Problems solved by technology

[0002] As a thermoplastic resin with excellent comprehensive properties, polypropylene (PP) has the advantages of abundant raw material sources, good mechanical properties, low density, and good chemical stability. It is widely used in the plastics and fiber industries. However, due to the flexibility of the PP molecular chain Large, high melt extrusion elasticity, polypropylene has the disadvantage of low impact strength, especially low temperature impact strength, and it is usually difficult to achieve both fluidity and mechanical properties, which limits the application of PP to a certain extent
