Solvay reported that Dacon Systems is increasingly specifying KetaSpire KT-851 NT polyetheretherketone as an insulator for challenging wire and cable designs targeting downhole oil well and nuclear energy applications.
Typical wireline applications used in oil and gas down-hole environments transmit data for the purposes of well intervention, data logging and reservoir evaluation, and they are often subjected to extreme temperatures and pressures. KetaSpire PEEK coatings are uniquely capable of meeting the performance demands of these applications and can enable cables to operate reliably in harsh environments. Specifically, KetaSpire KT-851 NT PEEK offers reliable long-term insulation performance up to 240°C with improved abrasion resistance vs. incumbent materials.
Solvay’s KetaSpire PEEK also resists up to 1,000 kGy of gamma radiation, which can cause conventional fluoropolymers like polytetrafluoroethylene and fluorinated ethylene propylene (FEP) to become brittle. As a consequence, KetaSpire PEEK is also becoming Dacon Systems’ first choice for coating wires and cables that transmit power or sensor data in nuclear plants. KetaSpire PEEK polymers are inherently flame retardant and bromine- and chlorine-free. They also offer excellent low smoke properties. Cables insulated with KetaSpire PEEK are being developed to meet the nuclear industry’s proposed 60-year lifetime rating, as well as the design criteria for cable function during Loss of Coolant Accident operations.
Among the highest-performing materials in Solvay’s unrivalled selection of specialty polymers, KetaSpire PEEK imparts superior resistance to fatigue, stress cracking and abrasion along with excellent strength and toughness to wire and cable coating applications. It also has excellent melt strength and can be extruded into very thin 0.025-mm coatings. Dacon can custom manufacture KetaSpire PEEK wire in American wire gauge diameters ranging from AWG 40 to 8.
