MODIFIED POLYURETHANE PRODUCT HAVING IMPROVED LOAD-BEARING CHARACTERISTICS Inventor: Morey Weisman, a citizen of the United States of America and resident of Jamaica, New York ABSTRACT OF THE DISCLOSURE A modified low-density flexible polyurethane foam product having a relatively high degree of firmness as well as commercially acceptable dielectric heat sealing characteristics. The product formulation includes an intermediate constituted by a mixture of polyol and a polymer/polyol in a ratio im- parting to the product a predetermined degree of firmness, and a thermoplastic additive whose dielectric loss index is greater than the loss index of polyurethane foam to impart to the product an acceptable dielectric heating response in a high frequency electric field. This response is enhanced by a styrene component included in the polymer/polyol. -1-
