Stanyl® for wear & friction
For many years Stanyl® is the material of choice in timing chains or chain guides in engines, bearing cages or for gear trains. The high stiffness resulting from the high degree of crystallinity provide a very good resistance to wear and good friction performance especially at high temperatures. At lower temperatures the strength of the material is especially shown at high torque levels, where normally metal gears are being applied.
Explore Stanyl® for wear & friction
Many different materials are being used in the wear and friction arena, and Stanyl is a common material in that list. For a polyamide the friction performance at high temperatures are unmatched, and for the lower temperatures, focusing on Gears the material opens up an arena that is typically dominated by metals. In the portfolio the division can be into grades specifically designed for timing chains, but also for gear trains a complete portfolio can be positioned. Glass-filled, carbon-filled or unfilled materials are available and also modified version for use of non-lubricated friction.
Sustaining high performance
Stanyl is the only aliphatic polyamide that is capable of working in the field of the high-temperature polyamides, and with that it also takes the largest volume space in that area of all polymers. When focusing on the details, the core strength stems from two key properties being the high crystallization rate, which leads to small crystals, and additionally the high degree of crystallinity. These two properties create three key strengths in Stanyl, being the excellent mechanical performance at high temperatures, excellent wear and friction properties and superior flow.

An introduction to gears and actuators
Gears can be found everywhere: from cars to kitchen appliances and clocks. Traditionally, gears in demanding applications are made from metal, but there is an increasing demand for plastic gears. In this video, Martin Wolffs, product manager at Envalior, explains why the tooth temperature of a gear is a key property for choosing the right gear material.
