The Flex-Aire® Cushion modular product line consists of a full range of styles that combine a nylon wear layer and closed cell cushion in a heterogeneous construction. The nylon and closed cell cushion are fused together through heat and pressure to form an integral and inseparable construction that provides excellent performance, durability and comfort underfoot. The closed cell nature of the cushion layer provides softness underfoot as well as structural support. The enhanced cushion layer increases the acoustical and insulation properties of the product and gives longer wear life to the face yarns. Innovative patterns and and extensive offering of color palettes, allows Flex-Aire Cushion modular products to work in tandem with other Tarkett products. Flex-Aire Cushion is an ergonomic modular product that is fully recyclable in Tarkett’s third party certified, closed loop carpet recycling process. It is also certified at the Gold level to the ANSI/ NSF 140 standard. The product is composed of either nylon 6 or nylon 6,6 which is solution dyed, yarn dyed or a combination of solution and yarn dyed. These product groups were assessed for an average face weight of 18.1 ounces per square yard (osy), with the maximum (30 osy) and minimum (10 osy) yarn weights assessed for sensitivity. Unless otherwise noted, data is presented for an average product with 18.1 osy yarn weight.
