Abstract: A synthetic fire-resistant resin includes one or more of a polycarbonate resin material, and/or a polyester resin material mixed with a flame-retardant, such as a bis-diphenyldiphosphate flame-retardant. Alternatively, a mixture of polycarbonate resin material mixed with polyester resin material can be capped with a fire-resistant film. The resin sheet can be made at a thickness such that the resin sheet is structurally useful as a conventional building material. Furthermore the resin sheet can be made transparent, translucent, or colored, as desired for architectural purposes. The resin sheet further has a Vicat temperature that renders the extruded resin sheet easy to work with using conventional manufacturing techniques, and strong enough to be used in a wide variety of indoor and outdoor environments. In one implementation, fire-resistant resin sheets can be combined with a decorative image layer to form a decorative panel that can be used in Class A building environments.

Abstract: The present invention concerns finely divided particles of compounds that provide flame retardancy and/or smoke suppressant properties to fibers, textiles, polymeric articles, paper, paint, coating and insulation. More particularly, the present invention concerns colloidal-sized particles of hydrated salts, organic phosphates, metal borates, polyamides, solid halogenated flame retardants with a melting point greater than 250.degree. C., molybdenum compounds, metallocenes, antimony compounds, zinc compounds, bismuth compounds and other solid chemicals which act as flame retardants or smoke suppressants. The present invention also concerns various milling processes to reduce these materials to colloidal sizes and to disperse them in water, organic liquids and meltable solids.

Abstract: A process for passivating contaminating metal on a hydrocarbon cracking catalyst is provided. The catalyst is contacted within a hydrocarbon catalytic cracking unit with a stabilized dispersion. The dispersion comprises a fluid vehicle, a dispersion agent, and finely milled particles of one or more metals or metal compounds for passivation of metal-contaminated cracking catalysts. The dispersion is preferably produced by a process wherein an agitated media mill is loaded with comminuting media, fluid vehicle, dispersion agent and particles of a metal or metal compound for passivation of metal-contaminated cracking catalysts. The comminuting media, fluid vehicle, and particles are then agitated until the particles are reduced in size by at least 10% and have a volumetric average particle size of less than 0.5 microns.
