PRODUCTS APPLICATIONS DESCRIPTION/BENEFITS EXCELITE PF-1 PVC sheet for digital print or trimboard; profiles & decking 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; profiles & decking 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; profiles & decking 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. This process allows greater control over production tolerances, thus reducing scrap rates, improving quality, and optimizing process capacity.
