Application of polyester plasticizer in PVC plastic products

polyester plasticizer is a polar high molecular polymer, which has good compatibility with PVC. When added to PVC formula, it can advance the plasticization time of PVC to varying degrees. As a formula raw material and auxiliary agent, it is often combined with DOP and epoxy soybean oil. Because polyester plasticizer has strong polarity, its affinity with DOP in the formula is also related to the characteristics of other liquid plasticizer products, When polyester plasticizer is used in PVC products, it can attract and fix other plasticizers not to migrate to the surface of PVC products. Therefore, polyester plasticizer is known as a permanent plasticizer. Polyester plasticizer can be used in all kinds of PVC products, especially in high-grade PVC products

polyester plasticizer can be used in PVC products, especially as an auxiliary agent for PVC high-grade products. It is widely used in oil resistant cables, gas pipes, waterproof coiled materials, artificial leather, shoe materials, high-temperature wire coating before experiments, water tank sealing strips, gaskets and fillets of various equipment (including refrigeration equipment and motor vehicles); Indoor high-grade decorations; Electrical tape; Special products resistant to oil and gasoline. In terms of food contact, it includes packaging film, beverage hose, dairy machinery, bottle cap gasket, etc

polyester plasticizer used in rubber products can endow rubber with vulcanization heat resistance, oil resistance, swelling resistance and migration resistance, and improve the processing performance of rubber, such as reducing the viscosity of rubber, improving the vulcanization resilience and elongation, and reducing the tensile strength and tear strength of rubber slightly. It is commonly used in styrene butadiene rubber and nitrile rubber products

in EVA VC graft copolymer resin, polyester plasticizer can be used as a hard modifier for PVC door, window and other special-shaped materials. The wood plastic material has the texture of natural wood. After 6~10 parts of polyester plasticizer is used as an auxiliary, the product has excellent weather resistance and impact resistance; The addition of polyester plasticizer in soft PVC products can reach 20%~70%. The special nitrile rubber powder produced by polyester plasticizer can be used as modifier for PVC, ABS resin, phenolic resin, etc., which can increase the toughness of the material and improve the cold shock resistance. The nitrile powder produced by polyester plasticizer is an ideal raw material for manufacturing oil resistant products. Using polyester plasticizer as PVC modifier and PVC modifier as rigid PVC formula can improve the brittleness of PVC resin and play an excellent toughening effect. Polyester plasticizer is used for PVC materials, with excellent processability and scratch resistance, especially for various plastic products resistant to oil and water

during the use of polyester plasticizer in PVC, it is necessary to fully absorb PVC resin and liquid plasticizer (DOP) before adding polymer polyester plasticizer. The specific operation methods are as follows: Jinan new era Gold Testing Instrument Co., Ltd. will tell you how to avoid changing the loading of the experimental machine? When the PVC in the mixer completely absorbs the plasticizer in the form of dry powder, the polyester plasticizer is added. If PVC resin, DOP and polyester plasticizer are added at the same time, the polyester plasticizer will first absorb DOP and other plasticizers before PVC, which will lead to incomplete plasticization of PVC, and the processing performance of products and the characteristics of PVC products will decline. The role of DOP in the formula is that it can still use various adhesives to bond with polyester at high temperature to play a synergistic role in plasticizing and improve the performance of PVC products. Polyester plasticizer can play an irreplaceable role in improving the quality of products. Adding more than 15 parts of polyester plasticizer into the formula can greatly improve the properties of the product
