Plasticizers: Types, Uses, Classification, Selection & Regulation
Ring Saturated Variants of Phthalate Esters (e.g. DINCH) Plasticizers like DINCH (di-isononyl ester of cyclohexane-1,2-dioc acid) are valued as phthalate look alikes without (proven) adverse effects on human health. They have relatively low solvating strength for PVC and compatibility with PVC is defensive to that of their phthalate analogs.

Overall, global plasticizer consumption will grow at a rate of about 3.5% per year in the next few years. Phthalate esters, based on phthalic acid, are the main types of plasticizers used since they satisfy a broad range of processing and performance requirements, as well as a large number of markets.
Phthalate Ester - an overview | ScienceDirect Topics
Phthalate acid esters (PAEs) are a class of chemical compounds widely used in different industrial applications, mainly as plasticizers for polyvinyl chloride (PVC) resins, adhesives and cellulose film coatings and with minor applications in cosmetics, medical products and insecticide carriers.
Phthalic anhydride
The primary use of phthalic anhydride is a precursor to phthalate esters, used as plasticizers in vinyl chloride. Phthalate esters are derived from phthalic anhydride by the alcoholysis reaction. In the 1980s, approximately 6.5 million tonnes of these esters were produced annually, and the scale of production was increasing each year, all from

Recently, epoxidized vegetable oil 13,14, polymer plasticizer 13,15, polyol ester 16,17 and phosphate plasticizer 14 have been reported as alternative plasticizers, which suppresses the migration
- 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.
- What is an ester plasticizer?
- An ester plasticizer, in its simplest concept, is a high-boiling organic solvent that when added to an elastomeric polymer reduces stiffness and permits easier processing.1 For general performance applications, compounders require moderate performance in several areas without particular emphasis on any one.
- 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 factors affect Plasticizer-elastomer interaction?
- Plasticizer–elastomer interaction is governed by many factors, such as solubility parameter, molecular weight and chemical structure. Ester plasticizers are selected based upon cost/performance evaluation. The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties.
- Are plasticizers suitable for elastomers and high-temperature polymers?
- Plasticizers commonly used for the traditional and the high-temperature polymers are extractable, incompatible or too volatile. This paper provides information on plasticizers that are designed for traditional elastomers and high-performance polymers.
- What is a good plasticizer for high-heat nitrile (HNBR)?
- High-saturated nitrile is used in many high-heat applications. The use of 8-10 trimellitate is well documented as the plasticizer of choice for HNBR. As the graph depicts, a phthalate/adipate polymeric ester with a molecular weight of 1000 will enhance long-term heat aging properties. Fig. 3. Heat resistance of plasticized HNBR compounds
