Strong, stiff plastic with outstanding chemical resistance; performs over a wide range of temps

1、About PEEK

PEEK plastic (polyetheretherketone) is a high-performance engineering plastic with outstanding resistance to harsh chemicals, and excellent mechanical strength and dimensional stability. It offers hydrolysis resistance to steam, water, and sea water. PEEK material has the ability to maintain stiffness at high temperatures and is suitable for continuous use at temperatures up to 338oF (170℃). This engineering plastic has a proven track record in challenging environments such as aerospace, oil and gas, food and beverage processing, and semiconductor.

4、Why Choose PEEK?

PEEK can be melt-processed without creating corrosive gasses, making it extremely safe and effective to use with injection molding and additive manufacturing. PEEK’s high melt point also opens it up to CNC machining possibilities, as fast-moving tools can cut PEEK without causing any melting.

Manufacturing PEEK using any of these methods results in good mechanical performance and consistency between parts. PEEK can also support complex designs and geometries with additive manufacturing — in fact, PEEK offers a significantly higher tensile strength and tensile modulus than polyethersulfone (PES), a primary material competitor.

PEEK is more heat resistant than PES and polyphenylene sulfide (PPS), another material product teams often swap out for PEEK. While PES can be used up to 220ºC and PPS can stand continuous use up to 250ºC, PEEK doesn’t even begin to melt at these temperatures.  PEEK offers similar water and chemical resistance to PPS while boasting increased temperature control, resulting in total out performance across high-heat applications.
