NEW POLYMERIC ESTERS FOR LOW POLARITY ELASTOMERS - ResearchGate
Currently, plasticizers for these low polarity elastomers are limited to inexpensive process oils, including napthentic, paraffinic, and other petroleum-based products, and low molecular weight...
Plasticizers: Types, Uses, Classification, Selection & Regulation
Due to its low cost and generally good performance, DEHP is widely employed as a plasticizer in manufacturing articles made of PVC. Melting point: 50°C Boiling point: 250 - 257°C at 0.5 kPa Structure of DEHP DEHP offers good gelling, satisfactory electrical properties and helps to produce highly elastic compounds with reasonable cold strength.
Research progress of novel bio-based plasticizers and their
Abstract Plasticized polyvinyl chloride (PVC) has been widely used in the world. Petroleum-based plasticizers especially phthalates have been the most common plasticizers used in PVC. However, the global petroleum resources are becoming scarce gradually, and the hygienic requirements for plasticizers are increasing. Owing to the negative impact of petroleum-based plasticizers on human health
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
Thermal degradation of esters/ethers derived from tartaric acid
The ideal plasticizer should be low in cost, display good compatibility with the polymeric substrate and exhibit resistance to temperature change or chemical extraction [3, 8, 14, 15]. One of the most well-established plasticizers has been di-(2-ethylhexyl)phthalate (DEHP or DOP) [8–10, 16].
- What is a polymeric plasticizer?
- Polymeric polyester plasticizers may be used in higher-performance applications where superior plasticizer non-volatility and fluid chemical extraction resistance are critical. Polymeric plasticizers are produced by reacting a dibasic carboxylic acid with a glycol or a mixture of different dibasic glycols.
- 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.
- Which polymeric plasticizer is best for acrylics?
- Polymeric plasticizers that are efficient in lowering hardness, provide good low-temperature properties and have low volatility in both post-cure and heat aging are ideal candidates for acrylics. Two polymeric plasticizers that meet these requirements are polyester adipates with a molecular weight of 1000.
- 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 a standard monomeric plasticizer?
- he following:Standard Monomericsare typically low molecular weight, general purpose products offering a good balance of performance properties for on-critical end use applications. These plasticizers generally fall under our Plasthall® trade name, suc
- 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.
