Westlake Epolene® E-43 Chemically Modified Polypropylene, Maleation Processed
Categories:	Polymer; Thermoplastic; Polypropylene (PP)
Material Notes:	Product Description: Epolene E-43 is a maleic anhydride grafted polypropylene recommended as a coupling agent for polypropylene (PP) composites and for providing slip resistance in floor finish emulsions. Because of the polarity and anhydride functionality, Epolene E-43 is useful for laminating, as a compatibilizer for PP blends with nylon or EVOH, and for enhancing the strength of composites that utilize reinforcements / fillers such as glass, talc, calcium carbonate, and metals. Key Attributes: Coupling agent and compatibilizer for PP composites and alloys Excellent pigment dispersion ai Maleic anhydride grafted polypropylene (PP) Provides slip resistance in floor polish finishes Useful in adhesive blends Application/Uses: Automotive Bookbinding Building and Construction Caulks and Sealants Hot Melt Adhesives Laminating Solventborne Adhesives Waterborne Adhesives
