Plasticizers: Types, Uses, Classification, Selection & Regulation
Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates. They are made from aliphatic dibasic acids such as adipic acid and alcohols.

Specialty Plasticizers for Rubber/Elastomers | Hallstar
High ACN polymers require high polarity plasticizers, low ACN polymers require low polarity plasticizers. Polymerics used at greater than 15 PPHR are generally used in combinations with monomerics. Hallstar has a wide range of monomeric and polymeric plasticizers that can be used with NBR. APPLICATIONS

polymer backbone. It is important to point out that be-cause of the high acrylic monomer con-tent, both types of acrylic elastomers are fairly polar. Thus, the use of higher po-larity ester plasticizers is critical to as-sure optimal compatibility and com-pound performance. Because of high temperature post-cure required by most acrylic elastomers
Bioplasticizer - an overview | ScienceDirect Topics
In the mid-1970s, Hercules Chemical Company introduced two polyol ester plasticizers, Hercoflex 600 and Hercoflex 707. These plasticizers were prepared by the esterification of pentaerythritol and dipentaerythritol with a mixture of short-chain acids, predominately C6 acid.
- What is a polymeric plasticizer?
- Polymeric polyester plasticizers may be used in higher-performance applications where superior plasticizer non-volatility and fluid chemical extraction resistance are critical. Polymeric plasticizers are produced by reacting a dibasic carboxylic acid with a glycol or a mixture of different dibasic glycols.
- 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.
- 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.
- Can polymeric esters enhance a high-performance elastomer?
- One example of how polymeric esters can enhance a high-performance elastomer is depicted in Figure 3. 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.
- 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.
- Which elastomers use polymeric esters?
- Polymeric esters are especially suited for high performance elastomers, such as nitrile, high saturated nitrile and polyacrylates. Polymeric esters also have found utility in chlorinated polyethylene, chlorosulfonated polyethylene and fluoroelastomers.
