20100029825 | POLYIMIDE RESINS FOR HIGH TEMPERATURE WEAR APPLICATIONS - Polyimide resin compositions that contain an aromatic polyimide, graphite and a sepiolite filler, or a mixture of a sepiolite filler and a kaolin filler, are found to exhibit low wear and high thermal oxidative stability. Such compositions are especially useful in molded articles that are exposed to wear conditions at high temperatures such as aircraft engine parts. | 02-04-2010 |
20100043522 | METHOD FOR EVALUATING HIGH TEMPERATURE WEAR LIFE - A method is provided for evaluating relative wear life polymeric specimens intended for use at high temperature under high wear conditions. | 02-25-2010 |
20100112063 | METHOD FOR PREPARING A HYDROGEL ADHESIVE HAVING EXTENDED GELATION TIME AND DECREASED DEGRADATION TIME - A method for extending the gelation time of an oxidized polysaccharide to react with a water-dispersible, multi-arm amine to form a hydrogel is disclosed. The extension of the gelation time is accomplished by using a chemical additive. The method also extends the time for the hydrogel to become tack-free, and may also be used to decrease the degradation time of the hydrogel. The chemical additive reacts with the functional groups of the oxidized polysaccharide or the water-dispersible, multi-arm amine, thereby reducing the number of groups available for crosslinking. The use of the resulting hydrogel for medical and veterinary applications is described. | 05-06-2010 |
20110098409 | COMPOSITIONS AND ARTICLES FOR HIGH-TEMPERATURE WEAR USE - Disclosed herein are compositions and articles that are useful in environments exposed to heat, wear, and oxidizing agents, which are improved by means of specific kinds of carbon filaments. The compositions and articles comprise high-temperature polymer, high-temperature filler, and a mixture of carbon filament, wherein said mixture of carbon filament comprises multiwall axial carbon filament. | 04-28-2011 |
20110265949 | TEMPERATURE SWITCHABLE ADHESIVES COMPRISING A CRYSTALLIZABLE OIL - Temperature switchable adhesives formed by combining a pressure sensitive adhesive, which does not exhibit temperature switchable properties, with a crystallizable oil are described. These temperature switchable adhesives exhibit a sharp reduction in peel strength when the temperature is raised above the switching temperature. The adhesive properties of these adhesives may be readily tuned by adjusting the ratio of the elastomer, tackifier, and the crystallizable oil, and by choosing different crystallizable oils. The temperature switchable adhesives have use in medical, consumer, and industrial applications. | 11-03-2011 |
20120021215 | TEMPERATURE SWITCHABLE ADHESIVE ASSEMBLIES WITH TEMPERATURE NON-SWITCHABLE TACK - Disclosed herein are temperature switchable adhesive assemblies, which maintain tack above and below the switching temperature. The temperature switchable adhesive assemblies comprise a backing, a first adhesive layer comprising a temperature switchable pressure sensitive adhesive disposed on the backing, and a second adhesive layer comprising a non-switchable pressure sensitive adhesive disposed on the first adhesive layer. The temperature switchable adhesive assemblies have use in medical, consumer, and industrial applications. | 01-26-2012 |
20120235071 | POLYIMIDE RESINS FOR HIGH TEMPERATURE WEAR APPLICATIONS - Polyimide resin compositions that contain an end-capped rigid aromatic polyimide, graphite and carbon filaments are found to exhibit low wear at high temperatures.
