Material overview
This is extra-clean, natural (uncolored) regrind of a low-melt-flow polypropylene random copolymer from a single source. Resin in this melt flow range is commonly used in blow molding, sheet and profile extrusion, and thermoforming.
Published data for the source resin shows a flexural modulus of 141,000 psi (1% secant, 1.3 mm/min), notched Izod impact of 1.3 ft-lb/in at 23 °C and a deflection temperature of 179 °F at 66 psi. Regrind properties can differ from the original resin, so buyers should qualify the material for their process.
