Sustainable and Density Modified  These polymer formulations have been developed to achieve equivalent performance to prime density modified solutions with added sustainability benefits, such as reducing waste and supporting the circular economy, and reducing product carbon footprint.     Sustainable Engineered Polymers

A COMPLETE PRODUCT PORTFOLIO A full range of Colorant Chromatics technologies includes: • Color and/or additive concentrates • Specialty compounds including conductive, carbon fiber, CNT, filled, glass, carbon, minerals • Additive concentrates including specialty compounds such as UV, acid scavengers, lubricants/mold release, and foaming agents • � Pigment dispersions • �� Inks and additives for processors of high- performance plastics and fluoropolymers HIGH- TEMPERATURE SOLUTIONS/ INJECTION MOLDING Minimum order quantities for color concentrates and compounds for high-performance polymers are as low as 10 lbs. (5kg), enabling you to manage inventory better and order only what you need. Controlled dispersion and high-quality carbon black materials enable you to achieve optimal performance for high-temperature extrusion and molding processes. Carbon/Graphite Fiber compounds can help you increase the mechanical strength of your injection molded parts with increased flex modulus.

Renol™ Fiber Colorants Deep Black Colorants for PET Fibers The textile market, particularly in the automotive textiles, apparel, and home decor sectors, has long sought after deep black colorants that offer exceptional jetness and light fastness without incurring exorbitant costs. The Renol™ Fiber Colorants portfolio includes deep black solutions with high light and washing fastnesses for polyester fibers including recycled grades. This one-in-one process involves no water, making it a more sustainable dyeing process.

UL94 COMPLIANT MASTERBATCHES DESIGN & SAFETY High-impact colors and cutting-edge design are hugely important to the success of today’s sleek, modern electrical and electronic products. Avient offers masterbatch solutions to fulfill different levels of Glow Wire temperatures. In order to have a masterbatch recognized by UL, the following conditions must be met: • the color concentrate producer must be recognized by UL • the polymer, generic or specific, must be recognized as well • the recognition of the material combination (base resin + color concentrate) must be listed in the QMSQ2 file of the concentrate producer • the specification limits set in the QMQS2 file must be respected if the UL94 recognition is to apply to the final plastic part Avient has a wide range of color and cost options available to provide maximum flexibility.
