ER3, a breakthrough in innovation and technology, was the first product of its kind. 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 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 ReStart® flooring reclaimation and recycling program and are certified at the Platinum level to the ANSI/NSF 140 standard. The ER3 product line consists of styles made with a wear layer composed of either nylon 6 or nylon 6,6 which is solution dyed, yarn dyed or a combination of solution and yarn dyed. This product group was 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.
