COLORMATRIX™ OXYGEN SCAVENGER PRODUCT FAMILY Amosorb™ and Amosorb™ SolO2 active oxygen scavengers ColorMatrix™ Amosorb™ additives are oxygen scavenging polyester concentrates that create an active barrier against the ingress of oxygen through the walls of PET containers. These ready-to-use technologies offer extended shelf life capabilities and the flexibility to manage the additional demands of rPET usage, resin compatibility and flexibility, sustainability, light- weighting, aesthetics, market seasonality and carbonated oxygen sensitive beverages.

ColorMatrix™ rePrize™ is a patent- protected, liquid formulation IV builder designed for addition to the extrusion process during the manufacture of rPET. ColorMatrix rePrize is a very reactive additive and any changes to the extruder temperatures and parameters will have an effect on melt viscosity of the polymer and also the finished article.

Higher levels of acetaldehyde; off-taste in water ColorMatrix™ Triple A™ Acetaldehyde Scavenger Additive to control levels of acetaldehyde within the preform, allowing for higher levels of rPET to be used. Color degradation; product protection ColorMatrix™ Ultimate™ UV Light Barrier APR/EPBP approved additive to block ultraviolet light transmission Protects the product and brand integrity during storage, transportation and in the retail environment, maintaining product quality and enhancing shelf life.

Consider, too, that additional supply chain issues regarding pigments, stabilizers and additives that are regularly rationalized out of production can leave you scrambling for last minute formulation alternatives that require requalification.

In addition, this material can be used in tools originally constructed for halogenated materials with no rework required. Additional advantages of these TPEs include: • Highly flame retardant without the inclusion of halogens • Low temperature flexibility • Excellent processability • Good abrasion resistance • Excellent colorability • Operating temperatures from -50° C to +100° C • All grades meet UL94-V0 at 1.5 mm • All grades pass IEC 60695-2-12 Glow Wire Flammability Index (GWFI) at 960°C

Antimony trioxide has the unique ability to make halogen-based plastic additives more effective in reducing the flammability of the finished plastics. ATO has also been found to be useful as a catalyst for PET manufacture, as a frictional additive in automotive brake linings, as a clarifier for glass, as an opacifier for enamels, as a coating for titanium dioxide applications, and as a stabilizer for certain pigments.

Flame-retardant technology uniquely embedded into the panel materials provides robust and durable fire performance without the need for additional sheets or coatings. KEY BENEFITS • Lightweight: Significantly lighter than traditional materials such as wood, drywall, and framed wall assemblies, offering a lightweight yet durable solution for easier transport and installation, while maintaining structural integrity • Durability: Resistant to rot, moisture, chemicals, UV, and corrosion, ensuring long- lasting performance • Efficiency: Consolidated structural panel reduces labor and assembly time, maintaining structural integrity throughout the installation process • Versatility: Can replace gypsum and drywall in wall construction, offering strong adhesive bonding properties and paintable surfaces • Material Consolidation: Integrates flame retardant properties and eliminates the need for additional sheets or coatings for fireproofing, simplifying the building process • Highly Customizable: Avient offers a wide range of custom size configurations and panel options, allowing builders to meet specific project needs • Sustainability: FR technology is not halogenated or phosphorus-based, and is made with benign ingredients at low concentrations, making it an environmentally friendly option Hammerhead™ FR Flame Retardant Composite Panels PRODUCT OVERVIEW APPLICATIONS • Modular Construction Structures: Ideal for rapid assembly, reducing construction time and costs • Walls: A durable and lightweight alternative to traditional wall materials, suitable for both interior and exterior applications • Flooring: Provides a strong and stable base for various flooring systems, withstanding heavy loads and traffic • Garage and Industrial Doors: Offers excellent strength-to-weight ratio and resistance to impact and weather, making it an excellent choice for demanding environments 1.844.4AVIENT www.avient.com Copyright © 2025, Avient Corporation.
