Accountability and responsibility are the foundation for Tarkett’s product development and design innovations. Tarkett’s ER3, a breakthrough in innovation and technology, was the first product of its kind in the industry. The ER3® modular product line consists of a full range of styles made with a nylon wear layer and ER3 recycled content secondary backing made from pre and postconsumer carpet. The product wear layer is composed of nylon 6 or nylon 6,6 which is solution dyed, yarn dyed or a combination of solution and yarn dyed. The nylon wear layer and secondary backing are fused together through heat and pressure to form an integral and inseparable construction that provides excellent performance and durability. ER3 modular products are fully recycable in Tarkett’s third party certified, closed loop carpet recycling process and are certified at the Platinum level to the NSF/ANSI 140 standard. This product group was assessed for an average face weight of 20 ounces per square yard (osy), with the maximum (32 osy) and minimum (12 osy) yarn weights assessed for sensitivity. Unless otherwise noted, data is presented for an average product with 20 osy yarn weight.
