POLYOLEFINS ALIGNING WITH SUSTAINABILITY GOALS POLYOLEFINS ARE EVERYWHERE Polyethylene (PE) and polypropylene (PP) are among the most popular plastics in the world.

FDA/EU compliance information available upon request REMAFIN™ EP White Colorants for Pharmaceutical Packaging REMAFIN™ EP is a range of PE and PP based masterbatches designed for protecting oral, topical, parenteral, ophthalmic and nasal pharmaceuticals by opacifying primary and secondarypharmaceutical packaging.

Extrusion-specific concentrates are available for most common packaging resins, including PP, PE, PS, PET, and PLA.

BENEFITS OF THE CHEMICAL FOAMING PROCESS • Standard equipment compatibility: Maxxam formulations can be processed using standard extrusion equipment, eliminating the need for specialized machinery • Chemical foaming formulation: No investment in gas injection systems or procurement of gas is required • High foaming rates: Achieve up to a 60% foaming rate, optimizing material properties while maintaining performance • Adapted temperature profile: These foamable grades are formulated to work effectively within a tailored temperature profile, offering consistent quality MAXXAM PP COPOLYMERS ARE SPECIALLY FORMULATED TO DELIVER • High-temperature performance: Suitable for applications requiring resistance to elevated temperatures • High foaming rate for cellular formulations: Contributes to better electrical properties due to low density • Excellent mechanical properties: Provides durability and reliability in demanding environments KEY CHARACTERISTICS OF CELLULAR PP FORMULATIONS • Fully formulated PP: no need for other additives • Can be based on chemical foaming agents which are not hazardous substances for a sustainable production process • No need for gas injection • Excellent surface finish and uniform cell structure • Excellent electrical properties to reach stringent capacitance • Low shrinkage • Adapted for skin-foam-skin or foam-skin design • Higher temperature resistance compared to PE • Good crush resistance MARKETS & APPLICATIONS IN WIRE & CABLE • Communication cables such as telecom and data cables • Twisted wire pairs • Coaxial cables

D’une part, l’entreprise Avient Corporation s’est engagée à : - utiliser le protocole de tri fournis par le COTREP (« Procédure de tests de tri optique COTREP pour évaluer la détectabilité d’emballages sombres lors des étapes de tri optique » - version Janvier 20191) ; - réaliser les tests chez les deux Fabricants T.O. représentatifs des capacités de tri existantes en France ; - remettre au COTREP les rapports des essais pour analyse et avis ; - proposer une solution colorante : o qui réponde aux exigences essentielles de la directive emballage 94/62/CE o qui ne fait pas basculer la densité de l’emballage : les emballages majoritairement en PP ou PE doivent conserver une densité < 1 et les emballages majoritairement en PET ou en PS une densité > 1.
