ELVALOY Copolymer Alloys | Plastics Modification | Dow Inc.
ELVALOY is a flexible polymer that is highly miscible with PVC during the PVC compounding stage. This makes it a useful PVC plasticizer. Because it is a high-molecular-weight, solids-phase (non-liquid) PVC plasticizer, ELVALOY adds permanent flexibility to the PVC compound, enabling higher-value use in more demanding applications.
PARAPLEX A-8000 | Hallstar Industrial
Used In PARAPLEX A-8000 is a low molecular weight polymeric ester. PARAPLEX A-8000 offers the best low-temperature performance when compared to other polymeric plasticizers. PARAPLEX A-8000 also offers better permanence, volatility and migration resistance than monomeric plasticizers.
Eastman Product Finder | Product Catalog | Specialty Materials
Eastman Cellulose Acetate CA-398-30 is a high-viscosity, high molecular weight cellulose acetate supplied as fine, dry, free-flowing powder. Its relatively uniform particle size permits good plasticizer distribution during blending and it offers good physical properties for molded and extruded articles.
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.

are monomeric plasticizers. Polymeric plasticizers are resistant to extraction by solvents, oils and fluids, and they resist migration to other polymer compounds in contact with the PVC material. In short, polymeric plasticizers provide greater permanence than monomerics. Polymeric and monomeric ester plasticizers can often be blended together.
- 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.
- 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.
- 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.
- 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.
