High-Temp PEEK & PTFE Extreme Performance Plastics

Continuous 260°C Service, Universal Chemical Resistance, Radiation Hardness & Plasma Purity.

PEEK (Polyetheretherketone) and PTFE (Polytetrafluoroethylene / Teflon) occupy the pinnacle of industrial polymer engineering. PEEK offers mechanical strength rivaling metal alloys alongside continuous 250°C heat endurance, severe autoclave resistance, and gamma radiation survivability. PTFE delivers the lowest coefficient of friction of any solid material (0.04) and universal chemical inertness across virtually all acids, bases, and organic solvents.

Frequently Asked Questions

Common engineering questions regarding tolerances, material traceability, and turnaround for High-Temp PEEK & PTFE Extreme Performance Plastics.

Why is PEEK so expensive compared to standard engineering plastics? +
PEEK is an ultra-high performance aromatic polymer requiring complex high-temperature synthesis. It retains full mechanical strength at 200°C where ordinary plastics liquify.
Can PEEK replace metal components? +
Yes. PEEK is frequently used to replace titanium, aluminum, and stainless steel in aircraft brackets and medical implants, reducing weight by 60% with zero galvanic corrosion.
How do you prevent dimensional creep when machining PTFE? +
PTFE has a high thermal expansion coefficient and memory effect. We perform roughing, stress-relief resting at 23°C, and light finish passes using razor-sharp diamond tools.
Is PEEK safe for medical human implantation? +
Medical-grade PEEK (such as PEEK-OPTIMA) is fully biocompatible, radiolucent (transparent on X-rays), and extensively certified for permanent orthopedic spinal implants.
