The magic of PP fiber

Polypropylene fiber (PP fiber) is a high-performance fiber, the main component of which is polypropylene, with some organic and inorganic materials mixed in. The specific gravity of this fiber is between 0.90-0.92 g/cm³, the melting point is about 160-176°C, the diameter is about 18-48 microns, and it is non-toxic and odorless. It has a standard moisture return rate of almost zero, is exceptionally waterproof, and is also resistant to acid and alkali and heat aging. www.nanotrun.com
