Borealis RG435MO Polypropylene, Transparent Random Copolymer  (discontinued **)
Categories: Polymer; Thermoplastic; Polypropylene (PP); Polypropylene Copolymer

Material Notes: RG435MO is a specially modified highly-transparent polypropylene random copolymer with medium melt flow rate. Products molded from this grade exhibit excellent transparency, good gloss, high impact strength at ambient temperature, relatively high stiffness and good demolding and antistatic properties. These properties, together with high gloss, make this grade excellent choice for household and packaging articles. Applications: transparent packaging where high impact is needed (i.e. pails), houseware containers, food packaging, sweet-boxes, caps and closures, and lids.
