    Abstract: A method of making thermal insulating products comprising porous, lightweight, high temperature resistant inorganic particles in a polyimide foam matrix and the product thereof. A polyimide precursor powdered is mixed with about equal weight of flake-like porous inorganic particles to substantially uniformly coat the particles with powder. The mixture is placed in a mold and compressed slightly. The assembly is heated to the foaming temperature of the polyimide precursor for a period suitable to produce uniform foaming. Then the temperature is raised to the curing and crosslinking temperature of the precursor for a time period sufficient to produce complete cure. A high temperature and flame resistant, light weight, highly insulating product results. If desired, protective sheets of material may be bonded to selected product surfaces during or after the molding operation.

    Abstract: Pre-expanded styrene polymer particles, which may contain one or more pre-expanded styrene polymer beads, are coated with sufficient water glass so that the particles, when dried to a reversible, tack-free pourable state, comprise from about 30% to 80% styrene polymer solids. The particles may be shaped into a desired article configuration and then dried to a tack-free state, the particles adhering together through the water glass, and the resulting article having a bulk density of from about 1.25 lbs. to 3 lbs. per cubic foot. The water glass or the pourable particles may be treated to decrease alkalinity and to cause irreversible precipitation of water glass solids, rendering the final product essentially waterproof.

    Abstract: A fireproof material incorporating aerogel with an organic foam material and a method for making the same are provided. The method is carried out as follows: A. a mixed solution of a precursor and an organic solvent is added with an acid catalyst and becomes an anhydrous aerogel solution through hydrolysis; B. the anhydrous aerogel solution is added with an aqueous alkali catalyst solution and forms an aerogel solution through condensation; C. an organic foam material is impregnated with the aerogel solution such that aerogel is generated by gelation and is incorporated with the organic foam material, forming a three-dimensional reticular structure; and D. the organic foam material incorporated with the aerogel is dried and then shaped to produce a fireproof material. The fireproof material is highly proof against fire and can pass the limiting oxygen index test.
