Why does the car sound insulation material choose polypropylene staple fiber?

First, let's look at the characteristics of polypropylene staple fiber:

1. Polypropylene staple fiber has excellent moisture conductivity, flexibility, mesh combing and excellent thermal adhesion.

2. Polypropylene short fiber has high strength, strong crimp elasticity, light weight, low melting point, good surface permeability, acid and alkali resistance and wear resistance than other fibers;


The legislative work of using polypropylene staple fiber to produce acoustic insulation materials for vehicles, and the formulation of more and more effective noise reduction detection method standards and product regulations have always been the research topic of the development of the automotive field. At present, the conventional measures to reduce the noise of automobiles include measuring the noise of automobiles and engines in anechoic chambers, and the design of air mufflers is to improve the combustion system, reduce the roughness of fuel injection and combustion, and improve the stiffness of structural parts such as cylinder blocks, especially body sheet metal parts. Soundproof material is sprayed on a large area of plates near the noise source, engine soundproof cover is installed, tire pattern design is improved, and soundproof material is installed inside the car.
