Stanyl® TW371

Wärmestabilisiert, verbesserte tribologische Eigenschaften

Allgemeine Information

Stanyl® is our high-performance polyamide 46 used for applications in automotive, E&E, gears and outdoor power equipments.
Stanyl® is a high performance polyamide that provides unmatched performance and value for demanding applications in which superior heat resistance, design stiffness, wear & friction and process flow qualities are required.
Because Stanyl retains its mechanical properties at high temperatures up to 220°C, this makes it ideal for extremely high-performance applications, where it outperforms PPA, PA6T, PA9T, and often PPS and LCP.

Anwendungsbeispiele

Front End Accessory Drive Parts: Belt Tensioner,Damping bands, Shoes and Bushings

Branche
Automotive
  • Stanyl® PA46 allows for reliable solutions (Extended Tensioner Life, Reduced / eliminated warranty claims) due to its unmatched dry running wear & friction performance at elevated temperatures, its damping capability (consistent Frictional Properties Minimal or no slip / stick), its superior creep Resistance at elevated temperatures
  • Stanyl® PA46 allows for new posible designs

MTF/DMF Components

Branche
Automotive
  • Stanyl® PA46 allows for lightweight solutions versus metal and cost effective solutions versus PEEK
  • Stanyl® PA46 allows for reliable solutions due to its excellent wear performance with low or high friction, best in class mechanical properties (combination with high stiffness, good fatigue and ductility at high and low temperatures) and its chemical resistance against used greases and oils

New Generation Slide Shoe Surfaces

Branche
Automotive
  • Stanyl® TW371 PA46 allows for sustainable solutions (up to 1 g/km lower CO₂ emissions) because of lower friction coefficients at elevated temperatures compared to PA66
  • Stanyl® TW371 PA46 allows for reliable solutions (7 times longer life time) due its higher abrasion resistance in comparison with PA66
  • Stanyl® PA46 allows for cost effective solutions due to faster cycle times in comparison with PA66
  • Stanyl® HGR1 produces lower frictional torque in comparison with any other material (e.g. PA66) at relatively low engine speeds ranging from idle to 1800 rpm.
  • Stanyl® HGR1 also performs well at vehicle cruise speeds
  • Stanyl® HGR1 will provide OEM's with a very cost-effective tool for reducing fuel consumption
