Recycled Content & Recyclability We offer color concentrates that use post-consumer recycled (PCR) polypropylene (PP) and polystyrene (PS) as carrier resin. Recyclability Assessment at CycleWorks™ Our Cycleworks™ Innovation Center specializes in testing and evaluating recycling solutions. Recycling trials taking into consideration standard recycling protocols can be run to provide a real- world recyclability evaluation.

Startup & Shutdown Recommendations Purge Compound HDPE or HIPS Recycling Recycling Gravi-Tech up to 25% is permissible. Testing the application is highly recommended to determine the effect recycling has on the desired physical properties. Recycling above 25% will have to submit to validation testing, before it can be accepted.

STARTUP & SHUTDOWN RECOMMENDATIONS Purge Compound HDPE or HIPS Recycling Recycling Edgetek™ 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: - PPA Compounds: 0.0015"–0.0025" depth and 0.250" width - PC Compounds: 0.002"–0.004" depth and 0.250" width - PSU Compounds: 0.003"–0.004" depth and 0.250" width - PES Compounds: 0.003"–0.004" depth and 0.250" width - PPS Compounds: 0.002"–0.003" depth and 0.250" width - Acetal Compounds: 0.0015" minimum depth and 0.250" width - PEEK Compounds: 0.002"–0.004" depth and 0.250" width - Nylon Compounds: 0.002" minimum depth and 0.250" width • Increase vent depth to 0.060" (1.5mm) at 0.250" (4.0mm) away from the cavity and vent to atmosphere.
