The polyester plasticizer is the polar high polymer, has the very good compatibility with PVC, joins in the PVC formula, can cause PVC to plastify the time to have varying degree being ahead of time, takes one formula raw material and the assistant, often with DOP, the epoxy soybean oil duplicate matches and uses, because the polyester plasticizer has the strong polarity, with DOP in formula endophilicity also with other liquid plasticizer product characteristic related, when the polyester plasticizer used in the PVC product being able to play has attracted and fixes other plasticizer not to the PVC product surface migration role, therefore the polyester plasticizer had name of the permanent plasticizer, the polyester plasticizer may use in each kind of PVC product, specially in PVC high-grade product essential one kind of processing assistant.
Second： applicable scope ：
The polyester plasticizer may use in the PVC product specially takes the PVC upscale product assistant, widely applies in the oil resistant electric cable, the gas main, the waterproof volume material, the imitation leather, the shoes material, the thermostable wire rod inhibitor, the water tank packing, each kind of equipment (including refrigeration plant, motor vehicle) filling piece, fillet; Indoor high-quality ornament; Electrical adhesive tape; Oil resistant bears the gasoline the special product and so on. In contact food aspect including packing thin film, drink hose, dairy products machinery and bottle cap filling piece and so on.the polyester plasticizer uses in the rubber products, can entrust with the rubber by the curing thermal stability, the oil resistance, the anti-swelling capacity and bears the migratory nature, can improve the sizing material processing shop characteristics, if reduces the sizing material the viscosity, enhances the curing the rebound elasticity and the elongation ratio, drops to the sizing material longitudinal strength and the peel strength is small, commonly used in styrene - - divinyl rubber and in Ding nitrile rubber products.In EVA-VC stem grafting it gathers in the resin, the polyester plasticizer may take the flinty modifier use, uses in the PVC gate, in the window iso- molding formula, after the increment 6~10 polyester plasticizer take the rib medicinal preparation, its product's weathering resistance, shocking are fine; The polyester plasticizer in the soft PVC product, the increment can achieve 20%~70%, produces the special Ding nitrile rubber powder with the polyester plasticizer, may use in modifier and so on PVC, ABS resin, phenolics, can increase the toughness of material and improve cold shocking. Polyester plasticizer production's Ding Jing the powder is manufacture oil resistant product ideal raw material, uses in the PVC modifier the polyester plasticizer, will produce the PVC modifier uses in the flinty PVC formula, can improve the PVC resin brittleness, has to the limit the good plasticizing effect. The polyester plasticizer uses in the PVC material, has the high quality workability with to bear the abrasion, is suitable specially for oil resistant, the water each kind of plastic products.
The polyester plasticizer in the PVC material use process, after must make the PVC resin and the liquid plasticizer (DOP) absorbs completely, to join the high polymer polyester plasticizer again, the concrete operations method is absorbs completely when mixing roll's PVC the plasticizer assumes does is powdery, again joins the polyester plasticizer. If the PVC resin, DOP, the polyester plasticizer also joins, then polyester plasticizer before PVC will first absorb DOP to wait till other plasticizer, like this will cause PVC to plastify not completely, product workability and the PVC product's characteristic can drop. Joins DOP in the formula the role is plays the plastify with the polyester the synergism, enhances the PVC product the performance, the polyester plasticizer can have a new look to the product quality may not the substitution effect. Joins the quantity in the formula above 15, the polyester plasticizer can enable the product the characteristic to have the big enhancement.
This company produces what the polyester plasticizer uses is US's technology, Japan's formula, improves finely after this factory technology engineer, may substitute the similar imported product. Welcome the general customers to come the rope type test.
