| 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 this material 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 Profile extrusions, tubing, wire & cable&& |
