Thermal degradation of esters/ethers derived from tartaric
The esters display good thermal stability out to 700 min at 210 °C. This should permit these compounds to function as plasticizers for a variety of polymeric materials, i.e., the loss of these compounds during polymer processing should be minimal. After initial mass loss, the ethers too display good stability.
A targeted review of bio-derived plasticizers with flame
Then there is di(2-ethylhexyl) phthalate (DEHP), a common plasticizer used for PVC found in blood bags and in medical tubing. Reports detailing concerns about phthalate plasticizers exposure are abundant and the concerns around this plasticizer are well known [2,3,4,5]. When plasticizers are incorporated in PVC, rigidity of the latter reduces
Improving Processing of PET, the World’s Most Recycled Plastic
Phthalates are low molecular weight monoesters made from orthophthalic acid. By comparison, PET is a high molecular weight polyester made from terephthalic acid and these forms are chemically very different. Phthalates (i.e. phthalate ester plasticizers) are not used in the manufacture of PET, and PET itself is not a phthalate.

Plasticizers Derived from Biomass Resources: A Short Review
Ester-amide of ricinoleic acid, as shown in Figure 22, is synthesized and used as primary plasticizer to replace phthalate plasticizers in PVC materials [ 105 ]. Tg of PVC materials blended with 40 wt % of ester-amide of ricinoleic acid reaches 13.5 °C. Figure 22. Synthesis of ester-amide of ricinoleic acid.
- What is the use of phthalate esters in polymer formulation?
- Phthalate esters are commonly used as plasticizer in polymer formulation; in particular for poly (vinyl chloride) (PVC) formulation.
- What are the advantages of phthalate plasticizer?
- The currently most used phthalate plasticizers have the following advantages: (1) no chemical reactions with polymer resins at room temperature; (2) ease of melting; (3) good electrical insulation when added to polymers; (4) enabling high flexibility and strength at low temperatures; (5) low volatility in air; (6) low cost.
- Which phthalate plasticizer is best?
- Policies and ethics Phthalate plasticizers, such as dioctyl phthalate (DOP), di (iso-octyl) phthalate (DIOP), di (2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), di (iso-butyl) phthalate (DIBP), and di (iso-nonyl) phthalate (DINP), have the earliest use, the best performance, the...
- What are the plasticizers used in PVC processing?
- There are many plasticizers used in PVC processing, one of those plasticizers is phthalate esters. Phthalate esters are petroleum-based products which are the most commonly used plasticizers in PVC processing.
- Can aliphatic acid esters be used as secondary plasticizers?
- Aliphatic acid esters, such as dialkyl adipates, dialkyl azelates, dialkyl sebacates, and triglycerides, can only be used as secondary plasticizers because of their low molecular weights, inferior PVC compatibility, and risk of leaching (typically in small amounts as cold-tolerant plasticizers).
- Can Epoxidized vegetable oils replace phthalate esters?
- According to the researches in the last 18 years, epoxidized vegetable oils are one of the alternatives that are strongly encouraged to substitute phthalate esters since they were proven to be valid in various applications, eco-friendly and sustainable resource.
