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.
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).
Structure Design, Performance Simulation and Plasticizing
Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved. In this paper, a variety of copolyesters are designed and synthesized from succinic acid, hexanediol and other four different diols
18 Technical Ester plasticizers for high-temp AEM elastomers
Ester plasticizers for high-temp AEM elastomers Acrylic elastomers are used in applica-tions requiring continuous service up to 175°C and intermittent exposure to ex-tremely high temperatures of up to 200°C. 1 the past year, These elastomers are considered lower-cost alternatives to other high-temperature elastomers, such as fluoroelastomers
DEVELOPMENT OF NEXT-GENERATION ESTER PLASTICIZERS FOR HIGH
of plasticizer while maintaining Shore A hardness by changing the polymer ratio. The larger quantity of plasticizer helps to emphasize and differentiate performance between different plasticizer compounds. Therefore, for the second part of our study the following formulation was adopted: Material Wt (phr) % in the formula Vamac Ultra IP a 36
- 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.
- 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.
- Are epoxidized cardanol ester stabilizers suitable for PVC films?
- In this work, two different epoxidized cardanol ester stabilizers were synthesized, and their structures were characterized. Moreover, their synergistic plasticizing and thermal stabilization effects on PVC were studied, and PVC films with excellent mechanical and thermal stability were prepared.
- 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 organic heat stabilizers suitable for PVC?
- In recent years, environmentally friendly organic heat stabilizers have been prepared and developed for the heat stability of PVC. Wang et al. [ 8] studied tung-oil-derived imide epoxidized esters as a PVC heat stabilizer.
