Disclosed is an improved polyurethane foam having cleaning and germicidal activities. The foam is prepared by mixing together a select prepolymer reactant and water, and adding to the mixture prior to foam formation a nonionic surfactant, a quaternary ammonium compound and a silicon-based surfactant. The resulting foam is particularly useful as a disposable wiping pad for household clean-up applications.

Polyurethane foam having cleaning and germicidal activities

A fire and heat resistant container having at least the sidewall partially formed from fibrous material with an inner surface and an outer surface that has a plurality of laminae of predetermined composition and thickness arrayed in a specific manner therebetween is provided to protect an object or substance adjacent the inner surface from a fire or heat generating source adjacent the outer surface. The laminae are bonded together by a fire resistant bonding agent of predetermined thickness.

Fire and heat resistant structure

A fire and heat resistant partition having a plurality of lamina between a first side and an opposing second side is provided to protect an object adjacent the first side from a fire or heat generating source adjacent the second side, the first lamina being formed at least partially of aluminum. The first lamina is bonded to at least one ply that is formed from multiple laminae of fibrous material which are bonded to an intermediate lamina of predetermined thickness formed at least partially of aluminum.
