STARTUP & SHUTDOWN RECOMMENDATIONS Purge Compound HDPE or HIPS Recycling Recycling LubriOne up to 20% is permissible. 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.

Avient’s transportation portfolio includes sustainable technologies that offer lightweight structural alternatives to metals, while delivering comparable or improved performance; reduce volatile organic compound (VOC) emissions to improve interior air quality; specialty colors & effects enable paint replacement technologies.

A compounding extruder connected to the impregnation die functions as a melt pump feeding molten thermoplastic polymer into the process.
