A structurally stable material, PEEK can withstand extreme temperatures, features low water absorption and lives up to the most stringent requirements in food declarations.

A strong high-tech plastic

PEEK is available in four categories, each with its own attributes: PEEK-1000, PEEK-HPV (black), PEEK-GF30 and PEEK-CA30. PEEK is particularly well-suited to use in bearings, cogs, hydraulic impellers and pump parts to severe loads. PEEK is known for its mechanical attributes, as well as its chemical resistance and approval for use in food applications. As a result, PEEK is widely used in the engineering, electronics, food, chemical and medico-technical industries.

The composition of the material lives up to EU directives and American FDA regulations regarding the use of plastic in contact with foods. These qualifications make the material a popular choice in the food and pharmaceutical industries.

PEEK can be welded using standard methods such as ultrasound and friction welding, although it is important to take the high melting point of the material – 343°C – into notice when choosing the joining method. PEEK is hardly auto-combustible and readily self-extinguishing. The material is classified V0 and generates little smoke. PEEK complies with the RoHS directive. Peek can be glued using a variety of adhesives such as cyanoacrylate, epoxy and silicone. PEEK is resistant to almost all organic and inorganic fluids. The only known medium that will dissolve PEEK is concentrated sulphuric acid. The material is also affected by smoking, concentrated nitric acid.

PEEK is widely used in industrial applications. The mechanical attributes as well as the chemical resistance and food approval make PEEK particularly well-suited to: bearings, cogs, screw wheels, hydraulic parts, pump components, wear rings, and scrapers to severe loads, and for applications in the chemical and food industries.
