PEEK (polyetheretherketone) is a robust, rigid thermoplastic material. Because PEEK has superior chemical resistance – as well as resistance to steam and water, it is often used in applications where performance at elevated temperatures is required.
PEEK polymer is a linear, aromatic, semi-crystalline thermoplastic, widely regarded as one of the highest performing thermoplastic materials in the world. It offers a unique combination of properties:
Low Outgassing and Extractables – where high purity and low contamination levels are key requirements.
RoHS Compliance – the majority of grades comply with European RoHS (Restriction of Hazardous Substances) legislation that restricts the use of six hazardous materials found in a wide range of products including electrical and electronic products.
Exceptional Abrasion Resistance – very hard, tough, and scratch resistant.
Excellent Mechanical Properties – including wear, creep and cut through resistance. Extremely durable at high temperatures.
Excellent Wear Surface – an excellent wear counterface to hard surfaces like steel and ceramics. Non-galling with low particulation and nonsloughing.
Good Lubricity – offers a smooth and uniform surface.
High Load Bearing Surface – one of the strongest thermoplastic coatings on the market. Very resistant to creep and flow caused by compression.
Excellent Radiation Resistance – Some formulations can withstand high doses of Gamma radiation (> 109 Rads) without embrittlement.
High Temperature Performance – one of the highest performing polymers available where continuous high temperature performance up to 260°C (500°F) is required. Withstands lead-free soldering temperatures.
Very Good Chemical Resistance – insoluble in all common solvents. Excellent resistance to acids, bases, hydrocarbons, salts and steam.
Good Electrical Insulative Properties – very stable electrical insulative properties over a wide range of temperatures, frequencies and humidities.
FDA Compliance – the majority of VICOTE grades can be used in environments involving food contact.
Low Moisture Absorption and Excellent Hydrolysis Resistance – properties are unaffected by exposure to water, humidity and steam.
