Issue 11/2018 - Metal substitutes for automotive high-temperature, low-wear plastic gears

A few days ago, DSM said that the company's Stanyl^®PA46 high-temperature, low-wear plastic gear has been used in actuators in
more than 200 million vehicles around the world.
After use, the cost can be saved by more than 40%; The density of Stanyl PA46 is only 1/7 of steel, and the weight of a complete set of gear sets made of Stanyl^®®PA46 is only 40%~60% of metal gear sets; It is also quieter and less carbon-emitting, and for a mid-size car, using the Stanyl^®PA46 instead of metal to make gears can reduce carbon emissions by 0.
06 grams
per kilometer.

In addition, Stanyl^®PA46 offers excellent wear and tear performance, especially at high temperatures and dry friction, reducing wear by up to 50% compared to high-performance materials such as PPA, PEEK, PA66, etc.
, thus greatly improving the durability
of gears.
When used in gears for motor management actuators, the service life of the gears can be extended to three times
that of the standard (40 million load cycles).
