2017-12-18 12:10:40
Fatty acid ester plasticizer have good low-temperature performance, but fatty acid ester plasticizers have poor compatibility with polyvinyl chloride, so they can only be used as cold resistant secondary plasticizers and ortho benzene two carboxylates.
The most commonly used varieties of fatty acid ester plasticizers are two octyl adipate and two octyl sebacic acid.
(1) two octyl adipate (DOA). Colorless and odorless liquid, nontoxic, soluble in most organic solvents, slightly soluble in ethylene glycol, insoluble in water, and the critical plasticizing temperature of DOA to PVC is 12L 125 C.
(2) two isodecyl diacid (DIDA). An oily liquid that is clear and easy to flow.
(3) NONYLIC acid two octyl (D0Z). It's almost a colorless transparent liquid.
(4) two butyric acid (DBS) of sebacic acid. It's almost colorless liquid.
(5) sebacic acid two octyl (DOS). It is almost colorless oil - like liquid, insoluble in water and dissolved in organic solvents such as alcohol, benzene and ether.
(6) sebacic acid two isooctyl (DIOS). The colorless clear liquid, soluble in most organic solvents such as ketones, alcohols, esters, aromatic hydrocarbons and fatty hydrocarbons, is slightly soluble in amines and polyols.
(7) two (2 - ethyl butyric acid) three ethylene glycol (3GH). It is a safety glass for PVB film most widely used plasticizer, while its plastic, plastic and acrylic fiber cable PVC is a good plasticizer.
Adipate two octyl or adipic acid two (2- ethyl hexyl) ester, English Name: Dioctyl adipate or Di (2-ethylhexyl) adipate, abbreviation DOA or DEHA. Light yellow to colorless clear clear liquid. Little smell. Insoluble in water, soluble in methanol, ethanol, ether, acetone, acetic acid, chloroform, ethyl acetate, gasoline, toluene, mineral oil, vegetable oil and other organic solvents. It is slightly soluble in ethylene glycol. The substance is harmful to the environment and should pay special attention to the pollution of the water body. Store in a cool, ventilated storeroom. Stay away from fire and heat. Prevent direct sunlight. Keep the container seal. It should be kept separately from the oxidizing agent and avoid the mixture. Equipped with the corresponding variety and quantity of fire equipment. The storage area should be equipped with leakage emergency treatment equipment and suitable collection materials.

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.
Two octyl adipate is a light yellow colorless clear transparent liquid. Little smell. Relative density (d25/4): 0.922. The melting point -67.8 degree C, boiling point 214 degree C (0.67KPa), flash point (cup) 196 degree C, refractive index (n20D) 1.4474, viscosity (20 degree C) 13.7mPa.S. Insoluble in water, soluble in methanol, ethanol, ether, acetone, acetic acid, chloroform, ethyl acetate, gasoline, toluene, mineral oil, vegetable oil and other organic solvents. It is slightly soluble in ethylene glycol.
Two octyl adipate is an excellent cold resistant plasticizer for PVC. It gives excellent low softness and good light, heat stability and water resistance. Adipic acid two octyl is nontoxic and can be used in food packaging materials. The compacting and calendering products of hexadienyl diacid two octyl show excellent lubrication performance and good handle. In the plastic sol, the viscosity of the initial viscosity is low and the viscosity stability is good. DOA is usually used with DOP and other plasticizers and is used for cold resistant agricultural film, wire, board, artificial leather, outdoor water pipe and packaged film of frozen food. DOA can also be used as a plasticizer for many low temperature plasticizers containing rubber and resins such as nitrocellulose and ethyl cellulose.
Adipic acid, isodecyl ester two, density: (20 C):0 966g/cm3: 50'C; freezing point; boiling point: 250 DEG -267 DEG: flash point: 219 degrees: 271 DEG C; ignition point; viscosity: 120 C) 128mPa.s; refractive index: n; 1.4846; expansion coefficient: 0.00074/ (10 DEG -4O DEG C); acid number: 005mg/KOH/g. Water content: less than 0.05%: purity: >99.7%, water solubility (25 degrees C), soluble in most organic solvents and hydrocarbons, insoluble or slightly soluble in glycerol.
Adipic acid two isodecyl ester is an excellent cold resistant plasticizer. Its performance is similar to two octyl adipate (DOA), but its volatility is similar to that of two octyl ester of o-phenyl two formate (DOP), 1/3 of two octyl adipate, and the viscosity of hexadionate two isodecyl ester is good in plasticsol. It has good water resistance.
Adipic acid, two isodecyl ester and polyvinyl chloride, have poor compatibility. They are often used as main plasticizers of o-phenyl two carboxylates and used for products that require cold resistance and durability, such as outdoor water pipes, synthetic leather, general purpose films and sheets, wires, cable sheaths, etc. Two isodecyl adipate can also be used as a plasticizer for most of the synthetic rubber.
Azelaic acid two octyl ester is a good cold resistant plasticizer. Its viscosity is low, boiling point is high, plasticizing efficiency is high, water extraction is small, volatile and migration is small, and has excellent heat resistance, light resistance, electrical insulation and viscosity stability to plasticizer, and cold resistance is better than adipic acid two octyl ester (DOA). It has good compatibility with polyvinyl chloride, vinyl chloride, vinyl acetate copolymer, polystyrene, polyvinyl acetate, cellulose acetate butyrate, nitrocellulose, ethyl cellulose and so on. It is suitable for artificial leather, thin film, thin plate, wire and cable sheath, plasticizer and so on, which can give products good low temperature performance. It can also be used as a plasticizer for synthetic rubber such as NBR, butadiene rubber, chloroprene rubber and other plasticizers.
