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® TW271B6 is a friction-modified 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. TW271B6 has an excellent track-record in gear applications.

Applications

Coolant valve actuators

Industry
Automotive
Material
  • •} Higher torque and durability performance than PPA and PA66
  • •} Allows more compact actuator design and weight savings
  • •} Comparable performance to specialized materials without the need for expensive additives (e.g., carbon fiber or wear & friction optimizers) creates opportunities for cost savings

CRB Cap

Industry
Automotive
Material
CRB Cap is a press fitted cap on the clutch release bearing. The cap comes in contact with the diaphragm spring of the clutch when the clutch is pressed for disengaging the transmission with the engine. This cap isolates metal to metal contact of CRB flange and diaphragm spring fingers.}

CRB Housing

Industry
Automotive
Material
The component is a plastic housing, enclosing the clutch release bearing (CRB). The housing slides over the sleeve and the clutch pedal operates the fork shaft which moves the CRB housing. The housing also encloses grease that serves as lubrication of the CRB.}
