Abstract:
A novel flame retardant and fire extinguishing product for preventing and fighting fires is disclosed herein. The product is thixotropic and non-toxic, and comprises water, one or more flame retardants, one or more stabilizers, and one or more preservatives. In some embodiments, the product further comprises one or more thickeners, one or more binders, one or more fining agents, one or more firming agents, one or more water retention agents, one or more water-soluble fluoropolymers or other water-soluble polymers with similar properties, one or more detergents, and/or one or more surfactants. The product may be used as a flame retardant to prevent fires and in active firefighting. The product may be biodegradable in a natural environment, may be readily cleaned off equipment and materials using water, and may also provide other features which render it safe for the environment as compared to other commonly used products in fire prevention and firefighting.

Abstract:
Die Erfindung betrifft einen elastomeren Körper (1) zur Schwingungsdämpfung und/oder Federung umfassend mindestens eine Schicht einer flammenhemmenden Beschichtung (3), die mindestens einen Abschnitt des Körpers (1) bedeckt. Der elastomere Körper umfasst expandierbares Graphit als flammenhemmende Substanz und der Anteil an expandierbarem Graphit in der Beschichtung (3) beträgt weniger als 15 Gew.%.
Abstract:
An apparatus and method for forming a fire retardant-treated fiber product is provided, A first nip is defined by a pair of juxtaposed processing members, and is configured to receive a fiber product therethrough. At least one of the processing members comprises an incisor member extending from a processing surface thereof, and interacting with and altering a surface of the fiber product directed through the first nip. A second nip is defined by a pair of juxtaposed compression members, and is configured to receive the fiber product therethrough. Compression surfaces of the compression members cooperate to compress the surface of the fiber product within an elastic range associated therewith. At least one of the first and second nip is arranged to receive a fire retarding solution such that the fiber product is interacted therewith at least upon entering the at least one of the first and second nip.
Abstract:
A flame-retardant metal-coated fabric which not only has excellent electromagnetic-wave-shielding properties but has a high degree of flame retardancy without the necessity of containing a halogen compound or antimony compound. It is soft and suffers no deterioration of the metal coating even in long-term use. The flame-retardant metal-coated fabric comprises a metal-coated fabric and, formed on at least one side thereof, a flame-retardant coating film comprising a mixture (F) of a flame retardant (A) selected among ammonium polyphosphate, etc., a flame-retardant aid (B) selected among melamine, etc., a blowing agent (C) selected among heat-expandable graphite, etc., a phosphoric ester (D), and a thermoplastic resin (E) having a melting point of 70-130°C, and is characterized in that the weight proportion of (A):(B):(C):(D):(E) is in a specific range.
Abstract:
A flame retardant, electromagnetic interference (EMI) shielding gasket construction. The construction includes a resilient core member formed of a layer of a foamed polymeric material which is rendered flame retardant by being immersed a solution of a flame retardant composition and alternately compressed and relaxed while so immersed to effect the uptake the solution into the material.
Abstract:
The invention relates to a nano composite for thermal insulation especially for fireproofing purposes, which can be obtained by combining (A) at lest 35 wt. % of nanoscaled, optionally surface modified particles of an inorganic compound; (B) 10-60 wt. % of a copound with at least two functional groups which can react and/or interact with surface groups of nanoscaled particles (A), (C) 1-40 wt. % of water and/or an organic solvent, which has no functional groups or only one which is defined in (B), wherein the above-mentioned percentages relate to the sum of constituents (A) (B) and (C) and (D) = 0-10 wt. % (in relation to the nano composite) of additives.
Abstract:
A chemically active composition containing an iron (II) compound, ascorbic and/or citric acid, and alum, with the weight ratio of ferrous ion in the iron (II) compound to ascorbic or citric acid being 1:0.02 to 0.30 (with ascorbic acid) or 1:0.01 to 0.80 (with citric acid). This composition is used as an aqueous solution or in a solid form as a deodorant, food freshness-maintaining agent, plant growth accelerator, and flameproofing agent, and provides a multi-functional material.
