GE Advanced Materials introduced a new family of silicone surfactants for hydrocarbon (HC) blown foam insulation used in the appliance industry. According to the company, the NIAX® Silicone L-6884 and NIAX Silicone L-6988 silicone surfactants represent a breakthrough in the manufacture of rigid polyurethane foam systems based on HC agents. The new products are said to improve the solubility of HC into the polyurethane system for a stable mix and enable formation of very fine foam cells with superior insulating properties.
