Westlake ELEVATE™ EF529 18.5% Ethylene Vinyl Acetate Copolymer
Categories:	Polymer; Thermoplastic; Ethylene Vinyl Acetate
Material Notes:	Westlake ELEVATE™ EF529 is an ethylene vinyl acetate copolymer with 18.5% VA. It contains no slip or antiblock and is designed for blown and cast films requiring excellent optics and low heat seal initiation. High melt strength makes EF529AA an excellent choice for profile extrusions, molding, and foaming applications requiring medium VA content. Application/Uses Flexible packaging films Peelable seals, adhesive layers Injection and blow molding Hot melt adhesives and blends Profile extrusions, tubing, wire & cable This resin grade complies with 21 CFR, section 177.1350.
Key Words:	Excellent optics and low heat seal initiation. 18.5% EVA.
