PEEK is a high-temperature resin used in safety-critical industries such as medical, aerospace and automotive. The high-performance material offers good chemical and heat resistance, as well as flame retardancy, and provides excellent strength and dimensional stability.
Applications: Cable insulation, piston parts, bearings, valves, pumps, medical implants, ultra-high vacuum applications.
Behavior: If PEEK proves too expensive, Ultem or PPSU is more budget-friendly alternatives.
