Drivetrain

Reducing friction and replacing metal in the drivetrain

Parts in the drivetrain have to work in very challenging conditions. In addition to exposure to high heat and corrosive chemicals, drivetrain parts need excellent wear performance since they are perpetually in motion. At the same time, manufacturers are looking to reduce weight via metal replacement, and cost on the production of drivetrain parts, including Front End Accessory Drive (FEAD) systems, elastic belts, belt tensioner bushings, and damper pulleys and elements.

Stanyl® has proven an effective replacement for aluminum in FEAD systems, in particular for the tensioner. Manufacturers are selecting this high-performance thermoplastic with increasing frequency due to its excellent wear resistance and noise reduction, as well as heat and chemical resistance in an environment exposed to dirt, rain, under-the-hood grease and oil, and high engine temperatures.

This material has also proven itself effective for Dual Mass Flywheels, which require more damping and movement of the tensioner with the potential for higher temperatures and more wear, as well as for automotive cords that withstand extreme noise, vibration and harshness. For cords, Stanyl helps manufacturers realize reductions in both weight and cost, while reducing creep compared with PA66, and providing more stretch than PET cords.

In addition to Stanyl, our portfolio includes a range of materials for other applications. For automotive pulleys, our high-flow Akulon® PA6 produces pulleys that keep their shape and last longer. With a lower injection molding temperature than PA66, Akulon® Ultraflow generates less temperature loading on the bearing being over-molded, extending the lifetime of the pulley.

Customer cases

How can we help you?

We take a scientific approach to building solutions. Our dedicated teams work closely with our customers to look at the entire process of developing new parts and components – whether it is a case of metal replacement, or developing solutions that are stronger, safer and more effective. Our methodical approach extends to every step of the process, from design and material performance to production and compliance.

  • Wear & Friction

    As car manufacturers seek to meet more strict legislation on tailgate emissions, a key area of focus is the reduction of wear and friction in the engine and transmission.

  • Flame retardancy

    As the electronics industry moved to capture more computing power into smaller spaces, it puts bigger demands on the materials used to manufacture the various parts.

  • Downsizing & Miniaturization

    As our economy places more focus on efficiency, industry is responding by creating products that are thinner, lighter, and smaller – with the same or more functionality.

  • Cost reduction & simplification

    Plastics offer a solution that is lighter in weight than metal and rubber. In addition, plastics enable the production of parts with complex geometries, meaning its possible to convert a number of components into a single, simplified part.
