Abstract
A liquid crystalline polymer composition that is thermally and/or electrically conductive and has a reduced tendency to create a static electric charge during a molding operation is provided. More particularly, the composition contains carbon fibers distributed within a liquid crystalline polymer matrix. Through the use of carbon fibers having relatively high purity, high temperature sizing agent, and/or various process parameters, molded parts can be produced having excellent characteristics while minimizing the amount of carbon fibers contained within the polymer matrix.
Claims13
A molded part that comprises a polymer composition, the polymer composition comprising carbon fibers distributed within a liquid crystalline polymer matrix that constitutes from about 25 wt. % to about 95 wt. % of the composition, wherein carbon fibers constitute from about 0.5 wt. % to about 20 wt. % of the composition, and wherein the molded part exhibits a surface resistivity of about 1×1014 ohms or less as determined in accordance with IEC 60093, dielectric constant of about 5 or more as determined at a frequency of 10 MHz, and dissipation factor of about 1 or less as determined at a frequency of 10 MHz.
