DSM in Automotive

Maximum safety, minimum weight in Electronic Power Steering Systems

Are you looking to reduce weight and carbon emissions in Electronic Steering Systems (EPS) without compromising driver safety? Our Arnite® XT automotive plastic will help steer you in the right direction, ideal for replacing metal in the EPS while delivering the very highest performance. 

Our solution is proven to deliver a weight reduction of up to 50% in metal-to-plastic conversion of EPS systems – and a cost reduction of between 10-40%, depending on the complexity and region of production. Which is why DSM was recognized by Frost & Sullivan in 2014 for ‘enhancing value for Tier 1 suppliers of steering systems by establishing a new benchmark in weight reduction’. In this growing area, we are leading the field.

Arnite for EPS systems

This next-generation EPS system is based on our Arnite XT - a high performance polyethylene terephthalate (PET) thermoplastic that offers extremely good dimensional stability due to its low moisture absorption and a very low and constant coefficient of linear thermal expansion (CLTE) comparable to aluminium.

Arnite XT is unique in its ability to meet extremely narrow precision requirements consistently, across multiple batches. However, unlike aluminium, Arnite XT is injection moldable – which means improved cycle time and cost reduction for manufacturers thanks to more efficient processing. 

Safe EPS systems 

Most importantly for drivers, our Arnite XT solution for EPS systems is proven to be safe – meeting stringent safety requirements covering impact, strength and torque tests, to one-time misuse tests, to high temperature exposure and long-term durability.

This is based on a Failure Mode and Effect Analysis (FMEA) system that covers safety in design, processing and the material itself across the entire value chain – from raw material to the finished part. 

For manufacturers looking to produce EPS systems that benefit people, planet and profit, our product portfolio will steer you in the right direction through 2015 and beyond…
