Among the many synthetic fiber industrial yarns, the high strength and impact resistance of polypropylene high strength yarns, as well as their flexibility and chemical resistance make them extremely competitive. In addition, its low investment in production equipment, raw materials, cheap, least energy consumption, less environmental pollution, with obvious technical and economic advantages.

High-strength polypropylene fiber performance:

1. High strength polypropylene fiber can be comparable with polyester, nylon industrial yarn, and strong in the wet and dry conditions are exactly the same

2. The density of polypropylene is 0.919 / cm ', which is the lowest density in all industrialized synthetic fibers. Its density is only equivalent to 66% of polyester (1.389 / cma) and 80% of nylon (1.149 / cm3) . From the price and density of the wire to consider the use of polypropylene high-strength wire as raw material, the cost will be much lower than polyester or nylon industrial yarn. In addition, due to small moisture absorption of polypropylene (MO.1%), especially suitable for marine products and other non-hygroscopic products.

3 wear resistance and good flexibility

4. Mildew resistant. Polypropylene from insects, bacteria erosion.

5. The stability of chemicals is good. Due to the absence of active groups in the molecular structure of polypropylene, its stability to acids, bases and other chemicals is very good, even better than polyester and nylon, making it suitable for many chemical applications.

6. UV and staining have been resolved. Polypropylene itself lightfastness is not good, but through the use of stabilizers added polypropylene chips can achieve excellent resistance to UV radiation degradation, the product is suitable for outdoor use. Polypropylene dyeing is difficult, but has been solved by adding dyestuffs or stock solutions.

Compared with Europe and the United States, Southeast Asia, polypropylene production and demand vary greatly in size, taking into account future needs, it can be said that the future development of polypropylene mainly in Asia, especially in Southeast Asia, polypropylene market will rapidly expand, and its trends will affect The world polypropylene industry development. Our country should seize the opportunity to vigorously develop the polypropylene industry, occupy a favorable position as soon as possible.
