Polyester plasticizer is obtained by polycondensation reaction with polymeric acid polymeric alcohol. It has long-carbon chain and strong plasticizing capability, known as permanent plasticizer. It is a processing AIDs that will not occur precipitate migration，good compatibility with PVC, efficient and non-toxic.

Characters & Applications
Polyester plasticizer has a lot of advantages, such as tasteless, non-toxic, insoluble in water and oil resistance, good thermal stability, good electrical insulation, good compatibility, known as permanent plasticizer
This product can be applied to rigid PVC products by extrusion and injection which can promote the plasticizing properties and can provide excellent melt fluidity. PVC rigid products surface is brightness and transparency is good. The vicat temperature of hard products is not affected.
Polyester plasticizer is used as the radial help low temperature resistant plasticizer in PVC half hard and soft products, which can make the liquid plasticizer less precipitate migration, improve weather resistance of the product and improve the low temperature brittleness of PVC products.
