Westlake EF532 12% EVA Copolymer (Experimental Product)

Westlake EF532 resin is a 12.0% EVA copolymer designed for use as a sealant / lamination layer in monolayer or coextruded flexible film structures. It has very low seal initiation temperature, excellent film optics, and outstanding film toughness, especially at low temperatures. It comes with AA (no slip, no antiblock) or XL (very high slip, medium antiblock) additive packages. Its applications include low temperature sealant resin for flexible packaging and lamination film. This resin grade complies with 21 CFR 177.1350. It is also Kosher compliant. EF532 can be extruded in conventional equipment designed for PE. Corrosion-protected elements, especially dies, are recommended. The maximum recommended melt temperature is 425° F because EVA resins can thermally degrade at higher extrusion temperatures.
