Abstract: The invention is directed to polyimide based adhesives having a coefficient of thermal expansion (“CTE”) equal to or below 50 ppm/° C. The adhesives of the present invention contain a polyimide base polymer present in the overall adhesive in an amount from 25 to 95 weight percent. The polyimide base polymer has a glass transition temperature (“Tg”) in a range of from about 150 to about 300° C. and typically has a coefficient of thermal expansion above 50 ppm/° C. The polyimide based adhesives of the invention also contain an aramid micro fiber filler in an amount from 5 to 75 weight percent, based upon the total weight of the polyimide based adhesive. The fiber filler can be used to lower CTE of the overall adhesive to match (or nearly match) the CTE of other materials like metal, silicon wafers, other polymers (including polyimide) and the like.

Abstract: The present invention provides an abrasion resistant composition comprising fluoropolymer and an effective amount of micropulp to increase the abrasion resistance of an article such as a film formed from the composition by at least 25% as compared to film formed from the fluoropolymer by itself. In an especially preferred embodiment, the composition also contains an effective amount of pigment to further increase the abrasion resistance of film formed from the composition as compared to film formed from the fluoropolymer by itself. The invention is especially useful for films formed on a fuser roll.

The process includes contacting organic fibers with a medium comprising a liquid component and a solid component, agitating the medium and the organic fibers to transform the organic fibers into the micropulp dispersed in the medium. If desired, the slurry of the micropulp in the liquid component can be used or the micropulp can be separated from the medium. The micropulp can be readily incorporated into coating compositions such as those used in automotive OEM or refinish applications. The micropulp can also be incorporated into powder coating applications or as a thixotrope or reinforcement in polymer formulations.
