Westlake ELEVATE™ EF528AA is an ethylene vinyl acetate copolymer with 18.5% VA. EF528AA is designed for blown and cast films requiring excellent optics and low heat seal initiation. High melt strength makes EF528AA 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 Note: *AA formulation contains no slip and no antiblock. |
