KetaSpire® KT-820 GF30

Technical Datasheet | Supplied by Syensqo
KetaSpire® KT-820 GF30 by Solvay is a medium flow, flame retardant, polyetheretherketone (PEEK) resin reinforced with 30% glass fiber. It is a semi-crystalline, radiotranslucent grade providing high heat-, chemical-, fatigue- and radiation (gamma) resistance. Exhibits good sterilization through autoclave, E-beam, ethylene oxide, heat, steam & radiation, good mechanical properties and steam resistance. Offers higher stiffness & strength than unreinforced PEEK resins, good dimensional stability, high purity, good processability, low CLTE, high limiting PV properties and excellent dielectric properties with low loss at high temperatures and frequencies. It can be processed by injection molding, profile extrusion and machining. Recommended for healthcare/medical applications like hospital goods, surgical instruments, dental instruments, electrical/electronic applications like connectors, aircraft applications, transportation, seals, film, chemical processing and oil/gas applications. KetaSpire® KT-820 GF30 complies with FAA FAR 25.853a, ISO 10993, MIL P-46183 Type II Class 3 and RoHS.
