High-Purity Dioctyl Terephthalate(DOTP) Plasticizer CAS 6422-86-2
Sinochem is a major Dioctyl Terephthalate supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Dioctyl Terephthalate.
DOTP colorless transparent oily liquid, it can be used for cable materials and also be used for the production of artificial leather films. In addition, it has excellent compatibility and can also be used as a plasticizer for polyvinyl butyral, nitrile rubber etc.
- Eco-Friendly & Phthalate-Free Safety: Formulated with zero regulated phthalate esters, DOTP fully complies with strict international regulations (such as REACH and RoHS).
- Superior Electrical Insulation: Due to its excellent volume resistivity and minimal volatile mass loss under continuous thermal stress, DOTP significantly upgrades the compounding performance of 70°C and 105°C premium wire and cable insulation compounds.
- Outstanding Migration & Extraction Resistance: Compared to traditional ortho-phthalate plasticizers like DOP, the linear/para-structure of DEHT enhances its cross-linked physical interlocking within the PVC matrix, drastically reducing oil/water extraction and premature embrittlement.

Package: 25L/200L/1000L
Storage: Sealed packaging, placed in a cool and ventilated place, away from heat, sunlight and moisture, stored and transported in accordance with general chemical regulations.
Safety Protection: It may be irritating to the skin and eyes. When using, be careful to avoid contact with the skin and eyes, and take appropriate protective measures, such as wearing gloves and goggles. Make sure to operate in a well-ventilated area and avoid inhaling its vapor. In case of accidental contact or inhalation, move to a ventilated area immediately, rinse the affected area with clean water, and seek medical attention immediately.
Our premium grade DOTP is engineered to meet and match the technical benchmarks and performance standards of major global commercial equivalents. It can be directly utilized as a drop-in replacement or formulation match for mainstream market alternatives such as Eastman 168 Plasticizer, Palatinol DOTP, LGflex GL300, and UPC Group UN488. This ensures seamless manufacturing transitions, eliminating the need for complex recalibrations of your existing polymer processing lines.
