Product Overview

PEEK is a high-performance engineering plastic with outstanding chemical resistance, excellent mechanical strength, and dimensional stabilization. It has excellent mechanical and long-term chemical resistance properties that are retained to high temperatures, and is highly resistant to thermal decomposition or thermolysis.

Properties and Performance of PEEK

• Unique physical, thermal & electrical properties
• Ideal stainless steel replacement
• Lightweight
• Biocompatibility
• High tensile strength
• High temperature performance: continuous use to +240°C (464°F), up to +260°C (500°F)
• Low coefficient of friction and high wear resistance
• Chemically resistant to common chemicals including acids, salts, solvents, oils, and steam
• Low outgassing, low particle generation, and inherent purity

Enhanced Mechanical Properties with Filled Grades

Standard PEEK virgin grade is suitable for laboratory and medical use. After being reinforced with glass fibers and carbon, its expansion rate is significantly reduced and the flexural modulus is increased, making it ideal for applications requiring increased stability, strength, and rigidity at temperatures above 300°F.

Despite the high price of this high-performance engineering thermoplastic polymer, the added benefits PEEK brings — being lightweight, robust, and able to survive longer in harsh environments — are invaluable.

Applications

Thanks to its excellent mechanical and long-term chemical resistance properties, PEEK and its composites are widely used in aerospace, automotive, biomedical, high-temperature electrical, and structural applications.
