In demanding industrial environments involving high temperatures, high pressure, corrosive chemicals, and abrasive particles, conventional sealing materials often fail due to creep deformation, hydrolysis cracking, excessive wear, and dimensional instability. Even reinforced materials with fillers frequently struggle to prevent damage to mating surfaces or maintain long-term reliability.
Repeated shutdowns, maintenance cycles, and spare part replacements can lead to substantial operational losses and reduced production efficiency. For industries where reliability is critical, choosing the right sealing material is no longer optional - it is essential.
ARKPEEK is specifically engineered for harsh operating conditions. With outstanding creep resistance, hydrolysis resistance, chemical stability, and wear performance, ARKPEEK maintains dimensional integrity even in environments exceeding 200°C.
Compared with traditional polymers, ARKPEEK delivers:
High mechanical strength
Excellent dimensional stability
Low thermal expansion
Long service life
Lightweight performance
Reduced maintenance costs
These advantages make ARKPEEK an ideal material for high-end industrial sealing systems.
Rotary seals operate under high-speed shaft rotation, generating frictional heat, centrifugal force, and fluid pressure.
Wear resistance
Low friction coefficient
Thermal expansion stability
Protection of mating surfaces
Modified ARKPEEK compounds provide excellent self-lubrication and low wear characteristics, helping reduce friction while protecting shafts and metal counterparts from damage.
Piston rods and plungers create continuous reciprocating motion, exposing seals to cyclic pressure and sliding friction.
Anti-extrusion performance
Creep resistance
Chemical resistance
Dimensional stability
ARKPEEK offers exceptional creep resistance and structural rigidity under pressure, ensuring long-term sealing reliability in dynamic systems.
Static seals are used in flanges, end caps, and fixed joints exposed to long-term temperature and pressure loading.
Compression set resistance
Aging resistance
Chemical stability
With low moisture absorption and superior chemical resistance, ARKPEEK maintains sealing integrity even during long-term exposure to aggressive media.
ARKPEEK can operate continuously at temperatures up to 260°C, with short-term exposure capability reaching 300°C. It maintains dimensional stability even under high-pressure environments.
Compared with softer engineering plastics, ARKPEEK provides higher rigidity and reduced thermal expansion, helping maintain controlled sealing clearances under thermal cycling.
