Bis(2-ethylhexyl) terephthalate
It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is referred to as octyl. This colorless viscous liquid is used for softening PVC plastics and is known for chemical similarity to general purpose phthalates such as DEHP and DINP, but without any negative regulatory pressure.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Terephthalate Plasticizers Terephthalate esters, particularly di-2-ethylhexyl terephthalate, are the most popular replacements for DEHP. Their low cost and long history as commercial plasticizers are their most attractive features. Dialkyl terephthalates with sidechains containing more than 8 carbon atoms have limited compatibility with PVC.

PEP Report 62B reviews the technology for producing alternative plasticizers. Dioctyl terephthalate (DOTP) from terephthalic acid and 2-ethylhexanol[1] Dioctyl adipate (DOA) from 2-ethylhexanol and adipic acid Diisononyl phthalate (DINP) from esterification of phthalic anhydride with isononyl alcohol[2]
Dioctyl Adipate - Silver Fern Chemical Inc.
Dioctyl Adipate CAS: 103-23-1. Dioctyl adipate, or DOA, is an oily liquid that is most frequently used as a plasticizer for PVC. It’s light in color and may be used in combination with other plasticizers or by itself. DOA is soluble in oil but not water. Because of its low cost, suitable properties and manufacturing by many companies, DOA
Evaluation performance of multiple plasticizer
In this study, several types of plasticizers, namely dioctyl adipate (DOA), diisononyl phthalate (DINP), dioctyl terephthalate (DOTP) and epoxidized soybean oil (ESO) were added into the PVC matrix to enhance the flexibility of PVC compounds.
- What is Dioctyl adipate?
- DOA, dioctyl adipate is a primary plasticizer. It is the most important in the adipate group, it offers a high efficiency, better flexibility properties at low temperatures and resistance to the loss of color by exposure to heat and ultraviolet light.
- 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 plasthall DOA?
- Plasthall DOA is chemically the same as MONOPLEX® DOA but with looser specifications on color and acid value. In plastisols, Plasthall DOA offers low initial viscosity and excellent viscosity stability Plasthall DOA is often used to improve the viscosity and viscosity-stability characteristics of phthalate based plastisols.
- What is dioctyl ester (DOP) & chlorinated paraffin wax?
- DOP, dioctyl ester is a primary plasticizer widely used in the PVC industry specially in flexible applications like; cable, footwear, hoses, profiling, extrusion, laminates and film. Chlorinated Paraffin Wax formulations are used in a wide range of industrial applications including flame retardants, paints and coatings.

- What is adipate used for?
- It is the most important in the adipate group, it offers a high efficiency, better flexibility properties at low temperatures and resistance to the loss of color by exposure to heat and ultraviolet light. It is used in PVC applications offering better properties at low temperatures compared to phthalates.
