The Plastics Group: New source of filled PP for sheet
Custom compounder and recycler The Plastics Group (TPG) of Woonsocket, USA, is expanding its Polyfil product line into extrusion and blow molding markets, with an initial focus on polypropylene compounds. Sheet extrusion and thermoforming for microwavable food containers are targets for three new talc-filled (20%, 30%, and 40%) homopolymers with MFRs of 0.4 to 2.0. Impact-modified versions have low-temperature toughness for use in frozen-food packaging. Another new area is large-part blow molding. New 20% and 30% glass-reinforced PP impact copolymers have been introduced for applications from water tanks to automotive seat backs and fan shrouds.
