High polymer has good compatibility with PVC. Adding PVC formula can make PVC plasticizing time advance to different degrees. As a formula material and auxiliary, it is often used in combination with DOP and epoxidized soybean oil. Because polyester plasticizer has stronger polarity, it is related to the compatibility of DOP in the formula and other liquid plasticizer products. When polyester plasticizer can play a role in attracting and fixing other plasticizers not to migrate to the surface of PVC products, polyester plasticizers are known as permanent plasticizers. Polyester plasticizers can be used as an indispensable processing aid in all kinds of PVC products, especially in PVC high-grade products. Polyester plasticizer is polar.

Polyester plasticizers can be used in PVC products, especially as additives for PVC high-grade products. They are widely used in oil resistant cables, gas pipes, waterproofing membranes, artificial leather, shoe materials, high temperature wire coating, sealing strips for water tanks, gaskets and pads for various equipment (including refrigerating equipment, motor vehicles), interior decorations, electrical tape, special products for oil and gas resistant, etc.

In terms of food contact, they include packaging films, beverage hoses, dairy machinery and bottle cap gaskets.

Polyester plasticizers are used in rubber products, which can give rubber the heat resistance, oil resistance, swelling resistance and migration resistance. It can improve the processing performance of the rubber, such as reducing the viscosity of the rubber, increasing the resilience and elongation of vulcanization, and reducing the tensile strength and tear strength of the rubber. It is commonly used in styrene butadiene rubber and nitrile rubber products.

In EVA - VC graft copolymers, polyester plasticizers can be used as hard modifiers for PVC door and window profiles. The addition of 6~10 polyester plasticizers as additives can improve the weatherability and impact resistance of the products. Polyester plasticizer can reach 20%~70% in soft PVC products.

Special acrylonitrile butadiene rubber powder is produced by polyester plasticizer. It can be used as modifier for PVC, ABS resin and phenolic resin. It can increase toughness and improve cold impact.

The nitrile powder produced by polyester plasticizer is an ideal raw material for making oil resistant products. Polyester plasticizer is used in PVC modifier. The modified PVC modifier is used in the rigid PVC formulation, which can improve the brittleness of PVC resin and play an excellent toughening effect.

Polyester plasticizer is used in PVC materials. It has excellent processability and scratch resistance. It is especially suitable for all kinds of plastic products that are resistant to oil and water.

Polyester plasticizer in the use of PVC, the PVC resin and liquid plasticizer (DOP) must be completely absorbed before adding polymer polyester plasticizer. The specific operation is to add polyester plasticizer when the PVC completely absorbs the plasticizer in the mixer.

If PVC resin, DOP and polyester plasticizer are added at the same time, polyester plasticizer will first absorb DOP before PVC and wait until other plasticizers, which will lead to incomplete plasticization of PVC, and the processing properties of products and the properties of PVC products will drop.

The function of adding DOP in the formula is to play a synergistic role with plasticizer and improve the performance of PVC products. Polyester plasticizer can play an irreplaceable role in improving the quality of products.

Adding more than 15 quantities into the formula, polyester plasticizer can improve the properties of the products.
