Four plasticizers were evaluated along with a control compound without plasticizer: TegMeR 812: lower MW polyether ester RX-14434: higher MW polyether ester RX-14562: aliphatic polyester
These plasticizers are sometimes volatile and have fairly high specific gravity. They are powerful solvents because of ester and ether groups. They are useful in nitrile rubber, chloroprene

The structure of these furan-based plasticizers contain furan ring, ether and ester groups. The introduction of furan ring helps plasticizers improve compatibility with the polar
The studied plasticizers in most cases exhibited leaching resistance like DOTP; however, in hexane this resistance was much better than for DOTP. This observation could be explained by the strong non-polar behaviour of hexane

Selection of ester plasticizer Ester plasticizers find significant use in nitrile, polychloroprene and chlorosulfonated polyethylene elastomers that are used at temperatures of 135°C maximum.
Plasticizers play an important role in polymer processing. This is particularly true for PVC, which may require 40%–60% plasticizer by weight for processing and use [1].PVC is

- What are ester plasticizers?
- This paper discusses ester plasticizers, one of the more common and important plasticizer classes. Plasticizers are polymer modifiers, as are all the other ingredients included for the formation of an elastomer compound. Plasticizers may be thought of according to their function in a compound or by their type.
- Do fluorocarbon elastomers accept ester plasticizers?
- Fluorocarbon elastomers will accept a relatively wide range of ester plasticizers, but here, with both the high temperature post cure and application temperatures ranging to 232°C, they find use only at very low levels for processing. The selection of an ester plasticizer can often be confusing because of the large choice available.
- Which plasticizers are used in combination with specialty monomeric esters?
- Flame-retardant plasticizers, phosphate esters and chlorinated paraffins are often combined in usage with flame-retardant plasticizers frequently used in combination with specialty monomeric esters. Both materials are inefficient plasticizers, thus explaining their combinations with specialty monomerics.
- Can polymeric esters enhance a high-performance elastomer?
- Polymeric esters are especially suited for high-performance elastomers such as nitrile, chlorosulfonated polyethylene, high saturated nitrile, polyacrylates, acrylics and nonpost-cured fluoroelastomers. An example of how polymeric esters can enhance a high-performance elastomer is depicted in Figure 8.
- Are polymeric polyesters a monomeric ester?
- Polymeric polyesters are subject to the same trends as monomeric esters as relates to structure, polarity and molecular weight. Generally, viscosity is referenced in place of molecular weight of polymeric plasticizers. The higher the viscosity, the greater the permanence.
- Are esters solvents for amorphous polymers?
- Under suitable conditions, esters are solvents for amorphous polymers, that is, the polymer would eventually dissolve in the plasticizer. With crystalline or semi-crystalline polymers, some plasticizers may enter the crystalline (ordered) and the amorphous (disordered) regions.
