EcoPaXX® in automotive

EcoPaXX combines excellent thermal and mechanical properties with low moisture uptake, high chemical resistance and good surface finish.

Explore EcoPaXX® in automotive

EcoPaXX combines excellent thermal and mechanical properties with low moisture uptake and high chemical resistance. This makes it especially suitable for automotive applications that require good mechanial performance after conditioning, water/glycol ageing and road salt exposure. Additionally, EcoPaXX has excellent surface aesthetics, which is ideal for decorative components that require thermal and mechanical stability, such as engine covers.

Featured applications

Coolant expansion tank

Automotive |

30% Weight reduction vs PA66;50% cooling time reduction vs PA66;up to 60% carbon footprint reduction;Excellent retention of properties in water/glycol of 135°C;Drop-in solution for PA66-GF tooling if PA66 fails to meet requirements

Crankshaft Covers

Automotive | Drivetrain Transmission

ForTii® PA4T, Stanyl® PA46 and EcoPaXX® PA410 allow for light weight solutions (50% less weight compared to metal) and for cost effective solutions (up to 25% lower system/part costs compared to metal); ForTii® PA4T, Stanyl® PA46 and EcoPaXX® PA410 allow for reliable solutions due to good compatibility with FKM/LSR rubbers and to good creep&fatigue resistance in case of Stanyl® and to good temperature resistance up to 150-200°C in case of ForTii® and EcoPaXX®; Xytron™PPS can provide lots of benefits on creep, fatigue&oil resistance, even at elevated temperature.

EcoPaXX® PA410 allows for reliable solutions to its high temperature resistance (better than PA6), its great surface appearanceand low warpage level; EcoPaXX® PA410 allows for more sustainable solutions due to its excellent carbon footprint (70% biobased) as compared to PA6 and PA66

A natural performer

EcoPaXX is DSM’s most established biobased engineering plastic. It combines DSM’s propriety C4 technology with the power of nature’s C10 building block derived from castor plants, which do not compete with the food chain. The combination of the short C4 block and the long C10 block gives EcoPaXX high mechanical properties of typical short chain polyamides, but combines these with lower moisture update and higher chemical resistance more typical of long chain polyamides. EcoPaXX can easily be processed in PA66 tools while resulting in better surface quality. This makes it an ideal candidate for when performance, aesthetics and sustainability come together.
