What is polypropylene fiber?

Polypropylene fiber is a new type of concrete reinforcement fiber, known as the secondary reinforcement of concrete. The flame-retardant modification of polypropylene fiber is mainly prepared by adding modification and flame-retardant finishing. Polypropylene fiber is a kind of high-strength polypropylene bunched monofilament fiber, through special surface treatment technology, to ensure that the fiber in concrete has excellent dispersion and cement body holding force. Polypropylene mainly through the use of halogen flame retardants and antimony trioxide synergies to obtain flame retardant effect, usually first add high concentration of flame retardants and other additives in polypropylene slices, through blending to make flame retardant masterbatch, and then with conventional polypropylene slicing fiber melt spinning forming, the preparation of flame retardant polypropylene fiber. The phosphor-Bromine co-acting flame retardant system used for polypropylene fiber has good flame retardant effect and little environmental pollution, while the phosphor-nitrogen co-acting flame retardant system used for polypropylene fiber has better flame retardant effect, but the application conditions in polypropylene fiber are relatively high.

Shandong Huimin Taili Chemical Fiber Products Co., Ltd. was founded in 2017, the company now has the domestic advanced fiber production line, twisting production line. Anti-aging, acid and alkali resistance, low boiling water shrinkage, high breaking strength, low elongation, environmental protection and pollution-free. Widely used in chemical fiber rope net, fire hose, sling, safety belt, concrete, mortar, engineering fiber, etc., is to replace polyester, nylon, ethylene fiber, nylon, glass fiber new ideal material.
