Abstract

Multiple layer laminates contain predominantly urethane-based polymeric materials in cap and base layers, and no significant amount of PVC. Under combustion conditions, the laminate releases substantially no harmful halogen-based bases, such as HCl or other toxic gases, and exhibits low toxicity and smoke generation.
