Abstract:
A method of using metallized and nonmetallized nanostructured chemicals as surface and volume modification agents within polymers and on the surfaces of nano and macroscopic particulates and fillers. Because of their 0.5 nm-3.0 nm size, nanostructured chemicals can be utilized to greatly increase surface area, improve compatibility, and promote lubricity between surfaces at a length scale not previously attainable.
Abstract:
Opened-celled porous plastics or natural products are made flame retardant by coating the cell walls with a liquid containing carbonization auxiliaries and/or flame retardant agents. The excess liquid is removed and the mass is dried. The open-celled porous mass now has good fire characteristics. The carbonization auxiliaries and/or flame retardant agents may also be used in the production of the open-celled porous organic masses. These flame retardant porous masses may be used in furniture, mattresses, fire barriers, textile coating, laminates, linings and as insulators.
Abstract:
The insulation barrier is formed of a body of foamed polystyrene, either expanded or extruded, which is provided with a protective coating formed of a metallic-based inorganic material and is applied over at least one surface of the body. Optionally, a fire resistant composition of any inorganic silicate, boric acid, any salts of boric acid, hydrated sodium borate (borax) or mixtures thereof, and preferably sodium silicate, is applied in solution form and maintained within the body by a wetting agent in the solution. The protective coating is being applied by a coating roller followed drying of the polystyrene body.

Abstract:
New damping (insulating) materials are based on polyvinyl chloride particles or balled up fibers which are extremely lightweight and have a bulk density of 10-200 g/l and a particle weight less than 1 g. The particles are either enveloped by sheets or combined into lightweight components by means of heat or by the addition of binders, such as adhesives, fusion (hot-melt) adhesives, curable polymers, or frothed (pre-foamed), expandable polymers.
Abstract:
Shaped part based on rigid urea formaldehyde or melamine formaldehyde foam of at least partially open cell structure and having density of 5 to 150 kgs/cu.m. The cells of the foam material adjoining the periphery of at least one external surface of the shaped part are impregnated with a silicate, and the external surface is coated with a silicate lacquer which forms a continuous top coat. A reinforcing sheet material is bonded to the top coat. The shaped part is of improved fire proofness, and compressive, tensile, and flexural strength of the foam.
