EXCELITE VS POWDER • Enables a greater level of density control, through consistent distribution in the polymer • Simplifies and optimizes resin compounding capabilities (PVC dry blends) • Enables greater control over foaming and expands processing window when re-introducing regrind • Clean and highly accurate dosing process, with fewer of the health and safety concerns that can become apparent with powder CFAs EXCELITE VS PELLET • Being significantly more concentrated, Excelite additive enables lower total cost to foam • Can achieve lower density, less carrier influence • Finer and tighter cell structure through better additive distribution • Improved linear consistency of cell structure as ColorMatrix pumps continually meter output, giving greater stability over material dosing • Improved plant working capital as lower let down ratios means less material is consumed and reduces inventory holdings TECHNICAL SUPPORT • Avient has a market leading service team which understands foaming processes, we assist customers to deliver performance and production efficiencies with Excelite™ technology • Please contact your local Avient representative for additional information on our line of foaming additives www.avient.com Copyright © 2020, Avient Corporation.
