Screens and evaluates additive and colorant systems in the recycling process ColorMatrix™ Optica™ Toners & Colors for Enhanced Recyclability

Color and Additives Solutions Overview Colorant and additives overview and capabilities

This includes technologies for lightweighting, colorants for secondary paint replacement, and bio-polymers. Experts from Avient will be on hand at booth #24 throughout the conference to help customers better understand novel sustainable performance materials, including specialized polymer colorants, functional additives, and engineered material formulations. 

Ranging from colorants and additives to engineered polymer formulations, these solutions can help customers operate more efficiently and design better. PolyOne is also announcing the availability of the reSound™ NF Natural Fiber Reinforced Composites in brilliant colors and extrusion formulations, making the material more useful for building & construction, sporting goods and other applications.

The beam changes the molecular structure of the additive, causing a color change that results in a permanent marking. Sourcing the additive as a masterbatch, often bundled with colorant, makes it easier to add to your production process.

Mevopur™ Healthcare Colorants and Formulations Special Effect Colorants for Healthcare Devices and Pharmaceutical Packaging Self-administered medication, for example via pen devices and inhalers, has been the norm for many years. Ingredients used in the Mevopur™ portfolio have been tested to industry standards that support applications in both medical devices and pharmaceutical packaging.* KEY CHARACTERISTICS • Manufactured at four ISO 13485 certified manufacturing sites, providing global consistency and increased security of supply • Documented change control beyond CAS number, reducing risk of change • Non-phthalate and formulated without animal-derived substances • Available as pre-colored formulation or concentrate and for use in 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 * Design note: Effect colors require careful consideration of part design and polymer flow paths to minimize visible flow lines.
