W&W HDPE Regrind — 0.10 MI Fractional Melt
High-density polyethylene, fractional melt: extra-clean natural regrind
W&W Material Supply of Belding, Michigan, offers extra-clean natural fractional-melt HDPE regrind from a single source. The source resin is rated at 0.10 g/10 min melt index (190 °C / 2.16 kg) and 0.944 g/cm³ density, and the stream offers approximately 2–3 truckloads of recurring monthly volume.

Material overview
This is extra-clean, natural (uncolored) regrind of a fractional-melt HDPE from a single source. A single-source stream gives buyers a known origin month to month, rather than a mixed stream from many plants.
Published data for the source resin shows a very low melt index and a high-load melt index of 8.3 g/10 min, with slow-crack-growth (PENT) of 200 hours at 80 °C, a brittleness temperature below −100 °C and notched Izod impact of 4.0 ft-lb/in: properties associated with melt strength and toughness in extrusion. Clean natural regrind of this type is commonly considered for blending with virgin fractional-melt HDPE. Regrind properties can differ from the original resin, so buyers should qualify the material for their process.
Doug can walk you through the available data and what lot-specific information can be provided before you commit to a load.
