What is PEEK Plastic? An Introductory Guide

When it comes to applications that require high-performance plastic, PEEK is often a top recommendation. You may be wondering, what is PEEK plastic and why is it so popular? We often refer to PEEK as the “powerhouse polymer” because of its unique combination of outstanding properties that make it suitable for a wide array of uses across nearly every industry.

What is PEEK Plastic?

PEEK stands for “polyetheretherketone,” making it part of the broader family of ketone polymers. The unique chemical structure of this thermoplastic makes it incredibly strong and dimensionally stable both under load and in the harshest environments. The key characteristics of PEEK plastic include:

PEEK plastic is also available in a variety of grades that offer enhanced properties for specific use. For example, glass-fiber-reinforced PEEK has a reduced expansion rate, increased flexural modulus, and excellent electrical and thermal insulation characteristics. Likewise, carbon-fiber-reinforced PEEK has the highest strength and stiffness properties; outstanding wear resistance and load-carrying capabilities; and higher thermal conductivity.

PEEK plastic ranks high for:

Clients are often surprised at the cost of PEEK plastic, as it is one of the most expensive polymers on the market. But this cost is a reflection of its quality. Due to PEEK’s high temperature resistance and high tensile strength, PEEK plastic machines more like a metal than a polymer. This can make it difficult and costly to process through methods such as injection molding, but in its solid state PEEK is readily machinable by CNC milling machines.

What is PEEK Plastic Used For?

PEEK plastic is suitable for a wide array of applications, such as:
