Designing anti-migration furan-based plasticizers and their
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 PVC. Meanwhile, the introduction of ether and ester group can reduce the melting point of FDCA esters and help to improve flexibility, oil resistance.
Thermal degradation of esters/ethers derived from tartaric
The most obvious reason is that it is an effective plasticizer for a variety of polymers [ 8 – 10, 16 ]. It is derived from two low-value materials, o -xylene and butyraldehyde. o -Xylene is the least valuable of the mixed xylenes and may be readily oxidized to phthalic acid.
Plasticizer
Ester plasticizers are selected based upon cost-performance evaluation. The rubber compounder must evaluate ester plasticizers for compatibility, processibility, permanence and other performance properties.
DEVELOPMENT OF NEXT-GENERATION ESTER PLASTICIZERS FOR HIGH
In the first part of this study, four plasticizers were evaluated along with a control compound d without plasticizer: TegMeR 812 - lower MW polyether ester RX-14434 - higher MW polyether ester RX-14562 - medium MW aliphatic polyester RX-14565 - aromatic polyether ester TegMeR 812 and RX-14434 have similar structures,
- 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.
- 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.
- 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.
- 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.
- Do polar elastomers use glycol ether alcohols?
- As polarity is important to the application of ester plasticizers and the application to polar elastomers, it is necessary to note that some of the AAA types use glycol ether alcohols. The presence of the oxygen atoms of the glycol ether alcohols causes higher polarity than occurs with common (carbon only) alcohols.
