发明名称 Cellular thermosetting fluoropolymers and process for making them
摘要 Thermosetting fluorodiepoxide polymer foams are made by mixing fluid form thermosetting fluorodiepoxide polymer components having a substantial fluorine content, placing the mixture in a pressure tight chamber, filling the chamber with a gas, at relatively low pressure, that is unreactive with the fluorodiepoxide polymer components, allowing the mixture to gel, removing the gelled fluorodiepoxide polymer from the chamber and thereafter heating the fluorodiepoxide polymer at a relatively low temperature to simultaneously cure and foam the fluorodiepoxide polymer. The resulting fluorodiepoxide polymer product is closed celled with the cells storing the gas employed for foaming.
