Abstract: The present technology provides a method of manufacturing a polyurethane foam having a low thermal conductivity from a foam formulation comprising a polyol, an isocyanate, a polyurethane catalyst, a surfactant, water, and a siloxane rich composition. The siloxane rich composition may act as a nucleating agent to reduce the cell size of the foams and may reduce its thermal conductivity.

Abstract: A heater comprises a plurality of zones with at least two zones having a variable power density gradient different from one another. The heater having zones of different variable power density gradients allows for controlling the heat output and temperature profile of the heater in one or more directions of the heater. The heater can be used, for example, to control the temperature profile in a vertical direction.

Abstract: A process and composition for the hydrosilylation of an unsaturated compound comprising reacting (a) a silyl hydride with (b) an unsaturated compound in the presence of (c) a platinum compound and (d) a cyclodiene, with the proviso that when the unsaturated compound is a terminal alkyne, the silyl hydride is other than a halosilane. The process and composition optionally comprise an inhibitor (e). The process and composition may be employed to form a variety of hydrosilylation products.
