PEEK - Polyetheretherketone
Learn all about properties and what Dechengwang can do for your PEEK components.
Properties and Performance of PEEK
PEEK is a high-performance engineering plastic with outstanding chemical resistance, excellent mechanical strength and dimensional stabilization.
- Unique physical, thermal & electrical properties
- Ideal stainless steel replacement
- Lightweight
- Biocompatibility
- High tensile strength
- High Temperature performance: continue 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 module is increased. This makes it ideal for applications requiring increased stability, strength and rigidity at temperatures above 300°F.
