Dioctyl terephthalate DOTP

Product Name:Dioctyl terephthalate DOTP

Molecular Structure:

Molecular Formula: C24H38O4

CAS NO.: 6422-86-2

Molecular Weight: 390.5561

Capability: It is polyvinyl chloride (PVC) plastic with an excellent performance of the main plasticizer.Compared with DOP, it has the advantages of heat resistance, cold resistance, low volatility, resistance to extraction, flexibility and electrical insulation.In the products show excellent durability, resistance to soapy water and low temperature flexibility.Because of its low volatility, the use of DOTP can fully meet the temperature requirements of wire and cable, can be widely used in 70 ℃ cable material (International Electrotechnical Commission IEC standards) and other soft PVC products.


DOTP has high electric and thermal perfromance and it can be used to replace DOP in PVC plastic electric wire sheath as well as the production of artificial leather film.In addition ,DOTP has excellent compatibility and it can be used in plasticizing of acrylonitirile derivatives ,polyvinyl butyral ,acrylonitrile-butadiene rubber and cellulose nitrate .DOTP plays a role in improving products hardness and deformation therefore it can be used as cut-back asphalt in the production of acrylonitrile -butadience rubber ,chloroprene rubber and EPDM .DOTP uesd in the cable material has a good plasticizing effect and low volatility,widely used in the productions which requirement high heat resistant and high insulation .It is the ideal plasticizer of cable materical with 70 degree Celsius temperature resistant and other PVC products with volatile resistance.

DOTP used in PVC products of cars can solve the problem of the glass window fog .DOTP is also used in the paint or coating of advanced furniture and interior decortaion ,high quality lubricant or lubricanting additive of percision instrument ,nitrocellulose varnish ,paper softener ,polyester amide biaxially film ,plastic film crafts and plasma storage bag .

Due to the similar linear molecular structure with DOS and DOA ,DOTP has excellent cold resistance .

The volume resistivity of DOTP is 10-20 times higher than of DOP ,and the migration is excellent .

DOTP does not contain PAEs and it is not in the range of EU and other countries ‘ limitation of 16 kinds of plasticizer which containing phthalic acid .Therefore,DOTP is an excellent environment protection plasticizer.
