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.
Innovative processes allow cyclical tyre production and reuse
Such products include new tyres, but also high-end industrial components such as engine mounts and vibration isolators. The REW-TYRES team also demonstrated the processes’ suitability for making consumer products such as shoes and shoe soles, watch bands and numerous others. The project has patented both processes and its technology.

- How do I Choose an ester plasticizer?
- A610), can be found on pages 7-8.When selecting an ester plasticizer, it is important to consider which elastomer is being used and the properties of that elastomer. Plasticizers and elastomers need to be compatible with each other b
- 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.
- What elastomer needs to be cured?
- 150°C for intermittent service. The elastomer requires antioxidants, antiozonants, fungicides, plasticizers, tackifiers and flame retardants as the occasion and se erity of the application demands. It can be cure with sulfur or peroxide systems. High-ACN polymers require high-polarity plasticizers, low-ACN polymers
- 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.
- 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.
- Are elastomer plasticizers good for rubber?
- Traditional elastomer polymers, such as nitrile, polychloroprene, chlorinated polyethylene and chlorosulfonated polyethylene, have for years used moderate- to low-performance ester plasticizers. However, longevity requirements for rubber articles made from these elastomers have created a need for higher-performance ester plasticizers.
