The results of scratch resistance test show that Risheng scratch-resistant PP is superior to traditional interior PP material in scratch resistance.

Excellent comprehensive performance

 

PP is more and more used in automobile parts because of its low density, high cost performance and excellent comprehensive performance. However, due to the poor scratch resistance of the surface of PP material, the aesthetic degree of the product is greatly affected, which restricts the application in the automotive interior.
Through the all-round design and research and development of the material system, Shanghai Rizhisheng has broken through the technical bottlenecks of PP in terms of scratch resistance, multi-axial impact, aging resistance, etc. for a long time, and has developed scratch-resistant PP materials for automobile interior trim that can meet the standards of various main engine factories.
