KEY CHARACTERISTICS • Manufactured at four ISO 13485 certified sites, providing global consistency and increased security of supply • Documented change control beyond CAS number, reducing risk of change • Available as additive concentrates, ready-to-use additive formulations or ready-to-use additive/ colorant formulations for different polymers REGULATORY SUPPORT • Raw materials tested to: - ISO 10993-1 and USP biological evaluation - European Pharmacopeia 3.1.3/3.1.5 (polyolefin) - USP (polyethylene) - ICH Q3D elemental impurities • Registered Drug Master File (Type III) and/or Device Master File • Food contact established with FDA/EU* APPLICATION BULLETIN * FDA/EU compliance information available upon request; exceptions may occur Healthcare use limitations apply—see below. It is the responsibility of the medical device manufacturer and the person placing the medical device on the market to ensure compliance of the medical device with all applicable laws and regulations, including the suitability of all raw materials and components used for its manufacture.

These materials provide consistent conductivity at any location on the pipette tip, as well as from manufacturing run to manufacturing run. Working together, we can help you arrive at an optimal solution with speed and accuracy, while helping to lower product development and manufacturing costs.

With faster material lead times, manufacturers of 5th generation (5G) antennas can qualify designs faster and meet the demands of rapidly deploying 5G infrastructures. Small Part Manufacturing Capabilities – Thermoplastics can be molded into smaller parts, whereas the manufacturing process of traditionally used materials limits this capability.

Avient™ ColorMatrix™ Joule Reheat Additive Proprietary IR Absorber Avient™ ColorMatrix™ Joule reheat additive is a proprietary IR absorber manufactured and marketed by ColorMatrix worldwide for use in PET resin formulations suitable for carbonated soft drinks and beverage applications. Occasionally, technicians from the equipment manufacturers are used to establish the ‘entitlement’ performance of a particular machine and most major manufacturers have technical service teams to help with this activity.

Formulations are heavy metal-free and manufactured using state-of-the- art pigment dispersion techniques that improve homogenization and color distribution. KEY CHARACTERISTICS • Consistent coloring and improved homogenization with the polymer for more efficient processing and waste reduction • Opaque PSU/PES/PPSU masterbatches available with shorter lead times in a range of readily available standard colors • Minimum order quantities as low as 5kg (10lbs) for improved inventory control • Robust colorant formulations mean zero disruption to existing molding processes, allowing manufacturers to bring products to market faster and without investing in new machinery PRODUCT BULLETIN 1.844.4AVIENT www.avient.com Product Code Color LDR* Pantone No.** 650.00 Black 10% 433C 650.01 Brown 10% 7615C 650.02 Red 10% 186C 650.03 Orange 5% 1495C 650.04 Yellow 10% 142C 650.05 Green 10% 2248C 650.06 Blue 10% 278C 650.07 Violet 20% 2073C 650.08 Grey 10% Cool Gray 7C 650.09 White 10% RAL9010 PPSU RESINS Product Code Color LDR* Pantone No.** 660.00 Black 6% Black 6C 660.01 Brown 6% 7582C 660.02 Red 8% 7620C 660.03 Orange 6% 1505C 660.04 Yellow 6% 124C 660.05 Green 6% 348C 660.06 Blue 6% 660C 660.07 Violet 15% 7664C 660.08 Grey 6% Cool Gray 8C 660.09 White 6% RAL9010 PSU RESINS Product Code Color RAL No.* S837.0 Black 9005 S837.1 Brown 8011 S837.2 Red 3002 S837.3 Orange 2004 S837.4 Light Yellow 1016 S837.5 Green 6032 S837.6 Blue 5015 S837.7 Violet 4005 S837.8 Grey 7037 S837.9 White 9016 PES RESINS Copyright © 2021, Avient Corporation.
