Excellent wear-resistance PEEK mechanical seals

PEEK, high modulus material, a high temperature resistant, high performance thermoplastic special engineering plastic. It has good mechanical properties and chemical resistance, wear resistance, hydrolysis resistance and other properties.

High temperature resistance
PEEK has a high glass transition temperature and melting point (334 ° C), which is one of the reasons why it can be reliably applied in applications requiring heat resistance. Its load thermal deformation temperature is up to 316 ºC, continuous use temperature is 260 ºC.

Mechanical properties
Peek is a plastic with both toughness and rigidity and balanced, especially its excellent fatigue resistance to alternating ability is the most outstanding of all plastics, comparable to alloy materials.

Corrosion resistance
Among ordinary chemicals, only concentrated sulfuric acid can dissolve or destroy it, and its corrosion resistance is similar to that of nickel steel.
