Description
PEEK Tubes (Polyetheretherketone Tubing) – Skyjet Polymer High-Performance Extruded Stock Shapes
Skyjet Polymer specializes in the continuous extrusion of high-quality PEEK tubes using virgin polyetheretherketone resin. Our precision-extruded PEEK tubing provides excellent dimensional stability, low internal stress, and uniform wall thickness, serving as ideal semi-finished stock for machining or direct use in fluid transfer, insulation, and structural applications across demanding industries.
PEEK (polyetheretherketone) is a semi-crystalline high-performance thermoplastic valued for its outstanding balance of thermal, mechanical, and chemical properties. It supports continuous service temperatures up to 260°C (500°F), with excellent hydrolysis resistance in steam and hot water, making it a preferred alternative to metals and fluoropolymers in aggressive environments.
Key Properties and Benefits
- Thermal Stability: Continuous operating temperature of 260°C, with short-term exposure up to 310°C. Maintains rigidity and strength at elevated temperatures.
- Mechanical Strength: High tensile strength, flexural modulus, column efficiency, and creep resistance. Superior pushability, torque transmission, and buckling resistance for catheter applications.
- Chemical and Hydrolysis Resistance: Inert to most solvents, acids, bases, hydrocarbons, and steam. Ideal for prolonged exposure in harsh chemical settings.
- Low Friction and Wear: Naturally low coefficient of friction; bearing grades offer enhanced tribological performance.
- Biocompatibility: Medical-grade options comply with USP Class VI, ISO 10993, and FDA standards. Withstands repeated sterilization (autoclave, gamma, EtO).
- Electrical Properties: Excellent dielectric strength and insulation, suitable for cable sheathing and semiconductor processes.
- Low Outgassing and Purity: Minimal contamination risk in high-vacuum or analytical systems.
