PEEK (polyether ether ketone) is a high-performance thermoplastic used in a wide range of applications in the engineering, aerospace, food and beverage, and oil and gas industries.PEEK performs well in high-temperature, high-pressure environments.PEEK has a number of unique properties that make it one of the most commonly used polyketone polymers.

Properties and Benefits of PEEK Materials
PEEK is probably the closest thing to a preferred material for a variety of industries and applications. It offers considerable durability in harsh environments, and its glass and carbon reinforced grades are among the stronger of all thermoplastics at room temperature. In addition, unfilled grades of PEEK are highly resistant to most chemically aggressive environments, including high-pressure steam.
To fully appreciate PEEK's many valuable properties, it has the following characteristics:
Extensive processability - PEEK is easy to process and is well suited for high-volume commercial applications.PEEK components can be injection molded into extruded and injection molded billet shapes using large-volume molds and made from strip Blanks or films can be stamped and processed.PEEK's high molecular weight and melt stability allow it to be extruded into large cross-sections such as rods larger than 200mm, plates up to 100mm and tubes with wall thicknesses up to 50mm.PEEK is one of the few high-performance thermoplastics that can handle the extensive processing required to produce complex components.
High Wear Resistance - PEEK is known for its all-around wear resistance, including abrasion, friction and fatigue. In addition, with PTFE graphite and carbon fibers made of PEEK provide lower wear rates under high-pressure speed conditions.
Excellent Thermal Properties - PEEK has high strength and temperature resistance and does not melt until it reaches approximately 343°C. This means that it can be used at temperatures as high as 250°C. This means that it can be used at temperatures up to 250°C. As a result, it can be used for long periods of time at temperatures up to about 250°C and significantly higher for short-term use - far beyond the capabilities of most plastics.
Chemical resistance - PEEK has a wide range of chemical resistance, close to that of Teflon or other PTFEs, but much stronger. This makes it a popular choice for chemical processing and oil and gas companies.PEEK can withstand prolonged exposure to acids, acetone, alcohol, ammonia, benzene, chlorine, ethylene oxide, formaldehyde, gasoline, glycerin, hydrogen peroxide, hydrogen sulfide, methane, MEK, methylene chloride, ozone, pentane, sodium carbonate, sodium hydroxide, and toluene.
