Low density I-skin urethane (PU) foam system (natural color) HFC 245fa-blown, two-component microcellular polyurethane foam system designed for molding of miscellaneous Integral Skin articles that require good skin at relatively low molded densities. Depending on the application requirements and the processing conditions this system can provide - Exceptional skin formation when casted in metal tools at low mold temperatures - Wide range of molded densities from 10 to 25 pcf - Hardness range from 10 to 70 Shore A - Wide processing window on both low-pressure and high-pressure equipment
