Borealis RE420MO Polypropylene Random Copolymer, Transparent
Categories:	Polymer; Thermoplastic; Polypropylene (PP); Polypropylene Copolymer
Material Notes:	RE420MO is a specially modified highly-transparent polypropylene random copolymer with medium melt flow rate. This grade is intended for injection molding and stretch blow molding. and is designed for high-speed injection molding and contains nucleating and demolding additives. Products originating from this grade have excellent transparency, very good organoleptic properties, good balance of stiffness and impact strength at ambient temperature, low blooming and good demolding properties. Applications: excellent transparency, lids, pails, closures, sweet-boxes, bottles, and houseware containers. Information provided by Borealis AG
