Stanyl®

Wear resistance

Stanyl has excellent wear and abrasion resistance and outperforms most other thermoplastics under most conditions - but especially at higher temperatures and high torque/loads.

Stanyl outperforms its competitors thanks to its higher PV rating, which enables it to perform at higher pressures and velocities.

Many materials fail under demanding application conditions, from high temperature, high loads, high velocities, harsh chemical environment and vibrations due to melting; to (POM, PA6), brittlemess (PPS, PPAs), low stiffness at high temperatures (POM, PPS, PA6, PA66, PPAs) or high abrasiveness (PPS).

However, Stanyl delivers smooth and reliable performance (see graphs below).

Modified Stanyl grades with even better wear properties are available in unreinforced as well as glass-fiber reinforced formats: The smooth and tough surface, combined with its stiffness at elevated temperatures, high melting point, high fatigue and vibration resistance, high resistance against crack propagation and resistance against oil and greases, make Stanyl an ideal material for sliding parts like valve lifter guides, chain tensioners (see graphs below), gears, bushings and thrust washers.
