  • POLYURETHANE BASED RIGID FLOORING LAMINATE
    Publication number: 20190315092
    Abstract: The laminate according to the invention is a multiple layer structure and contains predominantly urethane-based polymeric materials in the cap and base layers thereof, with no significant amount of PVC. As such, under combustion conditions, the laminate releases substantially no harmful halogen-based bases, such as HCl or other toxic gases, and exhibits toxicity and smoke generation parameters well below acceptable industry standards.
