Selected Fatty Acids Esters as Potential PHB-V
However, it seems that this amount of free fatty acids is still relatively low and shouldn’t affect the efficiency of this ester as a plasticizer. Ester 1 similarly to ester 4 is characterized by higher than other esters iodine value, respectively 77.6 g I 2 /100 g and 75.7 g I 2 /100 g, cause both of them were obtained by oleic acid
Combining Renewable Eleostearic Acid and Eugenol to
In this study, two kinds of sustainable plasticizers (eleostearic acid eugenol ester (EAEE) and epoxidized EAEE) were synthesized to plasticize PVC films using eleostearic acid and eugenol. Compared to EAEE, PVC plasticized with epoxidized EAEE showed more flexible and thermal stability.
Biobased Plasticizers from Tartaric Acid
The results showed that all these TA esters exhibit good plasticizing performance. At a concentration of 30 phr in PVC, the best results for the plasticizing effect, in terms of glass...
Chlorinated Ester Plasticizers - ResearchGate
Stabilized chlorinated esters (CEs), specifically those derived from esters of palm kernel, palm, and coconut oils, act as viable replacements for chlorinated paraffins (CPs) as secondary...
Plasticizers: Types, Uses, Classification, Selection & Regulation
There are two main groups of external plasticizers: A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
- 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.
- Which plasticizer is most stable after 10 d?
- After 10 d, the migration trend of all samples had been stabled, it showed that the traditional plasticizer like DOP, DOTP and DOA had basically move out from the PVC matrix in non-polar environment due to their own single structure, while the PVC plasticized with A-ODL showed the best stability in all the environment.
- Which plasticizer is best for acrylic elastomers?
- Table V highlights data from this study conducted by DuPont Dow Elastomers L.L.C. ®. DBEEEG, a high molecular weight glycol ether ester monomeric plasticizer, is commonly recommended for acrylic elastomers. In this study, A-1000A and A-1000B show they are equal or better than DBEEEG at softening efficiency and original low temperature.
- 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.
