Engineering Materials

Ensuring a smooth driving experience

As car manufacturers focus on reducing carbon emissions, they are also seeking to create the best driving experience possible. The suspension system is essential to ensuring a smooth and enjoyable ride – with reduced noise, vibration and harshness for the driver and passengers.

Our broad portfolio of materials has grades specifically designed to reduced noise, vibration and harshness in suspension parts, while delivering the strength and stiffness required for a reliable solution. Add up to 50% weight reduction over conventional metals, and substantial cost savings on the processing side, and our materials have proven themselves as the materials of choice for metal replacement in suspension systems.

Learn about vehicle air springs material challenges

A vehicle’s suspension system directly influences vehicle safety, control, and comfort. Air spring technology will be used on more vehicle suspension systems to provide improved dynamic ride characteristics and optimum height adjustments, along with better driving comfort and safety, especially with higher loads. Plus, suspension systems also provide improved driving efficiency and CO2 footprint reduction across the entire value chain and a reduced total cost and weight.

In the past, air spring manufacturers relied on metal and rubber as primary air spring components, including Polyamide 6 (PA6), Polyamide 66 (PA66), but unfortunately, as with many materials, you can expect to experience supply chain challenges with PA66. The raw materials used to make these materials is dominated by a few global suppliers, which limits supply and increases costs. In addition to supply chain challenges, many of the materials used for air springs are associated with higher costs, inefficiencies, and limited performance and design flexibility.

Deliver sustainable and readily available advanced materials for vehicle air springs

To overcome all these challenges, DSM engineering Materials provides Akulon® PA66, Akulon® PA6 and Arnitel® TPC for air spring components, helping you meet performance, sustainability and lightweighting requirements.

These advanced material solutions provide:

  • Excellent thermal performance across a broad temperature range
  • High strength and chemical resistant chemistry
  • Easy processing and weldability
  • Up to 50% lower carbon footprints from bio-based and recycled materials
  • Availability outside of traditional supply chain

Akulon® PA6 and Akulon® P66 outperform aluminum in a variety of factors for air suspension components, including processability, application weight, chemical resistance, surface roughness after molding/casting, weldability and total cost.

The unique chemistry of Arnitel® TPC makes it an attractive option because it provides strong, flexible material solutions for boots and bellows within suspension systems. For other components within the system, DSM offers Akulon®, a material solution with hard and soft segments that deliver flexibility, high-temperature resistance, strength and excellent processing characteristics. These features make Akulon® PA66 and Akulon® PA6 ideal for suspension components, including pistons, piston pots, contour shells, winding rings and caps, and gaiter pots.
