Varieties of plasticizers
There are many plasticizers, and all kinds of plasticizers can be divided into two types: Main plasticizer and auxiliary plasticizer.
The main plasticizer with two formic acid ester and phosphoric acid esters, auxiliary plasticizer with aliphatic dicarboxylic acid ester epoxy etc.. According to the structure classification of plasticizer, plasticizer varieties can be divided into: two formic acid esters, aliphatic dicarboxylic acid esters, epoxide, polyester etc..
O-phenyl two carboxylic acid two (2- ethyl hexyl) ester (DOP) has high plasticizing efficiency, good volatility, migration resistance, water resistance, weather resistance and other comprehensive properties. The production of soft PVC calendered films, mainly plasticizer in DOP and adipic acid two (2- ethylhexyl) ester (DOA) for cold resistant plasticizer.
The epoxy fatty acid ester plasticizer has good thermal stability and cold resistance. The commonly used varieties are epoxy stearic acid 2- ethyl hexyl ester, epoxy soybean oleic acid 2- ethyl hexyl ester and so on.
The high barrier polyvinylidene chloroethylene (PVDC) film for food packaging should be added with a proper amount of 8~10phr nontoxic plasticizer. The main products are acetyl tributyl citrate and acetyl citric acid three (2- ethylhexyl) ester, decanedioic acid two (2- ethylhexyl) ester (DOS) etc.. These plasticizers are also nontoxic plasticizers commonly used in PVC.
The main properties of several plasticizers:
Plasticizers are substances that are added to polymer polymerization systems to increase their plasticity, flexibility, or expansibility. Since 1868 hieatt cloth made of camphor as cellulose nitrate plasticizer has been increasing very fast development of plasticizer, it in all the plastic processing additives in the production and consumption of the largest, most varieties. According to chemical structure, plasticizer varieties can be divided into two kinds: ortho benzoic acid esters, aliphatic two component esters, phosphate esters, epoxide, terephthalate esters, polybenzoic esters, petroleum esters, chlorinated paraffins and polyester plasticizers.
Increase mechanism of plasticizer plasticizer is inserted between the molecular chains of polymer, weaken the stress of polymer chains, the increase of polymer chain mobility, reduces the crystallinity of polymer chains, so that the plastic polymer increases, the main factors that is against the plasticizing effect of polymer molecules the molecular chain chain and polymer crystallinity, and they depend on the polymer chemical and physical structure.
When plasticizers are added to the polymer, the interaction between plasticizer molecules, plasticizers and polymer molecules is important. Unless all these interactions (plasticizers and plasticizers, plasticizers and polymers, polymers and polymers) are at the same hour, there is no possibility of plasticizing and anti plasticizing.

Shipping port: Shanghai port
Price quotation validity: 15 days
Entry time: 15 days (inspection declaration)
Export authority: the company's right to import and export
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.
A light yellow transparent oily liquid. The molecular weight is 426. Relative density (250 C) 0.911~0.913. The refractive index is 1.449~1.451. Solidification point -400C. The boiling point is 3770C (760mmHg). The ignition point of 257~2630C. Compatible with PVC, cold resistant plasticizer. It has good resistance to cold, heat and light, but is poor in resistance to migration and water resistance. Some countries are allowed to use food packaging materials.
Epoxy soybean oleic acid 2- ethyl hexyl ester, also known as epoxy soybean oleate isooctyl, light yellow oil like liquid. Relative density (250C) 0.92~0.98. The refractive index (250C) 1.4580~1.4585. Flash point (cup method) >2000C. Auxiliary plasticizer and auxiliary heat stabilizer. The cold resistance, resistance to migration and oil resistance are better. Non-toxic。
Epoxy stearic acid 2- ethyl hexyl ester, also known as epoxy stearate octyl or epoxy eighteen isooctyl, light yellow oil like liquid. The molecular weight is 410. Relative density (200C) 0.900~0.910. The refractive index (250C) is 1.4537, and the solidification point is -13.50C. Flash point 2650C. Compatible with PVC. Auxiliary plasticizer and auxiliary heat stabilizer. Heat resistance, cold resistance, weatherability, volatile and extractable resistance. Some countries are allowed to use food packaging materials.
Acetyl tributyl citrate, colorless oily liquid. The molecular weight is 402. Relative density (250C) 1.046. The refractive index (25.50C) 1.4408. Solidification point -800C. Flash point (cup method) 2040C. The citrate plasticizer is widely used as a plasticizer, which is compatible with PVC, PVDC and so on. It can be used as a PVDC plasticizer. The heat resistance, cold resistance and water resistance are good. Nontoxic and odorless. Some countries have been allowed to use food packaging materials.
Acetyl citric acid three (2- ethyl hexyl) ester, colorless oil like liquid. The molecular weight is 571. Relative density (250C) 0.983. Flow point -19.40C. Flash point (cup method) 2240C. PVC, PVDC plasticizer. Cold resistance, good volatility. Nontoxic, some countries allow for the use of food packaging materials.
In order to overcome the shortcomings of the surface migration of PVC products and the precipitation on the surface of products, polymer plasticizer has been developed at home and abroad. For example, the PVC/TPU elastomer obtained by thermoplastic polyurethane (TPU) instead of DOP (TPU is 50%), the tensile strength is 23Mpa, and the elongation at break is 450%.
In addition, a soft PVC product with tensile strength of 17Mpa and a breaking elongation of 350% can be obtained by mixing 41% EVA - CO three - copolymer in PVC. The results show that the plasticizing efficiency of the polymer plasticizer is not as good as the low molecular plasticizer, and it is better to use both of the plasticizers and the plasticizer. In recent years, European and American countries have produced a variety of soft PVC products with polymer plasticizer, especially Elvaloy 742.
