Polypropylene high strength filament has a long history of development, but now it has been widely used, which is also because polypropylene high strength filament has outstanding characteristics.

The outstanding characteristics of polypropylene high strength filament:

1.It has a relatively high tensile strength, up to 70.6cN/tex (8g/d), which is almost twice that of ordinary polypropylene fibers.

2.The density of polypropylene high-strength filament is the smaller among synthetic fibers, at 0.91, which is lighter than water.

3.The thermal conductivity is 0.1~0.3J/m · s · K, which is such a low value, so the insulation performance is very good.

4.There is almost no moisture absorption, making it difficult to dye, but color masterbatch solution can be used for coloring. The moisture absorption rate is zero, so the wet strength is equal to the dry strength, and the strength of the product in water will not decrease.

5.Compared with various fibers in terms of resistance, acid resistance, and alkali resistance, polypropylene fibers have excellent chemical resistance. Apart from being inferior to polytetrafluoroethylene fibers, polypropylene fibers are superior to polyester, nylon, acrylic, and vinylon.
