If the material is shear-sensitive, consult the material data sheet or processing guide for instructions to set recovery time • The cooling time should only be 1–2 seconds longer than the screw recovery time, unless dictated by dimensional stability or part thickness Minimize Clamp Pressure This step is done to reduce the amount of energy used by the machine Shot Size = 1.00 + .10 = 1.10, Transfer Position = .50 + .10 = .60 Set Safeties This step is to ensure the machine will alarm and alert nearby employees if the machine malfunctions, or if a part gets stuck Very difficult to resolve through processing Root cause: Nominal wall thickness is not maintained or uneven cooling. 42 Gravi-Tech Uneven cooling Damaged ejection Leaking check ring New lot Melt temperature Injection speed too high Cooling time too low Hold pressure too high Hold time too low Transfer too high Plate with lower friction coating Maintain constant wall thickness Maintain constant cooling Reduce sharp corners Gate from thick to thin Increase/decrease cooling time Reduce mold Reduce melt Warpage • Parts will warp to the hotter half of the mold Root cause: Internal stresses caused by uneven shrinkage.

The technology is highly suitable for printable sheet, where smooth surface finish and low density is a requirement. PRODUCTS APPLICATIONS DESCRIPTION/BENEFITS EXCELITE PF-1 PVC sheet for digital print or trimboard; Fine cell structure able to target low density: improves consistency and control over foaming process FOAM ADDITIVE-54 PVC sheet for digital print or trimboard; Finer cell structure than PF-1 promotes ultra smooth surface finish; improves consistency and control over foaming process PF-1E & FA-54E ADDITIVES PVC sheet for digital print or trimboard; Enhanced run time formulation reduces die lip build-up in PVC processes, leading to longer production run times FOAM ADDITIVE-33 CaZN formulations for PVC sheet, profile, or trimboard Promotes finer cell structure, higher cell density, and surface quality in CaZN PVC dryblends FOAM ADDITIVE-77 HDPE sheet & plastic lumber Industry-leading cell structure and cell density; achieves lower density without sacrificing quality; self-nucleating and able to increase extruder output rates up to 15% FOAM ADDITIVE-85 Endothermic foam or nucleating additive for olefin and styrene polymers; plastic lumber, sheet applications and food packaging products Can be used as a CFA or nucleating additive; nucleating capabilities promote fine cell structure and high cell density; achieves greater density reductions with more consistency and control FOAM ADDITIVE-37 HDPE sheet & plastic lumber Good cell structure and cell density in HDPE lumber; greater consistency and control over foaming process EXCELITE CAN IMPROVE PRODUCTION EFFICIENCY • The process operator has full control of density • Minimizes product rejection due to unnecessarily high/low density • Production should consistently target the bottom of the density specification • Enables control over the reintroduction of regrind or reprocessed materials as a feedstock • Enables the consistent foaming of products using higher percentages of regrind • Carrier selection can promote longer run times, enabling increased line productivity through less plate-out or material build-up on die lips EXCELITE CAN IMPROVE SURFACE FINISH Excelite additives creates a fine, consistent cell structure within the extruded polymer, which determine the surface roughness. 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.

They also eliminate the need for secondary coating or wetting processes to achieve equivalent performance while reducing production costs. Based in polysulfone resins, they provide ultra-high-heat resistance and performance without compromising safety while also responding to the needs of extended shelf life. This cutting-edge tool offers an important data point for the carbon footprint of Avient’s materials so customers can better understand the environmental impact of products, meet sustainability goals, and navigate the complex landscape of reducing carbon emissions.

These grades offer the same performance as the standard series but with improved adhesion for metallization, coating or 2K injection molding. Films, sheet, filaments They are typically used in films, sheet, filaments or applications that need extensive bending.

These materials combine the performance of select engineering resins with reinforcing additives, such as carbon powder, carbon fiber, nickel-coated carbon fiber and stainless steel fiber, for low-to-high levels of conductivity depending upon application requirements.
