MAGIQ™ FIBER COLORANT & ADDITIVE TECHNOLOGY INTRODUCING MAGIQ FIBER COLORANT AND ADDITIVE TECHNOLOGY FOR THE MASS DYEING AND FUNCTIONAL MODIFICATION OF SYNTHETIC FIBERS, OF WHICH AVIENT IS A LEADING MANUFACTURER. Our specialty fiber solutions are commercialized under our MagiQ™ brand of fiber colorants and additives, which incorporate Magenta Master Fibers, IQAP, OnColor™, OnCap™ and ColorMatrix™ Fiber Colorant Solutions. With a FlexCart system, it is possible to achieve continuous, consistent and accurate dosing—even at very low addition rates.

This includes the launch of OnFlex™ LO thermoplastic elastomers (TPEs), featuring reduced levels of volatile organic compounds (VOCs) for vehicle interiors, and the availability of its IQ Design Labs service in Europe. PolyOne continues to introduce new polymer solutions and design services to help our customers innovate,” explained Holger Kronimus, vice president and general manager, Specialty Engineered Materials, Europe, at PolyOne.

These new grades are developed to enhance the performance of thermoplastic polyurethane (TPU) film-laminated products and devices in applications where combating microbe development is highly important.   Dyneema®, the world’s strongest fiber™, enables unmatched levels of performance and protection for end-use applications, including ballistic personal protection, marine and sustainable infrastructure and outdoor sports Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation and fiber optic / 5G network accessibility  

A bluish undertone is often desirable for thermoplastic articles, particularly for polymers with a slightly yellow cast. Topical optical brighteners have been used to improve the surface whiteness of plastic articles and synthetic fibers.

Examples include: • Barrier technologies that preserve the shelf-life and quality of food, beverages, medicine and other perishable goods through high- performance materials that require less plastic • Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation • Breakthrough technologies that minimize wastewater, improve the recyclability of materials and advance a circular economy • Composite solutions to support accelerated growth of 5G / fiber-optic infrastructure investment as the world demands greater and faster connectivity Avient employs approximately 8,400 associates and is certified ACC Responsible Care® and a founding member of the Alliance to End Plastic Waste. Operational Excellence Empowers us to respond to the voice of the customer with relentless continuous improvement. We will do so though our investments and focus on sustainable solutions for high-growth markets, including healthcare, consumer, packaging and composites/5G.
