Overmolding Nylon/Polyamides (PA) Overmolding to a wide variety of modified and filled nylons is now possible with solutions from Avient. Versaflex™ OM 6059-9 – High flow nylon overmold   

These properties offer manufacturers a high-performing, cost-competitive, and more eco-conscious alternative to nylons. These materials also offer a sustainability benefit through a reduced carbon footprint because PK base resin production emits up to 61 percent less carbon dioxide (CO2) than nylon, helping to improve sustainability over the end-product lifecycle. When processing, these have similar shrink to nylons, set up quickly, and have short cycle times.

Versaflex™ TF Adhesive TPE solutions, developed for adhesive films in laminations with nylon and polyester textile fabrics, enable brand owners and OEMs to create a new generation of soft, stretchable, and breathable fabrics for athletic apparel such as sportswear and underwear. Compared to TPU adhesive films and traditional glue, these new TPE solutions can deliver a seamless and strong adhesion to polyester and nylon fabrics, enabiling a uniform thickness and overall appearance for an athletic, close-fitting, and non-bruising finish. KEY CHARACTERISTICS • High-wearing comfort and elastic recovery • Strong and seamless adhesion to polyester and nylon fabrics • Passed OEKO-TEX 100-2 testing • Excellent washability at up to 60°C • Non-toxic formulations with low volatile organic compounds (VOC) and without added plasticizers • Attractive alternative to conventional TPU adhesive film and glue MARKETS & APPLICATIONS Versaflex TF Adhesive TPE solutions have been custom engineered for: • Elastic strips in underwear • Seam tapes in sports and fitness apparel PRODUCT BULLETIN 1.844.4AVIENT www.avient.com Copyright © 2024, Avient Corporation.
