What is a peek ring?

Injection-Molded Polyetheretherketone (PEEK) is a high-modulus material with an excellent tolerance for high temperatures. … Extruded Polyetheretherketone (PEEK) is typically used as anti-extrusion or backup-ring material because of its relatively low elongation and high stiffness. Material is FDA approved.

Likewise, is Peek an elastomer?

PEEK is a high temperature, semi-rigid elastomer offering a combination of chemical, mechanical and thermal properties. PEEK is excellent for water and steam applications at high temperatures and pressures to 6000 PSI (400 BAR) while providing good corrosion resistance.

One may also ask, what is PEEK valve? PEEK is the common name for Poly Ether Ether Ketone. … Flow-Tek offers PEEK in two grades, unfilled and filled. The filled is a unique blend of carbon/graphite fillers to ensure consistent, uniform material properties. This lowers the coefficient of friction, reducing the operating torque requirements of our valves.

Similarly, why is PEEK so expensive?

High performance polymers are becoming available for specific applications. PEEK competes with certain Aluminium alloys but is half the weight of Aluminium. … For aerospace application this sounds very promising!

Is Peek a word?

The first one we learn is peek: it has to do with looking, especially furtively or quickly or through a small space, as in “open the box and peek inside.” It’s both a noun and a verb; when you peek, you take a peek. … It comes from a French word meaning literally “to prick,” but its earliest English use was as a noun.

Why is PEEK so strong?

PEEK can tolerate mechanical and physical stress, and also has excellent chemical resistance and high heat tolerance, which together provide this material with advantages over metal parts. These qualities make PEEK suitable for the automotive, aerospace, and other general industrial settings.
