Product/Service Overview Product/Service Overview Product/Service Overview

• Cesa™ Unify™ A4R Polyolefin Compatibilizer helps bring incompatible polymers like PP and PE together by forming them into a homogenous polymer mixture which increases the mechanical properties of the recycled polymer. • Cesa™ impact modifier for polystyrene improves the impact strength of recycled polystyrene (rPS) with limited impact on the Young’s modulus. COLOR SOLUTIONS • OnColor™ Polymer Colorants customized to customer’s requirements are color matched taking into consideration the recycled resin grade specificities and application requirements. • Our PCR Color Prediction Service helps frame the available color space based on the PCR characteristics including opacity and undertone for recycled polyolefins, PET, and styrenics. • SmartBatch™ Combination Colorants & Additives based on Maxxam™ REC Recycled Polyolefin Formulations which include 25–100% recycled polyolefin resin from post-industrial recycled (PIR) and/or post-consumer recycled (PCR) sources.
