Applications

Air inlet manifolds

Industry
Automotive
  • <ul> <li>Akulon® PA6 allows for light weight (40% lighter) and cost effective solutons as compared to metal</li> <li>Akulon® PA6 allows for reliable solutions due to its higher heat ageing resistance and its better welding strength in comparison with PA66</li> <li>Akulon® Ultraflow grades allow for addtional cost effectiveness due to 25% cycle time advantage as compared to standard grades</li> </ul>

Charge Air Cooler Caps

Industry
Automotive
  • <ul> <li>Stanyl® PA46 allows for light weight solutions (40-50% lighter) and more cost effective solutions than metal</li> <li>Stanyl® PA46 allows for reliable solutions due to its better creep/fatigue resistance than PPS and PPA and in case of Stanyl® Diablo due to its excellent long term temperature resistance up to 230°C</li> <li>Akulon® and EcoPaXX® allow for light weight solutions (40-50% lighter) and more cost effective solutions than metal at the cold side.</li> <li>Xytron™ PPS allows for super high temperatrue resistance for long term.</li> </ul>
