Hallstar | Innovative, leading-edge, ester chemistry solutions
New Innovations New polymeric esters from Hallstar have been specifically designed to be highly compatible with low ACN (H)NBR, EPDM, TPV, TPO, PE and PP polymer compounds. The polymeric nature increases modifier permanence without sacrificing low temperature and general mechanical performance.
A potentially general approach to aliphatic ester-derived PVC
As sustainable alternatives, aliphatic ester-derived plasticizers feature low cytotoxicity, biodegradability, and renewability, but they can only partially replace DEHP in PVC formulations because they have a strong tendency to migrate.

Research progress of novel bio-based plasticizers and their
Many bio-based PVC plasticizers, such as vegetable oil-based plasticizers, cardanol-based plasticizers, lactic acid-based plasticizers, waste cooking oil-based plasticizers, polyester plasticizers, hyperbranched plasticizers and so on, have been extensively studied.
Bio-Based Plasticizers for Polyvinylchloride (PVC) | SpringerLink
The conventional petroleum-derived plasticizers used in many flexible PVC products are phthalate esters (also known as “phthalates”). The literature reported that phthalates represent more than 85% of world plasticizers production, of which 90% is annually used in PVC manufacturing [ 6 ].
- Is PVC a good plasticizer?
- Thermal stability studies showed that PVC blends with HPGs were more stable (exhibiting higher onset temperature values on TGA curves) than samples with DEHP. A great number of ether and ester groups in a plasticizer molecule provide donor-acceptor interactions with PVC, resulting in an excellent migration resistance.
- What plasticizers are used for PVC?
- Some of the most common plasticizers that are currently being utilized for PVC are aromatics and aliphatic esters, typically di (2-ethylhexyl) phthalate (DEHP) and dioctyl adipate (DOA). There have been concerns over the use of DEHP, as it negatively impacts human health and the environment .
- Why do plasticizers use ester based polymers?
- In PVC and PLA, the polarity of the polymers is similar to that of esters, which is why ester-based plasticizers are quite commonly used with these polymers . A sufficiently long carbon alkyl chain attached to the central ester structure disrupt the intermolecular forces between the polymer chains, as the alkyl chain is nonpolar.
- Which plasticizer has the best plasticizing effect on PVC and PLA films?
- According to the above Tg results of plasticized PVC and PLA films, the AcMAE-C6 plasticizer exhibited the best plasticizing effect on PLA films as well as PVC films, and this phenomenon seems to be due to the structure of AcMAE-C6 having the best compatibility with both PVC and PLA.
- Which plasticizer is best for PVC film elongation?
- By comparing the percent elongation of PVC films containing different plasticizer types, AcMAE-C6 is found to be the most effective plasticizer (780%), followed by AcMAE-C8 (757%), AcMAE-iC8 (729%), AcMAE-iC13 (595%), and AcMAE-C4 (477%).
- Why is PVC compounded with plasticizers?
- Thus, it is often compounded with plasticizers to enhance its flexibility and toughness for various applications. Some of the most common plasticizers that are currently being utilized for PVC are aromatics and aliphatic esters, typically di (2-ethylhexyl) phthalate (DEHP) and dioctyl adipate (DOA).
