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.

Jayflex DTDP plasticizer is the highest-molecular-weight phthalate plasticizer, providing greater performance at high temperatures. It is the preferred plasticizer for automotive cable applications and THHN/NMB electrical wire insulation. Learn more Linear plasticizers
Quantification of five plasticizers used in PVC tubing through high
After extraction from PVC tubes by diluting with THF and precipitating PVC with ethanol, the plasticizers were quantified by GC–MS with high sensitivity (LOD between 0.06 and 0.25 μg/mL and LOQ between 0.01 and 2.0 μg/mL, depending on the plasticizer).
Influence of Polyol Plasticizers on the Properties
In this work, high-alcoholysis polyvinyl alcohol (PVA) films were fabricated by melt processing and the plasticizing effect of compound polyol plasticizers on PVA were investigated with X-ray diffraction (XRD), differential scanning calorimetry (DSC), rheological measurements, mechanical tests etc. Hydrogen bonding interactions occurred between PVA and plasticizer. With the increase of
Superplasticizer
Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers retard the curing of concrete. [1]
- 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.
- 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.
- 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.
- 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.
- Which plasticizer is best for HNBR?
- The use of 8-10 trimellitate is well documented as the plasticizer of choice for HNBR. As the graph depicts, a phthalate/adipate polymeric ester with a molecular weight of 1000 will enhance long-term heat aging properties. Fig. 3. Heat resistance of plasticized HNBR compounds Many plasticizers have been evaluated in HNBR for compatibility.
