• TPU material with low free PPDI + polycarbonate system can produce better phase separation and stronger chain segment structure through optimized design, so as to provide excellent high temperature resistance, dynamic fatigue resistance and low compression set, In particular, it can maintain high sealing force at high temperature (130 ℃). 

• optimize the product structure through finite element analysis, break through the limitations of the mainstream structure in the existing market, and improve the service life of the oil seal; and carry out test verification based on the test bench to ensure the effectiveness and reliability of the product.
