Abstract: This application relates to the use of alkyl alkanoates having molecular weights no greater than 74 as blowing agents in the production of flexible slabstock polyurethane foams. Compared to the blowing agents (fluorocarbons) widely used commercially in producing such foams, the alkyl alkanoates are more efficient in that they produce a greater volume of gas per pound of blowing agent.

Abstract: Stable catalyst compositions providing faster cure time in room temperature vulcanizing organopolysiloxane compositions containing them comprise stannous salts of branched chain alkyl carboxylic acids having from 8 to 12 carbon atoms and, as a stabilizing carrier therefor, a methyl alkyl polysiloxane fluid having hydroxy aryl substituents. The catalyst compositions are uniquely adapted to provide injectable compositions curable to low density, high compressive strength syntactic foams, useful, e.g., for custom fitting footwear to the wearer.

Abstract: THIS INVENTION RELATES TO EPOXY RESIN FOAMS HAVING GOOD PHYSICAL PROPERTIES AND BEING FREE OF SCORCHING IN THICKNESSES UP TO AT LEAST TWO INCHES. SUCH FOAMS ARE PREPARED BY CURING AN EPOXY RESIN WITH AN AMINE IN THE PRESENCE OF A PHENOLIC PROMOTER WHILE EXPANDING WITH A VOLATILE AGENT WHEREIN THE COMPOSITION HAS A W5 VALUE OF NOT LESS THAN ABOUT 270, AND AN MB VALUE OF NOT GREATER THAN ABOUT 320. WHEN THE PHENOLIC PROMOTER IS 2.5 FUNTIONAL OR HIGHER AND IS USED TO REPLACE PART OF THE AMINE CURING AGENT UNDER THE CONDITIONS DEFINED HEREIN, THE LIMIT OF MB IS INCREASED TO A MAXIMUM OF 380 AS THE PROPORTION OF PHENOLIC PROMOTER IS INCREASED. THE WS LIMIT, HOWEVER, REMAINS AT 270.

Abstract: The invention is concerned with the production of polyurethane foams of the kind formed by reaction between a polyisocyanate (which term includes a di-isocyanate) and a glycol ester of a tribasic adduct obtained by reaction between a reactive dienophile e.g. maleic anhydride and an unsaturated fatty acid or ester. The process of the invention is directed to the production of polyurethane foams of that kind which are of finer cell structure and are less friable than previous foams of this kind by a more economic method which also avoids the distillation of unreacted acids from the tribasic adduct reaction product.

Abstract: A process for the continuous manufacture of phenolic resin foam in an endless sheet which includes mixing expandable liquid phenolic resin with a blowing agent and an acid-containing curing agent, optionally with the addition of additives, and processing of the mixture in a temperature-controllable double belt press. The process also comprises cooling the phenolic resin to a temperature of from about 8* to 15*C., admixing a blowing agent under a high pressure with said resin to form a resin premix, mixing said resin premix with a curing agent resin to form a resin premix, mixing said resin premix with a curing agent and other foam additives to form a curable reaction mixture, continuously applying said mixture uniformily onto a moving substrate, covering the mixture on said substrate with a continuous protective layer, passing the covered mixture into the double belt press, and foaming the mixture under pressure until a desired sheet thickness has been obtained.
