ELEVATE™ EF524

Westlake ELEVATE™ EF524 is an ethylene vinyl acetate copolymer with 14.5% VA. EF524 is designed for blown and cast filmsrequiring excellent optics and low heat seal initiation. High melt strength makes EF524 an excellent choice for profile extrusions, molding, and foaming applications requiring high VA content.

Application/Uses:
Flexible packaging films
Peelable seals, adhesive layers
Injection and blow molding
Profile extrusions, tubing, wire & cable
