Patent number: 8852487Abstract: A method for injection molding a thermoplastic composition that contains a polyarylene sulfide and a boron-containing nucleating agent is provided. By selectively controlling certain aspects of the polyarylene sulfide and nucleating agent, as well as the particular manner in which they are combined, the crystallization properties of the resulting thermoplastic composition can be significantly improved. This allows the “cooling time” during a molding cycle to be substantially reduced while still achieving the same degree of crystallization. The cooling time can be represented by the “normalized cooling ratio”, which is determined by dividing the total cooling time by the average thickness of the molded part.Type: GrantFiled: December 10, 2012Date of Patent: October 7, 2014Assignee: Ticona LLCInventors: Ke Feng, Peter Radden, Michael Schafer

Patent number: 8853313Abstract: An injection moldable, thermally conductive polymer composition that has ultra low CTE properties is provided. The composition is suitable both for substrate applications in high precision electronics assemblies as well as over molding applications in conjunction with ceramic substrates. The composition includes a base polymer matrix material loaded with thermally conductive filler, which imparts thermal conductivity to the polymer matrix while also maintaining or enhancing the dielectric properties of the base polymer. The resultant composition exhibits CTE properties in the range of between 9 ppm/° C. and 2 ppm/° C., exhibits an optical anisotropy of below 1.5, and a thermal conductivity of greater than 2 W/m° K. The composition is suitable for use in over molding applications in conjunction with virtually any suitable electronics substrate material without the introduction of mechanical stresses produced by large CTE differentials.Type: GrantFiled: May 30, 2012Date of Patent: October 7, 2014Assignee: Cool Options, Inc.Inventor: James D Miller
