DuPont™ 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® resin adds permanent flexibility to the PVC compound, enabling higher-value use in more demanding applications such as weather-exposed roofing and environmental protection membranes.
PVC plasticizer extraction issues, from PVC weathering or exposure to chemicals, can be reduced by using a polymer such as Elvaloy® that locks itself into the flexibilized compound. Elvaloy® performance helps increase the compound’s acceptance of other performance additives such as flame retardants, fillers and stabilizers.
Elvaloy® flexible PVC plasticizer applications include single-ply roofing, geo-membranes, cable jacketing compounds, and “no-dig” fold-and-form pipe liners.
