STARTUP & SHUTDOWN RECOMMENDATIONS Purge Compound HDPE or HIPS Recycling Recycling Stat-Tech up to 20% is permissible. Testing the application is highly recommended to determine the effect recycling has on the desired physical properties. Venting • Place vents at the end of fill and anywhere potential knit/weld lines will occur. • All vents need to be vented to atmosphere. • For circular parts, full perimeter venting is recommended. • Cut vent depths to: - PC Compounds: 0.001"–0.002" depth and 0.250" width - PC/PSU Compounds: 0.002"–0.003" depth and 0.250" width - PES Compounds: 0.003"–0.004" depth and 0.250" width - PEI Compounds: 0.001"–0.003" depth and 0.250" width - PP Compounds: 0.001"–0.002" depth and 0.250" width - ABS Compounds: 0.0015"–0.0025" depth and 0.250" width - PEEK Compounds: 0.002"–0.004" depth and 0.250" width - Nylon Compounds: 0.002" min. depth and 0.250" width • Increase vent depth to 0.040" (1.0mm) at 0.250" (4.0mm) away from the cavity and vent to atmosphere.

Recycle Solutions Gravi-Tech™ REC Recycled Formulations Remafin™ Fiber Colorants for PP

Avient’s new reSound™ REC thermoplastic elastomers (TPEs) incorporate recycled content from polyvinyl butyral (PVB) recycled from broken vehicle windshields and laminated architectural glass to support a circular economy. They can be injection molded or overmolded onto polypropylene (PP). Unique technologies that improve the recyclability of products and enable recycled content to be incorporated, thus advancing a more circular economy

Based on polymers such as polypropylene (PP), the new formulations also include a natural filler made from renewable plant sources that would otherwise go to waste. reSound™ R recycled content thermoplastic elastomers (TPEs): Developed to help brand owners create more sustainable end-user products, these formulations utilize 9 to 83 percent recycled content from post-consumer recycled (PCR) and post-industrial recycled (PIR) sources. Unique technologies that improve the recyclability of products and enable recycled content to be incorporated, thus advancing a more circular economy

NEW Cesa™ Unify™ A4R - This latest addition to the Additives for Recycling portfolio of solutions is a polyolefin compatibilizer developed to enhance and support the use of recycled polyolefins. It helps bring incompatible polymers, such as PP and PE, together by forming them into a homogenous polymer mixture that increases mechanical properties based on polymer modification (link to full press release above). Unique technologies  that  improve  the  recyclability  of  products  and  enable  recycled content to be incorporated, thus advancing a more circular economy
