ABOUT THE PRODUCT

Product Description

Product Description-Polyether ether ketone CAS#29658-26-2

Polyether ether ketone (PEEK), alternatively named poly(oxy‑1,4‑phenylene‑oxy‑1,4‑phenylene‑carbonyl‑1,4‑phenylene), is a semi‑crystalline aromatic thermoplastic polymer featuring outstanding thermal stability, mechanical strength and broad chemical resistance. It is available as granules, powder or semi‑finished stock shapes.

Product Applications-Polyether ether ketone CAS#29658-26-2

In medical applications, it can be machined into implant parts, surgical instruments and sterilizable devices as an alternative to metal components. Industrially, it manufactures semiconductor jigs, automotive precision parts, oil‑gas seals, gears, bearings and chemical‑resistant equipment parts. It can be processed by injection molding, extrusion, CNC machining and additive manufacturing; unfilled, glass‑filled and carbon‑fiber‑reinforced grades are commercially available for different performance requirements.
