ANTIFUNGAL POLYPROPYLENE RESIN COMPOSITION WITH EXCELLENT SOUND ABSORBENCY

摘要

Provided is a polypropylene resin composition, which shows excellent noise-absorbing property and anti-bacterial property derived from the use of an antibacterial agent, and maintains excellent impact resistance and heat resistance, and is useful for the production of pipes. The polypropylene resin composition having excellent noise-absorbing property and anti-bacterial property comprises: (A) 40-60 parts by weight of a polypropylene resin; (B) 40-60 parts by weight of a mixture of talc with barium sulfonate; and (C) 1-20 parts by weight of a nanosilver resin that is a polymer resin master batch having a silver nanoparticle content of at more than 0.1%. In the polypropylene resin composition, the mixture of talc with barium sulfonate comprises talc and barium sulfonate in a mixing ratio of 1:9 to 9:1.
