Polyvel shared expertise and experience of upgrading recycled plastics, with Madeline Daecher and Dean Dodaro. pinfa North America webinar. Polyvel, is a US-based extrusion compounder specialised in additive masterbatches and custom formulations, delivering pellets...
Post-consumer bottle PET was one-step recycled to c. 2 nm functionalised carbon spheres, tested as PIN FR in PBT. The PET was shredded, cleaned and dried, then reacted with ethanolamine (1500 g PET to 975 ml MEA) at 280°C for 18 hours (pyrolysis). Resulting sold was...
An intumescent phosphorus-nitrogen PIN FR showed to be effective in both virgin and re-extruded PP (UL 94 V-0 3.2mm). Recycled PP was lab simulated by eight times re-extrusion at 210°C, so without any other polymers or contaminants likely to be found in real secondary...
