| ELVALOY 742 |
 |
ELVALOY 741 and 742 are designed to improve the quality and extend the useful lifg of articles fabricated from polyvinyl chloride (PVC) compounds.
Unlike conventional plasticizers, ELVALOY resin modifiers do not migrate through the compound to its surface and therefore are not lost through evaporation or extraction.
ELVALOY resin modifiers are substantially higher in molecular weight than conventional polymeric plasticizers and therefore offer the utmost in permanence.
ELVALOY is compatible with PVC and other plasticizers so that compounds can be formulated to vary hand, drape, and texture. Blending ELVALOY with selected plasticizers and fillers results in a range of properties including soft, dry, leathery textures and rubberlike materials at relatively low cost.
ELVALOY resin modifiers enhance the performance of vinyl compounds by providing: , low extraction in soapy water, hexane, and mineral oil , low volatility, migration, and spew , high strength , oustanding low temperature impact resistance , excellent resistance to micro-biological attack |
