With a single pioneering green chemistry, Milliken & Company addressed one of the top five environmental health risks related to floor and wall coverings—indoor air quality (IAQ). To improve IAQ, research focused on eliminating on-site applied adhesives. The resulting adhesive-free installation system addresses the mechanisms to reduce effects of the three major classes of IAQ pollutants on building occupants in unique ways for each product. Bio-based TractionBack^TM applies to the overall chemistry for the application and the patented high-friction coating used to keep carpet securely in place without the use of wet adhesives, floor sealers or primers during repeated installations. Modular carpet with TractionBack will not move laterally on the floor, but lifts vertically to access underfloor wiring, replace damaged tiles or change carpet to reconfigure the space. The ground-breaking technology offers multiple cost, time and environmental advantages. Through life cycle assessments, Milliken replaced selected petroleum-based components of the initial formulation with bio-based surrogates to further reduce its environmental impact. The second equally revolutionary product is a patent pending pressure sensitive wall covering, 180 Walls^TM, which hangs without paste using a proprietary water-based acrylic, experiences no wet movement, shrinkage or corner peel and can be removed years later without wall damage. Milliken introduced PVC-free carpet tile backings in 1986. Today 180 Walls^TM provides an alternative to PVC-based vinyl wall coverings. Milliken remains dedicated to developing products and practices that rely on green chemistry to out-perform traditional non-sustainable solutions.
