The polyester plasticizer
can be used for PVC products, especially as a high-grade PVC products additives, Polyester plasticizer widely used in PVC products, the effect is obvious
。Widely used in oil-resistant cable, gas pipe, waterproof membrane, artificial leather, shoe material, a high-temperature wire coating layer, water tank seal, a variety of equipment (including refrigeration equipment, motor vehicles) gasket, moldings; interior decorations; electrical tape; oil and gasoline-resistant special products.
In contact with food, including packaging film, beverage hose, dairy machinery, and cap gasket.
The role of the Polyester plasticizer
in PVC products：
1, Polyester plasticizer for rubber products, can give the rubber vulcanization heat resistance, oil resistance, anti-swelling and migration resistance, can improve the rubber processing performance. Such as reducing the viscosity of the rubber, to improve the resilience and elongation of vulcanized rubber tensile strength and tear strength decreased less commonly used in styrene-butadiene rubber and nitrile rubber products.
2, in the Eva-VC graft copolymer resin, the Polyester plasticizer can be used as a hard modifier for PVC doors, windows and other profiles in the recipe, plus the amount of 6 to 10 parts of Polyester plasticizer as additives, its products weather resistance, excellent impact resistance；
3, Polyester plasticizer in soft PVC products, plus the amount can reach 20% ~ 70%. With Polyester plasticizer to produce special nitrile rubber powder can be used for PVC, ABS resin, phenolic resin, and other modifiers can increase the toughness of the material and improve the cold impact resistance. Nitrile powder produced by Polyester plasticizer is an ideal raw material for the manufacture of oil-resistant products.
4, the Polyester plasticizer for PVC modifier, the production of PVC modifier for rigid PVC formulations, can improve the brittleness of PVC resin, play an excellent toughening effect. The polyester plasticizer is used in PVC materials, has excellent processing properties and abrasion resistance, especially for oil, water, and various plastic products.
5, polyester plasticizer in PVC use, must make PVC resin and liquid plasticizer (DOP) completely absorbed and then add polymer Polyester plasticizer, the specific method of operation is in the mixing machine PVC completely absorbed when the plasticizer was dry powder, then add a Polyester plasticizer. If the PVC resin, DOP, Polyester plasticizer added at the same time, the Polyester plasticizer before the PVC will first absorb other plasticizer DOP wait, this will lead to incomplete PVC plastication, product processing performance and characteristics of PVC products will be reduced. Because Polyester plasticizer has strong polarity, affinity and other liquid plasticizer characteristics, when Polyester plasticizer to PVC products can play to attract and fix another plasticizer to the surface migration of PVC products, therefore, Polyester plasticizer is considered to be permanent plasticizer, Polyester plasticizer
can be used for various PVC products, especially PVC high-grade products indispensable processing aids.
