Material Notes:
Westlake ELEVATE™ EF522 is an ethylene vinyl acetate copolymer with 12% VA. EF522 is designed for blown and cast films requiring excellent optics and low heat seal initiation. High melt strength makes EF524 an excellent choice for profile extrusions, molding, and foaming applications requiring medium VA content..Application/UsesFlexible packaging filmsPeelable seals, adhesive layersInjection and blow moldingProfile extrusions, tubing, wire & cableThis resin grade complies with 21 CFR, section 177.1350.
