Polyglycerol esters demonstrate superior antifogging
The excellent antifogging properties of polyglycerol esters are due to their controlled migration rate in the polymer, their optimum surface-active properties, their high thermal stability, and their compatibility with various polymers and additives.
Structure Design, Performance Simulation and Plasticizing
Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved. In this paper, a variety of copolyesters are designed and synthesized from succinic acid, hexanediol and other four different diols
reg
primary plasticizer for polyvinyl chloride and copolymer resins. Palatinol 911P offers excellent permanence, low volatility, good efficiency and good retention of physical properties for heat aging vinyl applications. Heat and light stability of Palatinol 911P is superior to phthalate esters made from branched chain alcohols.

Bioplasticizer - an overview | ScienceDirect Topics
According to Stuart, diesters of succinic acid (derived from a biobase) are an underestimated substitute for phthalate plasticizers. Succinates with longer alkoxy chains (dioctyl succinate and dihexyl succinate) were shown to be more efficient than dioctyl phtalate in plasticizing PVC on a mass percent basis [63].
- How to choose a high-performance ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer. 1.
- What is a general performance ester plasticizer?
- Some general performance ester plasticizers used in the marketplace today are DOA, DIDA, DIDP, DOP, DINP and other phthalates and adipates made from straight-chain alcohols of 7–11 carbons in length. Ester plasticizers are commonly used only for their as-molded, low-temperature contribution.
- How are ester plasticizers selected?
- Ester plasticizers are selected based upon cost/performance evaluation. The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer.
- Why do polyglycerol esters have antifogging properties?
- As with many other antifogging agents, polyglycerol esters also have antistatic properties because the water film that forms on the polymer surface reduces its resistivity. Polyglycerols as such (not esterified) are used as plasticizers in starch based biodegradable thermoplastic compositions.
- Does epoxidized fatty acid tri-esters bio-plasticizer reduce efame?
- Governed by the interplay between two extra polar, PVC-compatible short esters and higher molecular weight relative to ordinary EFAME, the fogging value of the resulting epoxidized fatty acid tri-esters bio-plasticizer was found to reduce to a level comparable to DIDP.
- Do plasticizers have a low fogging value?
- In the case of PVC artificial leather, plasticizers make up the vast majority proportion of volatile substances; therefore, the automobile industry calls for plasticizers with extremely low volatility, or specifically, a low fogging value. Among all commercial bio-plasticizers, few can fulfil this requirement as well as DIDP.
