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.

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 DSM, explains why the tooth temperature of a gear is a key property for choosing the right gear material.

Sustaining high performance

The first commercializations of Stanyl were achieved 30 years ago. Currently, it is the largest single polymer being used in the high-performance polyamide landscape. The symmetry of the chemical structure lays the foundation of its success as it provides the basis for the high degree of crystallinity and fast crystallization speed. These two features are the basis of the three key strengths of Stanyl being excellent high-temperature mechanics, excellent wear and friction performance and superior flow. These strengths are what drives the business of Stanyl. Because of these features, this materials displays exceptional retention of mechanical properties after passing through the glass transition, giving rise to its high-temperature performance.
