Bis(2-ethylhexyl) terephthalate
Bis (2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is referred to as octyl.

The advantages and disadvantages of plasticizers - ZhangJia
The advantages and disadvantages of two DOP plasticizers. The advantages are excellent comprehensive properties, good mixing performance, high plasticizing efficiency, good heat resistance and weather resistance, low volatility and good electrical insulation performance. Shortcomings: 1. is not environmentally friendly; 2. is a high price.
Synthesis and application of high-stability bio-based
Taking commercial DOP and DOA as a comparison, we analyzed the mechanical properties, thermal stability, and migration resistance of plasticized PVC films. We expect to use non-toxic and renewable raw materials, create a new potential solution to prepare environmentally friendly plasticizer.
High Stability DOTP Plasticizer Chemical Resistance For High
High Stability DOTP Plasticizer Chemical Resistance For High Insulation Product . Description. DOTP is a substitution of TBC, DOP, DBP, DINP as a eco-friendly plasticizer, with a good physical property and machanical property, electrical and heat resistance, low-temperature volatility, lower glass transition temperature, which endow products with excellent durability, soap water resistance and
- Does DOP plasticizer percentage affect limiting oxygen index and thermal stability?
- The effect of DOP plasticizer percentage on limiting oxygen index and thermal stability of plasticised PVC was investigated in this paper. DOP was added PVC with various quantities (20, 30, and 50) pphr. LOI and thermal stability instruments used for estimating LOI and thermal stability of plasticised PVC as a function to DOP percentage.
- How does DOP affect Loi and thermal stability of plasticised PVC?
- LOI and thermal stability instruments used for estimating LOI and thermal stability of plasticised PVC as a function to DOP percentage. The results showed that the thermal stability of plasticised PVC was improved by increasing DOP percentage, but in the same time has a reverse behavior where the LOI decreases as the DOP percentage increases.
- What is the difference between a plasticizer DOP and a DOTP?
- Compared with the traditional plasticizer DOP, DOTP has less volatility loss and higher stability in long-term use, reducing material aging problems caused by plasticizer migration. High volume resistivity (up to 1×10⁹Ω-m or more), especially suitable for wire and cable insulation materials to ensure electrical safety.
- Which plasticizer is most stable after 10 d?
- After 10 d, the migration trend of all samples had been stabled, it showed that the traditional plasticizer like DOP, DOTP and DOA had basically move out from the PVC matrix in non-polar environment due to their own single structure, while the PVC plasticized with A-ODL showed the best stability in all the environment.
- What is DOTP used for?
- DOTP is the plasticizer of choice for high-temperature resistant cables (e.g., 70°C class cables), and is widely used as a sheathing material for power transmission and communication cables due to its low volatility and high electrical insulation properties.
- Can a-odl-50 be used as a substitute for dop-50?
- In addition, the elongation at break of A-ODL-50 reached to 602.8%, 5.3% higher than DOP-50 (587.5%), which showed that A-ODL could be used as a substitute for DOP, indicating its excellent plasticizing efficiency and mechanical properties.
