A fire-resistant polyurethane foam is provided. A hydroxyl-containing inorganic fire retardant is premixed with a polyisocyanate and a polyol, respectively, to form two premixtures. Then, the two premixtures are mixed for reaction to form a fire-resistant polyurethane foam. Preferably, a combination of different particle sizes of the fire retardant is employed to maximize the amount of the fire retardant and increase the fire resistance of the foam.

Fire-resistant polyurethane foam and fabrication method thereof

The invention relates to a process for preparing gas separation membranes or modules. Membrane forming material is cast into a wet membrane which is wound into a spiral module. The spiral module is arranged in a closed circulating apparatus. Exchanging solvents or treating solutions are circulated through the circulating apparatus and the spiral module for an appropriate period of time. The module and circulating apparatus are purged until the membrane is dry, thus producing a gas separation membrane or module.
