Commonly used plasticizers in China
This paper briefly introduces the commonly used plasticizers in China. The main plasticizers in China are DOP, DBP, DIDP, DINP, TXIB, DOA and so on.
Two (2 ethyl hexyl) ester of phthalic acid, a common plasticizer in China, is called DOP, Di 1 (2 ethyl hexy1) phthalate in English. It is a colorless or yellowish oily transparent liquid obtained by esterification of phthalic anhydride and 2 ethyl hexanol. There is a special odor of two octyl. The molecular weight of 391, acid value (mgKoh / g) = 0.10, ester content 99% ~ 100%, the relative density of 0 980-0.986 (25 C). The viscosity of 80cp (20 C). The refractive index of 1.4830 to 1.4859 (20 C). It is one of the most widely plasticized Jing plastic processing.
With excellent comprehensive performance. High plasticizing efficiency, low volatility. Naiyong. UV resistant draw. Yi transitional small and cold resistance, softness and electrical properties are very good. It is a kind of ideal primary plasticizer, is also the largest amount of plasticizer, in Hong Kong, Taiwan and the foreign advanced area because of the price and output problems and controversy DOP carcinogenic octanol problem. It has been gradually replaced by other plasticizer.
DBP two n-butyl phthalate DBP, English name Di - N - butyl phthalate. It is a colorless oil - like liquid obtained by esterification of phthalic anhydride and n-butanol. It has a slight fragrance. The molecular weight of 278. acid = 0.1mgKOH / g, ester content is 99% ~ 100%, the relative density of 1042 ~ 1049 (25 C), the viscosity of 17 ~ 22cp (20 C). The plasticizer is one of the widely used. It is cheap and easy to get. It has excellent solubility, dispersibility and adhesiveness. This product has good compatibility with pigment. It is used for tinting film plastic products to join with castor oil. The main disadvantage is that the volatility is large, so the durability is poor. It should be paid attention to when using it.
Phthalic acid two formic acid two ISO Decyl DIDP. English name Diisode - CYL phthatate. It is composed of phthalic anhydride and two Isodecanol (the main component was synthesized by two carbonyl methyl octyl alcohol and three methyl heptyl alcohol mixture) viscous oil liquid and esterification. Slight odor. 446. molecular weight acidity (as acetic acid) = >99% 0.O1%. ester content, relative density (25 C from 0.961 to 0.969), the viscosity of 83-125ep (20 C), 271 C.
It can be used as the main plasticizer of PVC. Its volatility is small. It has good resistance to escaping and water extraction. It has excellent electrical insulation and large molecular weight. Its compatibility, plasticizing efficiency and cold resistance are not as good as DOP. This product contains the product soft little change with temperature. The products are widely used for temperature. Such as cables, plastic sheeting, the heat discoloration, with phenolic antioxidants (such as bisphenol A) and can improve the performance of the.

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.
Phthalic acid two formic acid two isoyl ester DINP, English name Dinonylphthalate. It is obtained from phthalic anhydride and two carbonyl synthesis alcohol (mainly 3, 5.5 and 13 methyl alcohol) and esterification of colorless transparent liquid. The molecular weight of 419, acidity (in adjacent benzene two formic acid) <0 025%. ester content of >99, the relative density of 0965 to 0.972 (25 C). The viscosity of 78 ~ 120CP (20 DEG C). 2i9 flash "C. refractive index 1.4812 (25 C).
Phthalate isononylphtalate two formic acid two is mainly used as a general type of vinyl resin plasticizer. Low volatile, Yi move small, can endow the products with good light resistance, heat resistance, aging resistance and electrical insulation, this product is pumped by the water resistance is better than DOP, but the plasticizing efficiency is less than DOP about 10% lower, cold resistance is poor. Products are not suitable for low temperature applications, due to superior price and quality and other reasons DOP. Taiwan and foreign advanced countries and regions to replace DOP as the main plasticizer used.
2, 2, 4, 13 methyl 1, 3 diol two isobutyrate. English 2, 2, 4 Trimethyl 1.3 to pentaned_d dii~butyrato~o this product is liquid, molecular weight 286, color (APHA) <3O. (acidity with ISO butyric acid) = O 05%, >98% ester content, relative density from 0.942 to 0.948 (20 C), flash (open cup) 143 C, the refractive index of 1.43 (25 C), volume resistivity 1.5 x 10 "n? CIT1. compatibility. Can endow the products with good cold and water resistance, this product can be used as PVC and vinyl chloride copolymer plasticizer. The use of this product can improve the filler content. Eastman production in the United States, the name of the product TXIB.
Two octyl hexyl diacid DOA. English name Dioctyladipate. No package transparent oily liquid which is composed of two have been obtained and octanol anhydride esterification. The molecular weight of 371, ester content is more than 99%, acid value is less than 0.2mgKOH / g. relative density of 0.921 to 0927 (25 C). The viscosity of 12 ~ 15ep (25 C). 2 x 1 open volume resistance (3O cm n? C). It is PVC typical cold resistant plasticizer plasticizer, high efficiency, small heat discoloration, with soft and light products. Good show good lubrication in the processing of products, good hand feeling, and I (P.DINP)) as the main plasticizer for cold resistance film. Frozen food packaging film, wire and cable coating etc.. But the volatility of this product is large, water resistance, fugacity, electrical insulation and other aspects are also inadequate, should be paid attention to in use. Similar two octyl sebacate DOS and all aspects of performance are better than DOA.
