Polypropylene fiber is the synthetic fiber with the best resistance to humidity. It can stand the temperature of 90℃ and it has the resistance to many of the acid alkali. When it is keep in damp conditions, it only absorbs 0.6% of the air and the property of the fiber keeps no change. Polypropylene is a kind of good thermoplastic material. The polypropylene felt is normally used to make the low-temperature pulse filtration bag for smelting plant, and the pulse filtration bag for chemical and pharmaceutical factory. Polypropylene is especially suitable for wet conditions, but the temperature must be kept low.
