Terephthalate plasticizer
Terephthalic acid ester plasticizer with terephthalic acid (two 2- ethyl) hexyl ester (DEHTP) as the representative of its interaction with DEHP for isomers, terephthalic acid ester plasticizer for DOTP linear molecular structure, besides the plasticizing performance is slightly lower than DEHP, the other physical properties are better than DEHP.
Terephthalic acid ester plasticizer DEHTP electrical insulation is better than DEHP, the volume resistivity is ten times DEHP, the thermoelectric properties of stability, low temperature flexibility is good, suitable for PVC cable. In addition, DEHTP also has the advantages of good anti extraction. Due to the toxicity of DEHTP is low, high safety, water resistance oil resistance, drew strong, had been regarded as non-toxic plasticizer, allowed to use in PVC medical products, children's toys. Although the proportion of DEHTP in the plasticizer market is not high, but because of its non-toxic, the market prospects are very good.
DOTP has been detected by "SGS" without phthalate two formate (16P). It is a new type of environment-friendly and new plasticizer that can replace DOP. The physical and mechanical properties of DOTP are better than that of DOP. This product has outstanding electrical resistance, heat resistance, low temperature volatility, low glass transition temperature and low volatility. It is an ideal plasticizer for producing excellent cable material.
Two octyl terephthalate (DOTP) molecular formula: C24H38O4 is a good performance plasticizer for polyvinyl chloride (PVC) plastics. Compared with the commonly used phthalic acid two octyl ester (DOP), it has the advantages of heat resistance, cold resistance, no volatilization, anti extraction, softness and electrical insulation. It shows excellent durability, soap and water resistance and low soft and soft property in the products. Because of its low volatility, the use of DOTP can fully meet the requirements of wire and cable temperature tolerance. It can be widely applied to 70 degree cable material (IEC IEC standard) and other PVC soft products.
In addition to a large amount of plasticizers used in cable materials and PVC, DOTP can also be used in the production of artificial leather membrane. In addition, with excellent compatibility, can also be used for acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, cellulose nitrate and plasticizer. Can also be used for synthetic rubber plasticizer, coating additives, precision instruments, lubricant, lubricant additives, can also be used as paper softener.
DOTP is a new type of environment-friendly plasticizer (through the EU REACH regulation), with its low price and excellent performance, which can be passed through the reach regulation. And gradually become the mainstream plasticizer. < substituted acetyl citric acid three butyl -ATBC, phthalic acid two octyl -DOP, two butyl -DBP>. It can be used instead of DOP and DBP as the main plasticizer, and it is superior to DOP and DBP on several important parameters. It has many advantages, such as high plasticizer, environmental protection, innocuity, long time of thermal stabilization, good solubility with polymer, low volatility, inhibition of exudation, large volume of filling agent and high brightness of products.
The following are the comparison of the synthetic plant esters with the more common plasticizers on the three DOP/DBP/ATBC markets.
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.
Packing method:
200KG/ net galvanized steel drum (a small pallet loaded 16 tons), 1000KG/IB (a small barrel loaded 18 tons or 23 tons of ISOTANK).
DOP is two octyl phthalate - - the most common universal plasticizer in the market now. However, with the restriction of the EU REACH Regulation on phthalate salts, the mainstream plasticizer market will be gradually withdrawn.
DBP is ----DBP very volatile dibutyl phthalate plasticizer, as well as the synthesis of esters and DOP plants, and different oxide index of DBP is very high, is absolutely can not be used in medical.
ATBC is the most common mainstream environment-friendly plasticizer at present, but its prices remain high and can not reduce the cost of production.
Synthetic plant ester is vegetable oil as raw material (edible vegetable oil waste), it is non-toxic, environmental friendly, can meet the requirements of medical level, and it can inhibit oil emission. Its growth rate is higher than that of DOP and DBP, and its thermal stability time is long. The use of DOP/DBP/ATBC (or other higher price plasticizer) can greatly reduce the production cost of products without affecting the performance indicators.
Two formic acid two phthalate (2- ethylhexyl) ester, phthalic acid ester, alias DOP, two DEHP, two octyl phthalate, chemical formula (formula): C24H38O4 is a kind of special odor colorless transparent liquid, the melting point of -55 Deg. C, boiling 386.9 degrees, 25 degrees in the water solubility of <0.01%, 0.2% the solubility of water in the products. It dissolves in most organic solvents and hydrocarbons, and is slightly soluble in glycerol and glycol. It has good compatibility with most industrial resins. It is partially compatible with cellulose acetate and polyvinyl acetate. It can be used as stationary phase of gas chromatography to selectively preserve and separate aromatic compounds, unsaturated compounds and various oxygenated compounds (alcohols, aldehydes, ketones, esters, etc.), solvents and plasticizers.
The two (2- ethylhexyl) phthalate (2- ethyl hexyl) ester is a colorless transparent liquid with a special odor. The melting point of -55 Deg. C, the boiling point of 386.9 DEG C, C 222-230 (0.53kPa), relative density 0.986 (20/4 C), refractive index 1.4852, the flash point of 217 DEG C, the ignition point of 241 DEG C, the viscosity of 81.4mPa? S, vapor pressure (200 DEG C) 176Pa. At 25 C, the solubility of the product in water is <0.01%, and the solubility of water in this product is 0.2%. It dissolves in most organic solvents and hydrocarbons, and is slightly soluble in glycerol and glycol. It has good compatibility with most industrial resins. It is partly compatible with cellulose acetate and polyvinyl acetate.
