What is the best alternative to DEHP for medical-grade
In addition, TOTM is a much less efficient plasticizer than DOTP, meaning you have to use more TOTM to achieve the same durometer—and plasticizer today is more expensive than PVC resin. Purity. If processed in truly dedicated equipment, DOTP can be produced nearly free of DEHP contamination.
A Comparison of Plasticizers for Use in Flexible Vinyl Medical Product
The plasticizers from Study 3 results included DOP, TOTM, and two polymeric adipate-type plasticizers (BP Amoco Chemicals; Naperville, IL) with molecular weights of 3300 and 1800. When comparing Studies 1 and 2, the relative extractabilities of the common plasticizers DOP and DOA were used, whereas when comparing those two studies with Study 3, only the relative extractability of DOP was used.

Bis(2-ethylhexyl) terephthalate
Bis (2-ethylhexyl) terephthalate. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 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

DOTP is a terephthalate plasticizer & volume taking over the share of DOP & DINP. Di-Octyl Terephthalate, DOTP, extensively used in applications like extrusion, calendaring, injection...
- What is DOTP plasticizer?
- DOTP is a primary non-phthalic plasticizer resulting from the esterification of 2 Ethyl Hexanol with Terephthalic Acid. It offers good mechanical properties and permanence. It provides excellent flexibility, good dielectric properties and similar volatility to DOP. It is suitable for cable cover, vinyl floors and other flexible applications.
- What is DOTP used for?
- DOTP has good electrical and thermal properties. It can replace DOP in PVC plastic electrical wire sheath, and can also be used in the production of artificial leather film. In addition, it has excellent compatibility and can also be used for plasticizing acrylonitrile derivatives, polyvinyl butyral, rubber, nitrocellulose, etc.
- What is the temperature difference between DOTP and DOP phthalate?
- Freezing point is (-)48℃. Boiling point is 383℃ and the ignition point is 399℃. Compared with the commonly used dioctyl phthalate (DOP), DOTP has the advantages of heat resistance, cold resistance, low volatility, resistance to extraction, flexibility, electrical insulation properties, and shows excellent durability in products.
- Is DOTP better than DINP?
- Thus, DOTP appears to be better than DINP in terms of replacing DOPin PVC products, from safety point of view. DOTP plasticizer is almost colourless low viscosity liquid. The viscosity is 410 MPa.s (at 0°C), 63MPa.s (at 25°C), and 5 MPa.s (at 100°C). Freezing point is (-)48℃. Boiling point is 383℃ and the ignition point is 399℃.
- Is Dopin PVC better than DOTP?
- The molecular structures of DOTP and DINP occupy more space spatially. This prevents the migration of both molecules from the material and they are not enriched in the environment. Therefore, they are safe for humans. Thus, DOTP appears to be better than DINP in terms of replacing DOPin PVC products, from safety point of view.
- What is the difference between DOP and DOTP?
- In DOTP, in contrast to DOP, the ester radicals are not only branched but are additionally arranged on opposite sides, in the para position, of the benzene ring. The molecular structures of DOTP and DINP occupy more space spatially. This prevents the migration of both molecules from the material and they are not enriched in the environment.
