Polyetheretherketone Seals - PEEK Polymer Sealing

Polyetheretherketone (PEEK) Sealing

Polyetheretherketone (PEEK), an organic thermoplastic polymer, has excellent mechanical and chemical resistance properties that are maintained at high temperatures. PEEK seals can be heated, cooled, and heated again without degradation since they are composed of thermoplastic materials.

Duron® PEEK Polyetheretherketone

Material NameMaterial DescriptionOperating Temperature Range (°F)Wear Resistance (1=Poor & 5=Excellent)Mating Metal Wear
DURON® 19 Injection-Molded Polyetheretherketone (PEEK) is a high-modulus material with an excellent tolerance for high temperatures. Highly recommended for backup rings. Color is tan. -200 to 480 4 Medium
DURON® 50 Polyetheretherketone (PEEK) a high-perfomance engineered thermoplastic material, is used where a high modulus polymer is required to resist high pressure or loads. Material is FDA approved. Color is grey. -350 to 250 4 Medium
DURON® 62 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. Color is tan. -350 to 250 4 Medium
DURON® 150 Bearing-Grade Polyetheretherketone (PEEK) is a premium material for bearing applications where traditional metal ball bearings cannot be used. Duron® 150 has a very high temperature tolerance. Color is black. -350 to 250 5 Medium
