Carmel Olefins CARMELCLEAR™ ME 74 E Specialty Polypropylene (discontinued **)
Categories:	Polymer; Thermoplastic; Polypropylene (PP); Polypropylene Copolymer; Polypropylene, Impact Modified; Molded/Extruded
Material Notes:	CARMELCLEAR™ ME 74 E is a modified random polypropylene copolymer developed for extrusion of high impact transparent articles. It exhibits excellent impact resistance at low and ambient temperatures, very good transparency combined with good flexibility, low stress-whitening, and soft touch. APPLICATIONS CARMELCLEAR™ ME 74 E is suitable for flexible high-impact sheets, flexible lids with tight closure properties, films with low haze. Frequently it is used as impact modifier in blends with random copolymers.
