Synthesis of novel plasticizer ester end-capped oligomeric
Furthermore, compared with ATBC and DOTP, EOLs showed better migration resistance in the leaching test. All test results showed that the comprehensive performance of EOLs was better than those of commercial green plasticizers ATBC and DOTP, which provided a new method for the development of novel green plasticizers.
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
Plasticizers: Synthesis of phthalate esters via FeCl3
Plasticizers are extensively used in manufacturing of plastic materials, textiles, paints, cosmetics, etc. Phthalate esters are used to prepare in harsh conditions, at a higher reaction temperature. FeCl 3-catalyzed esterification of alcohols with phthalic anhydride affords phthalate esters, under mild conditions.
Current Status of Plasticizer Research | SpringerLink
Compared with phthalate esters, hexahydrophthalate esters have lower densities and viscosities for use as plasticizers, which can improve the low-temperature softness of plastics, while other properties such as Shore hardness and mechanical strength.
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
- 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 has the best mechanical properties?
- Of the plasticizers we synthesized, the best film mechanical properties were provided by OC plasticizer, containing primarily propylene glycol monoacetate, but also propylene glycol diacetate, acetic acid and propylene glycol in its mixture.
- What are the chemical properties of plasticizers?
- The chemical properties, such as acid value, iodine value, saponification value, ester value and water content were determinated for the plasticizers and are shown in Table 2. This values provide an additional confirmation for the occurrence of esterification and epoxidation reactions, respectively.
- 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.
