    • Methods of manufacturing an electrical connector for use in a downhole tool are described. The methods include placing or molding a dielectric body around a conductor, thereby forming an electrical connector. The dielectric body is composed of a composition, which itself contains a polyetherketoneketone or a derivative of polyetherketoneketone. The placement of the dielectric body around the conductor can be accomplished by molding the body around the conductor, for example, by molding techniques such as extrusion, injection molding, pressure molding, compression molding, and casting. An electrical connector for use in a downhole tool is also provided. The electrical connector countains a dielectric body and a conductor. The dielectric body includes a composition, which itself is composed of a polyetherketoneketone or a derive of a polyetherketoneketone. The electrical connector of the invention is adapted for use in a downhole tool.
    • 描述制造用于井下工具的电连接器的方法。 所述方法包括将电介质体放置或模制在导体周围,从而形成电连接器。 电介质体由本身含有聚醚酮酮或聚醚酮酮衍生物的组合物组成。 介电体在导体周围的放置可以通过将本体围绕导体模制,例如通过诸如挤出,注射成型,压力成型,压塑和铸造的成型技术来实现。 还提供了一种用于井下工具的电连接器。 电连接器测量电介质体和导体。 介电体包括本身由聚醚酮酮或聚醚酮酮衍生物组成的组合物。 本发明的电连接器适用于井下工具。

    • Included within the scope of the invention is an article of cured fluoroelastomer composition bonded to an inert substrate. The cured fluoroelastomer composition includes a fluoropolymer, a silica, and an acrylate compound. The fluoroelastomer composition is bonded to the inert substrate with a bind having a bond durability of at least about 1500 pounds load at 20° C. The inert substrate may be a metal substrate or a ketone-based polymer substrate.Also included are methods of bonding a fluoroelastomer composition to an inert substrate that may be, for example, a metal substrate or a ketone-based polymer substrate. The methods include contacting a curable fluoroelastomer composition to an inert substrate and curing the fluoroelastomer composition to form a bond between the composition and the inert substrate. The curable fluoroelastomer composition of the methods includes an acrylate compound, a curing agent, silica, and a fluoropolymer that comprises at least one cure site monomer.
