Disclosed is a product and process for a substantially halogen-free thermoplastic elastomer. The thermoplastic elastomer can be incorporated into a decorative surface covering as a binder with the addition of an optional filler. The substantially halogen-free thermoplastic comprises the combination of a dynamically vulcanized blend of epoxidized natural rubber (ENR), ionomers and a diluent polymer such as ethylene vinyl acetate (EVA). The combination produces a pliable and flexible flooring product.
