METAL REPLACEMENT COMBINES METAL’S STRENGTH WITH PLASTIC’S LIGHT WEIGHT CASE STUDY: COMPLĒT™ LONG GLASS FIBER REINFORCED COMPOSITE Ch all en ge A cc ep te d. Avient’s team also provided hands-on design recommendations to minimize knit line concerns and address structural requirements. Using the new Complēt long glass fiber nylon formulation, the redesigned yoke underwent testing at Bettcher to simulate 500,000 run cycles.

These materials are based on select engineering thermoplastic resins that are formulated with reinforcing additives such as carbon fiber, glass fiber and glass beads.

Avient Introduces CESA™ Fiber Additives for Heat Preservation to Help Meet Fashion Design’s Functional Needs. SHANGHAI – 2022年4月13日 – Avient today launched CESA™ fiber additives, a new generation of heat-preservation additive formulations for fiber and textile applications to help brands more easily meet consumer demand for lightweight, comfortable outdoor clothing.   Fabrics made with CESA fiber additives can absorb more heat when exposed to solar rays.

Homepage // News Center // Avient Launches Long Fiber Composites Based on Nylon Reclaimed from End-of-Life Fishing Nets We’re delighted to be introducing our first recycled-content long fiber composite material in a planned larger portfolio based on recycled resin,” said Eric Wollan, General Manager for Long Fiber Technologies at Avient. Formulations are available globally in a standard black color at typical weight percentages of long glass fiber, long carbon fiber, or hybrid combinations.

Drawing on the wealth of Avient expertise, our shooting sports customers find fresh ways to add value to existing product lines as well as bring innovative new designs to life. From product design to manufacturing and supply chain efficiencies, we help you bring next generation products to market faster, gain customer loyalty, and boost your bottom line.

FASTER TO THE FINISH LINE WITH COMPOSITES IN RUNNING SHOES FIBERGLASS REINFORCED COMPOSITES ENHANCE INSOLE PERFORMANCE AND COMFORT THE CHALLENGE Running is a passion for many people around the world. According to Gordon, carbon fiber, despite its energy-returning effects, is not as friendly as fiberglass for a runner’s muscles, tendons, and joints. They fit comfortably in most athletic shoes, including racing spikes, with the glass fiber properties providing comfort and performance benefits to the user.

Using these process aids can result in greater production efficiencies with faster extrusion line speeds and molding cycle times. Improves line speeds and cycle times, leading to reduced energy use during processing Improved line speed and enhanced aesthetics with PVDF processing aid

The line of additives includes the new Mevopur chemical foaming agents that help manufacturers of pharmaceutical packaging and medical devices add another level of sustainability to their products. Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation and fiber optic / 5G network accessibility
