Abstract: A method and apparatus for the continuous production of flexible open cell polyurethane foam, where a process air stream is drawn through the interior of the foam material after it has completed its rise to thereby accelerate the cooling of the foam material. The process air stream contains vaporized constituents which are removed by the steps of:(a) collecting the air stream from the foam material;(b) passing the air stream into an adsorption expansion chamber having a cross-sectional area adapted to reduce the flow rate of the air stream;(c) passing the air stream into an adsorption chamber;(d) passing the air stream through at least one activated carbon char filter bed located in the chamber at a flow rate that is adapted to provide sufficient residence time for the removal of the vaporized constituents drawn from the foam material; and(e) discharging the treated air stream into the atmosphere.

Abstract: This invention relates to a process and apparatus for removing fine particulate matter and vapors from a process exhaust air stream, and particularly those emitted during post-production curing or post-treatment of foamed plastics, such as polyurethane foam, in which the exhaust air stream is passed through a transfer duct into which is introduced a water spray in the form of a mist of fine droplets in an amount which exceeds the saturation point; thereafter the exhaust air stream is introduced into a filter chamber having a cross-sectional area that is substantially greater than that of the transfer duct, and the exhaust air stream passes through at least one, and preferably a plurality of high surface are a filters, whereby a portion of the water is removed from the exhaust air stream and collected in the filter chamber prior to the discharge of the exhaust air stream into the environment.

Abstract: Improved ignition resistant, flexible, open-celled polyurethane foams are described. The foams are formed in situ from the reaction, in the presence of a catalyst, of an isocyanate, one or more blowing agents including water, a foam stabilizer, a polyether polyol, melamine, and a standard flame retardant additive. Preferred standard flame retardants are halogenated phosphorus esters and a blend of about 80 to 85% pentabromodiphenyl oxide in an aromatic phosphate plasticizer. The melamine is present in the foam formulations in an amount of from 30 to 40 parts by weight per 100 parts by weight of polyol. The standard flame retardant is present in an amount of from 15 to 25 parts by weight per 100 parts by weight of polyol. The compositions of the invention are particularly suitable for use in furniture, bedding, and carpet padding.

Abstract: A rollout apparatus for rolling trapped air from a resin impregnated fiber mat has two carriage assemblies mounted for reciprocated movement in opposite direction. Each of the carriage assemblies carries depending rollers that engage an impregnated fiberglass mat laid on a mold. The carriage assemblies oscillate simultaneously in opposite directions so that the turning forces generated by the receiprocation cancel each other, thus providing a smooth vibration-free mechanism.
