Polyester plasticizer
Due to the small molecular weight plasticizers such as DOP and PVC polymer matrix interaction is small, so in the process of using easy migration and extraction, so in recent years the development of polyester plasticizer in this aspect to improve greatly, because of high molecular weight plasticizer reduces the production of volatile machining process. In the process of the use of force interaction between molecular chain and PVC chain polyester is far greater than that of small molecules with PVC, so the extract and mobility is very low, greatly increasing the durability of the materials.
Polyester plasticizer by condensation of diacids and diols, the end is not terminated. Increase the durability of polyester plasticizer, high temperature resistant performance is better than single plasticizer, its performance depends on the level of molecular weight, molecular chain structure, polyester plasticizer on the extraction quantity of xylene, gasoline and ethanol dissolved in the smallest, in light oil, polyester plasticizer. Is low volatility and low mobility, excellent resistance to extraction.
At present the common polyester plasticizer for adipic acid polyester plasticizer, Wu Zhaohong [4] studied the effect of plasticizer diol durability of polyester, polyester plasticizer effect of molecular weight on durability significantly higher molecular weight, better durability.
Polyester diols on increasing to a certain extent, the durability of plasticizer with 1, 2 propylene glycol good oil resistance; high migration resistance can choose butylene glycol; neopentylene glycol also has the advantages of both but the price is more expensive.
In addition, ANNIKA LINDSTR? M through the branched polyester of plasticizer showed that the higher the degree of branching, polyester plasticizer durability is better, but the high degree of branching will affect the compatibility of polyester and PVC, so the control of branching in some of the polyester plasticizers durability has great to improve.
Using the method of increasing the molecular weight of plasticizer to improve durability, not only can polyester plasticizer be used, but also polymer blending with PVC is also very common, and polymer elastomers play a role as plasticizer.
M.C.Sunny and other studies show that NBR has good compatibility with PVC. As PVC plasticizer, it can increase the durability of materials, and the migration of DEHP is much less than that of DEHP with small molecular plasticizer. Zhang Fushen and Wu Peixi studied the plasticization of PVC by ELVALOY (ethylene vinyl acetate co three copolymer). It was found that the weathering resistance of ELVALOY is much better than that of DOP, and all properties are outstanding.
In the structure, R1, R2 and R3 represent alkyl, Chloroalkyl, aryl.
It is mainly used as a combustible plasticizer. The greater the dosage, the better the combustibility, the less the alkyl composition in the molecule, the better the combustibility.
Two octyl terephthalate (plasticizer DOTP) raw materials are generally synthesized from the process route of terephthalic acid or two methyl terephthalate as raw material.

Use of two octyl terephthalate (plasticizer DOTP)
1.DOTP has good electrical and thermal properties. It can be used to replace DOP in the sheath of PVC plastic wire and can also be used in the production of artificial leather membrane. In addition, with excellent compatibility, terephthalic acid ester is two PVC acrylonitrile derivatives plastic plasticizer, plasticizer, plasticizer, polyvinyl butyral nitrile rubber plasticizer, plasticizer for cellulose nitrate. The improvement of the product and plays the role of hardness and deformation, can be used as softener in NBR, chloroprene rubber, EPDM rubber and other products three. Especially for cable material, it has good plasticizing effect and low volatility. It is widely used in various products that require heat resistance and high insulation. It is an ideal plasticizer for producing 70 PVC cable material and other volatile resistant products.
2.DOTP is used for the PVC products in the car, which can solve the fog problem of the glass window. DOTP is also used for high quality lubricants or lubricant additives furniture and interior decoration paint, and precision instruments, nitro varnish additives, paper softener, biaxially oriented polyester amide membrane film, plastic bags and other crafts, plasma storage.
3. because the linear molecular structure of DOTP is similar to DOS and DOA, its cold resistance is also better.
The volume resistivity of 4.DOTP is 10-20 times higher than that of DOP, and its mobility is excellent.
5., because DOTP does not contain o-phthalate two formate, it is not an environmental friendly plasticizer in the range of 16 16 kinds of plasticizers containing o-phthalic acid in the European Union and other countries.
Commonly used varieties are: trimethylamine phosphate (TCP): good combustible, heat-resistant, oil resistant and electrical insulation, poor cold resistance.
Three octyl phosphate (TOP): good cold resistance, small volatility, but easy to migrate, poor oil resistance.
Polyester molecular weight in 1000~8000, mainly as oil resistant plasticizer, small volatility, small mobility, oil resistance, water resistance, heat resistance. The main varieties are: sebacic acid series, adipic acid series, phthalic acid two formic acid series and so on. The plasticizing effect of the sebacic acid series is good, and the plasticizing effect of the phthalic acid two formic acid series is poor.
These ester synthetic plasticizers have high polarity and are mostly used in polar rubber. With the increase of the dosage, the physical and mechanical properties of the rubber decreased, but the elongation and the resilience of the rubber increased. The use of a straight chain fatty acid ester can improve the cold resistance of the vulcanizate, but it is easy to extract. In NBR, DOP, DBP, TCP and so on are used as cold resistant products, such as DOA, DOZ, DBS and so on. Polyester plasticizer can be used when oil resistance is resistant to oil. CR usually uses 5~10 plasticizers, but when they are cold resistant products, ester plasticizers should be selected and polyester plasticizers can be used as oil resistant products. SBR: when improving the processing performance, use the petroleum system plasticizer; increase the cold resistance, the use of fatty acids and fatty acid esters of two ester plasticizers. IIR: when improving the cold resistance, DOA and DOS plasticizers can be used to improve the oil resistance, and the polyester plasticizer is selected.
Epoxy plasticizers mainly include epoxy oil, epoxidation fatty acid monoester and epoxidation of four hydrogen phthalate ester and so on. Epoxy plasticizers all contain epoxy structures in their molecules, and have good heat-resistant and light resistant properties.
Epoxidized oils, such as epoxidized soybean oil, epoxidized linseed oil, high epoxy value, generally 6% to 7%, its heat resistance, light resistance, oil resistance and volatile performance is good, but cold and plasticizing effect is poor.
The epoxy value of epoxide fatty acid monoester is mostly 3% to 5%, which is generally good cold resistance, and plasticizing effect is better than DOA. It is mostly used in products that need cold resistance and weather resistance. The epoxidized fatty acid ester with epoxy oleic butyl, octyl, four hydrogen furfuryl ester etc.. The epoxy value of epoxidation four hydrogen phthalate two formic ester is low, generally only 3% to 4%, but they have both epoxy structure and o-benzoic acid two ester structure, so the epoxy oil solubility is improved.
