Borealis HH315MO Polypropylene (discontinued **)
Categories:	Polymer; Thermoplastic; Polypropylene (PP)
Material Notes:	HH315MO is a polypropylene homopolymer intended for injection molding. Its high melt flow makes it especially suitable for products with long flow length. This grade is designed for high-speed injection molding and contains nucleating, antistatic and slip additives. This polymer is a CR (controlled rheology) grade with narrow molecular weight distribution giving low warpage. Products originating from this grade have excellent demolding properties, very high stiffness, good transparency and gloss and good impact strength at ambient temperatures. Applications: thin wall containers, square containers, rectangular and flat products like lids and trays, caps and closures, and products with thicker wall sections requiring short cycle time.
