New energy vehicle connectors mainly use modified PPS, PBT, PA66, PA

 

Motor drive system and cooling system

 

1. The IGBT module

 

IGBT module is the core component of electronic control system and DC charging pile of new energy vehicles, which determines the energy utilization rate of the vehicle. In addition to the traditional metal and ceramic materials, PPS engineering plastics are gradually applied.

 

2. Car water pump

 

Electronic pump rotor, pump shell, impeller, water valve and other requirements of high toughness, high wear resistance, high strength, the main use of modified PPS material.
