Stanyl® TW241B3, PA46-CF15 - Envalior

Stanyl® TW241B3

15% Carbon 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® TW241B3 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. TW241B3 has an excellent track-record in gear applications.
