20110120645 | ENERGY-ACTIVATED ROOM TEMPERATURE-PUMPABLE POLYMER COMPOSITIONS AND DEVICES FOR ACTIVATING AND DISPENSING THE SAME - Energy-activated room temperature-pumpable polymer compositions, devices for activating and processing the same into solid cellular or non-cellular polymeric materials that can be used as adhesives, sealants, coatings or gasket materials, and methods of making and using the same. The compositions according to the invention include solid particles that include one or more polymers, which are emulsified, dispersed or suspended in a liquid carrier together with at least one processing aid, such as a reactive blowing agent, a low molecular weight surfactant, a high molecular weight surfactant, one or more compounds found in latex paint, starch, cellulosic derived products and combinations of two or more thereof. The processing aids provide various benefits including, for example, reduced density, improved process hygiene, improved foam stability, faster bonding times and/or lower processing temperatures. | 05-26-2011 |
20090133826 | PUMPABLE HEAT-PROCESSABLE LIQUID DISPERSIONS FOR FORMING FUSED THERMOPLASTIC SOLIDS - A composition that includes first solid particles including a first polymer, second solid particles including a second polymer, and a liquid into which the first solid particles and the second solid particles are dispersed, wherein the composition is a pumpable liquid dispersion at room temperature, wherein the first polymer, the second polymer and the liquid become compatible and form a substantially homogeneous molten blend when the pumpable liquid dispersion is heated and mixed, wherein the substantially homogeneous molten blend forms a fused thermoplastic solid when the substantially homogeneous molten blend cools to a solidification temperature, wherein the liquid is retained in the fused thermoplastic solid and wherein the first polymer is at least partially incompatible with the liquid retained in the fused thermoplastic solid. | 05-28-2009 |
