility can go with it. This then causes embrittlement. In the case of adhesives, this can cause the adhesive to become unfit for use in an application.
- What are the different types of polyester plasticizers?
- Typically, they are prepared via condensation reactions between dicarboxylic acids (or anhydrides) and diols and have average molecular weights of 1000–8000. Based on the diacid monomers, major polyester plasticizers include adipates, azelates, sebacates, glutarates, phthalates, etc.
