Polymer withstands high temperatures

Victrex WG polymer withstands mechanical stresses of high-heat environments where metals previously failed. The polymer reduces frictional losses, for instance, leading to a reduction in the power consumption of pumps. This, in turn, reduces stress on components and increases life. The PEEK-based polymer also eliminates the possibility of corrosion.

Additional features of the polymer include good hydrolysis and chemical resistance, up to 70% weight reduction compared to metals, good dimensional stability at 150°C (302°F), a coefficient of thermal expansion similar to steel, high abrasion resistance for loads at 4,500 rpm, low coefficient of friction, and the possibility of redesigns to achieve part miniaturization that reach tight tolerances during the injection-molding process.
