CAS: 6422-86-2
Dioctyl terephthalate (CAS:6422-86-2), The IUPAC name of Bis(2-ethylhexyl) terephthalate is bis(2-ethylhexyl) benzene-1,4-dicarboxylate. With the CAS registry number 6422-86-2, it is also named as Terephthalic acid, bis(2-ethylhexyl) ester. The other registry number is 144981-82-8. It is clear colorless liquid which is insoluble in water. It is low toxic and flammable. So the storage environment should be ventilate, low-temperature and dry.
Application industries:
· DOTP has good resistance to electricity and heat, which can replace DOP in PVC plastic electrical wire sheath and can also be used in the production of artificial leather film.In addition, with excellent compatibility, it can also be used 1.in the plasticizing of acrylonitril e derivatives, polyvinyl butadiene, nitrile rubber, cellulose nitrate, etc.And plays the role of improving the hardness and deformation of products, in nitrile rubber, neoprene, epdm products can be used as softener.Especially used in cable material with good plasticizing effect and low volatility, widely used in the requirement of heat resistance, high insulation of all kinds of products, is the production of temperature resistant 70ºC cable material and other requirements of volatile PVC products ideal plasticizer.
· DOTP is used for PVC products in cars, and can solve the problem of fogging of glass Windows.DOTP is also used for high quality lubricants or lubrication additives for paints, coatings and precision instruments for high quality furniture and interior decoration, nitrocel varnish additives, paper softeners, polyester amide bi-directional stretch films, film plastic crafts, plasma storage bags, etc.
· Because the linear molecular structure of DOTP is similar to DOS and DOA, it has good cold resistance.
· The volume resistivity of DOTP is 10-20 times higher than that of DOP, and it has excellent migration resistance.
· Because DOTP does not contain phthalates, it is not within the scope of 16 kinds of phthalate-containing plasticizers restricted in the EU and other countries, so it is an excellent environmental protection plasticizer.
