Crankshaft Balance Gears

産業
Automotive
  • Stanyl® PA46 allows for 40% lightweight (additional CO₂ reduction through improved moments of inertia) and 35% more cost effective solutions versus metal and it provides a significant reduction in rattling noise of gears in comparison with metal gears
  • Stanyl® PA46 is more cost effective in comparison with PEEK

EPS gears

産業
Automotive
  • Stanyl® PA46 allows for lightweight and cost effective solutions as compared to machined cast metal and also offers advantages in NVH
  • Stanyl® PA46 allows for reliable solutions due to its superiority in fatigue performance as compared to PA66
  • Stanyl® PA46 allows for cost effective solutions due to its faster cycle times in comparison with PA66 and PPA

EPS Steering components: Gears, Flex couplers and Sensors

産業
Automotive
  • Stanyl® PA46 allows for light weight solutions (17% less weight than a metal alternative) and for sustainable solutions (NVH significant lower compared to metal)
  • Stanyl PA46 allows for reliable solutions due to its low friction and high abrasion resistance performance

Oil Pump Gears (2-wheelers)

産業
Transportation
  • Stanyl® PA46 allows for light weight solutions versus metal
  • Stanyl® PA46 allows for reliable solutions due to its better mechanical properties at elevated temperatures in comparison with PA66 and PPA and due to its much better abrasion resistance and lower friction at elevated temperatures in comparison with PA66 and PPA

Oil Pump Gears (automotive)

産業
Automotive
  • Stanyl® PA46 allows for light weight solutions versus metal and it enables compact designs and reduced noise (as much as 20% reduction versus other plastics)
  • Stanyl® PA46 allows for reliable solutions due to its high abrasion resistance (PA46 yields reduced wear (backlash) after 500 hours, and Stanyl® TW241B3 showed 5 microns wear versus 20 microns for PA66) and it yields high safety factors under jamming condition
