Product Specification

PEEK Rods and Sheets

PEEK rods and sheets are high-performance engineering plastic stock shapes designed for machining components that require high mechanical strength, heat resistance, dimensional stability and chemical resistance.

PEEK, or polyetherether ketone, combines the rigidity and strength of an engineering plastic with excellent performance in demanding temperature, pressure and chemical environments. It is widely used as an alternative to metal and conventional plastics in applications where lower weight, electrical insulation, wear resistance or corrosion resistance is required.

We supply PEEK round rods in diameters from 2 mm to 250 mm, with a standard length of 1000 mm. PEEK sheets are available in thicknesses from 1 mm to 100 mm, with a standard sheet size of 620 × 1220 mm.

Custom cutting, non-standard dimensions and CNC-machined components can be supplied according to drawings or application requirements.
