PEEK, also known as polyetheretherketone, is a high-performance engineering plastic with exceptional resistance to corrosive substances as well as superior mechanical strength and dimensional stability. It offers resistance to hydrolysis in sea water, water, and steam. PEEK is suited for continuous use at temperatures up to 338oF and has the capacity to sustain stiffness at high temperatures (170oC). In demanding areas like semiconductor, oil and gas, food and beverage processing, and aerospace, this engineering plastic has an established track record.

PEEK IS USED COMMONLY FOR:

• Semiconductor machinery components
• Aerospace parts
• Bushings, bearings, seals, and back-up rings
• Pump and valve components
• Vacuum wand handles
• Down hole electrical connectors
• Medical instrument parts
• Food processing machinery components

Sturdy, stiff plastic that operates well across a wide temperature range and has excellent chemical resistance.

Tech Tip: Using a filled grade of a stable (low CTE) base polymer is best practice when polymers are needed for applications that include significant temperature swings. PEEK is a promising contender for applications needing plastics with CTEs as close as feasible to those of metals because when fillers are added to highly stable base polymers like PEEK, the resulting composites display extremely low CTE values.
