PEEK Material Temperature Range

Polyetheretherketone (PEEK) is a high-performance thermoplastic known for its exceptional thermal stability and mechanical properties across a wide temperature range.?

Here are the key temperature characteristics of PEEK:

Temperature Ranges of PEEK

Glass Transition Temperature (Tg): PEEK has a Tg ranging from?143°C to 165°C?(approximately?289°F to 329°F) depending on the specific grade of the material.

Melting Temperature (Tm): The melting point of PEEK is typically around?341°C to 343°C?(about?646°F to 649°F) which allows it to be processed at high temperatures.

Continuous Use Temperature: PEEK can be used continuously at temperatures up to?260°C?(about?500°F) without significant degradation of its mechanical properties.

Short-term Use Temperature: It can withstand short-term exposure to temperatures as high as?300°C?(approximately?572°F) for limited periods.

Low-Temperature Performance: PEEK maintains satisfactory performance at low temperatures, functioning effectively down to?-50°C?(-58°F) and, for brief durations, even down to?-100°C?(-148°F) without losing its structural integrity.

PEEK's ability to perform under such diverse temperature conditions makes it suitable for applications in various industries, including aerospace, automotive, medical, and electronics, where both high thermal resistance and mechanical strength are critical.
