A bright future for automotive

Arnite® is ideal for a wide range of demanding automotive applications – from the braking system to adaptive forward lighting, to windscreen wiper housings. In both Arnite A and Arnite T formats (as well as blends and reinforced fiber-glass grades) Arnite performs in the toughest conditions. It’s strong and rigid with excellent processing characteristics and dimensional stability.

In both Arnite A and Arnite T formats (as well as blends and reinforced fiber-glass grades) Arnite performs in the toughest conditions. It’s strong and rigid with excellent processing characteristics and dimensional stability.

The automotive industry is juggling various challenges right now: The need to continue improving the safety of drivers and passengers; the drive for a reduced carbon footprint, which means improved vehicle fuel efficiency and reduction of harmful emissions; and of course the need to drive profitability – for example by reducing system costs, improving cycle time and giving engineers more flexibility.

Arnite® helps manufacturers to achieve automotive challenges. It is very easy to mold and process while being strong, rigid, with low moisture absorption and high dimensional stability. But these are only some of its qualities…

Brake booster body valves

Arnite A has been used to design brake booster body valves for some 20 years in the automotive industry. For an application where reliability is paramount to passenger safety, the material has been proven to perform faultlessly over more than one million brake cycles.

The material has exceptional dimensional stability and strength, which means you can design parts with thinner walls…which are therefore lighter. The need for post-molding operations is eliminated, while maintaining quality.

Automotive lighting

Without doubt one of the biggest challenges facing automotive lighting designers is outgassing. When designing lighting modules, the material must have minimal moisture absorption to avoid the lens fogging up; and excellent dimensional stability to enable headlamps to move freely and securely. And of course the material also needs to be heat resistant.

We’ve been tackling this key issue, first through Arnite PBT, and recently we extended our knowhow to other components, with our low outgassing Arnite PET XL material for AFL/DBL frames. In fact, it's now being used for the adaptive forward modules (smart headlights) in well-known upper segment cars.


The future

Arnite is now being used in other various automotive applications, from windscreen wiper housings to air flow mass meters, EGR/ETC covers, mirror housings, bezels and many more.

We believe this is just the beginning. The DSM team is committed to the automotive market and will continue to keep finding new ways for manufacturers to improve their vehicles using Arnite.
