Stanyl® TW241F6

30% Glass Reinforced, Heat Stabilized, Lubricated

General 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.
Product
Stanyl® TW241F6 is a high heat polyamide that offers excellent creep resistance, strength, stiffness and fatigue resistance especially at high temperatures in combination with cycle-time advantages and excellent flow.
