Polyetheretherketone (PEEK)/Applications

PEEK (Polyetheretherketone) is one of the industry’s most chemically resistant plastics and offers excellent strength, superior fatigue resistance, and a continuous-use temperature of 300°C.

Applications include:

• Aerospace
• Automotive
• Electrical/Electronics
• Energy
• Industrial
• Medical
• Oil & Gas
• Semiconductor

Metal Replacement

PEEK's strength and toughness (tensile strength from 14K to 16K; Izod Impact Notched from 2.1 to 5) at light weights coupled with thermal and dimensional stability make it a prime candidate for replacement of metals and other composites. The polymer is inherently flame retardant (a property that increases in grades containing fillers), completely non-corrosive and non-conductive, and maintains superior long term dimensional integrity.

Transmissions

Carbon fiber filled and graphite (PTFE) filled PEEK have magnificent wear properties and extremely low coefficients of friction. Combining that with high heat (CUT 300 C) and chemical resistance and retention of dimensions over time gives long life to PEEK components in "under-the-hood" automotive and industrial transmissions.

Medical Devices

PEEK can be sterilized using all conventional sterilization methods, including steam, ethylene oxide, vaporized hydrogen peroxide and gamma radiation. It also has a high degree of purity in its unfilled grades. FDA approved material.

Automotive

With maximum heat deflection temperatures (HDT) ranging up to 315°C and continuous use temperatures to 300°C PEEK is an excellent option for "under the hood" automotive applications.

Tribology is critical in engine components. Carbon filled PEEK provides exceptional friction and wear properties over a wide range of temperatures.

Aerospace

PEEK's strength and toughness (tensile strength from 14K to 16K; Izod Impact Notched from 2.1 to 5) at light weights coupled with thermal and dimensional stability make it a prime candidate for replacement of metals and other composites for aerospace.

The polymer is inherently flame retardant (a property that increases in grades containing fillers), completely non-corrosive and non-conductive, and maintains superior long term dimensional integrity.

Oil & Gas

The oil & gas industry consumes nearly 50% or PEEK usage worldwide, driven by the twin demands of heat (to 260°C) and pressure (to 30K psi) in down hole applications.

Matched with abrasion resistance superior to steel, chemical resistance that's immune to seawater and hydrocarbons, remarkable tensile and compressive strength, and minimal creep for unparalledl performance.

Gears & Sprockets

Gears in high temperature, dry or lubricated environments, such as on business machines can benefit from Torlon's dimensional and thermal stability, wear resistance and strength.
