A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Phthalate esters are still the most powerful plasticizers and dominate the plasticizer market due to their great plasticizing effect and low-cost, although phthalate plasticizers can migrate to
Synthesis of novel plasticizer ester end-capped oligomeric
In this work, a novel high efficiency plasticizer, an ester-capped oligomeric lactic acid mixture (EOL), was successfully synthesized by a two-step esterification reaction, with L -lactic acid as the main raw material. The structure of EOL was characterized by using FT-IR, 1 H NMR and time of flight mass spectrometry (TOF-MS).
Method 606: Phthalate Ester - US EPA
It is particularly important to avoid the use of plastics because phthalates are commonly used as plasticizers and are easily extracted from plastic materials. Serious phthalate contamination can result at any time, if consistent quality control is not practiced. Great care must be experienced to prevent such contamination.
Selected Fatty Acids Esters as Potential PHB-V
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHB-V) has not been used for demanding technical applications yet due to its limited mechanical properties, particularly its high brittleness. An appropriate route to overcome these limitations is the implementation of plasticizers in the PHB-V matrix via compounding. In this paper the use of different types of fatty acids esters as PHB-V
A review of organophosphate flame retardants and plasticizers
Organophosphate esters (OPEs) are used as additives in flame retardants and plasticizers. Due to phase out of several congeners of polybrominated diphenyl ethers (PBDEs), the application of organophosphorus flame retardants (OPFRs) is continuously increasing over the years. As a consequence, large amounts of OPEs enter the environment.
- 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 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.
- 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.
