Abstract: A CNS millbase dispersion, comprises a solvent and up to 0.5 wt % of at least one CNS-derived material dispersed in the millbase dispersion and selected from the group consisting of: carbon nanostructures, fragments of carbon nanostructures, fractured carbon nanotubes, and any combination thereof. The carbon nanostructures or fragments of carbon nanostructures include a plurality of multiwall carbon nanotubes that are crosslinked in a polymeric structure by being branched, interdigitated, entangled and/or sharing common walls, and the fractured carbon nanotubes are derived from the carbon nanostructures and are branched and share common walls with one another. A Brookfield viscosity of the dispersion measured at room temperature at 10 rpm is less than 3000 cP.

Abstract: Described herein is a method for preparing polyurethane foams, including (1) placing a reaction mixture into a pressurizable chamber, and (2) polymerizing the reaction mixture at an additional pressure, where the reaction mixture comprises an isocyanate, an isocyanate-reactive compound and a blowing agent, and the reaction mixture is placed into the pressurizable chamber at a packing factor of 2.0-4.0. Also described herein is a polyurethane foam prepared by such a method.

Abstract: Described herein is a polyurethane foam prepared with certain polytetrahydrofurans and optional polyether polyols. The polyurethane foam is characterized by low hardness increase at low temperature as compared with conventional polyurethane foam, and is suitable for use in products which can be exposed to low temperature such as snow boots.

Abstract: Because the back-and-forth movement by hand is slower and more strenuous than the leftward-and-rightward swinging, a handheld image-tracking device, which can be applied to an optical mouse or a handheld scanner, uses a rectangle-shaped sensing array to save area of the sensing array and lower down the production cost for the device by reasonably reducing the back-and-forth sensing area for the sensing array; and, so, an amount and time spent for a data comparison in the device is lessened.
