2007-07-03 News Release
Arnitel is ideally suited for automotive applications The use of Arnitel PB 582-H to replace rubber for automotive parts has demonstrated cost savings for production and processing as well as weight reduction.
Arnitel* PB 582-H, a Copolyester Elastomer from DSM Engineering Plastics, replaced rubber in a recent clean air duct automotive application. The move yielded a weight reduction of 50% and cycle time reduction of 50% compared to rubber, which resulted in 0.6 Euro/part processing saving and a 0.8 Euro/part fuel saving (a total annual saving of 70.000 Euro for 50.000 parts). Many automotive applications are currently designed in high end rubbers. Typically these applications are a combination of metal and rubber, making them expensive to produce. Every application has to be designed specifically for every engine/platform combination to optimize the dynamic response and account for the load bearing requirements. This design typically involves fine-tuning the rubber formulation to every specific automotive application. Arnitel can be designed with thinner wall sections for a given flexibility than other materials. Faster cycling also reduces processing cost and total part costs can be lowered by as much as 30%. Further benefits are better acoustic damping (by up to 10%).
This material is ideally suited for these automotive applications, giving its excellent load bearing capabilities, its relatively constant mechanical behavior over the operating temperature range of automotive and its flexibility in design and mechanical properties. Significant redesign will be key to this application to fully make use of the added performance of Arnitel. High Performance Materials of DSM Engineering Plastics such as Stanyl*
and Arnitel do lead in specific cases such as gears and airducts to lower
system costs even in comparison to standard materials as PA66 or rubber.
The added value for the customer is generated by these materials in those
cases through faster production cyclesin automotive applications leading
to lower processing costs per part, lower after-treatment costs, greater
freedom of design leading to lower material and/or processing costs per
part and better part performance compared to competitive high heat resins. The use of Stanyl PA46 as alternative to metal can lead next to possibilities
for weight reduction, noise reduction and again system cost reduction.
