Introduction of Good Polypropylene Fiber

Good polypropylene fiber is a new type of concrete reinforcing 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.

The flame retardant modification of best polypropylene fiber is mainly prepared by adding modification and flame retardant finishing.
Polypropylene mainly obtains the flame retardant effect by using halogen flame retardants and synergists such as antimony trioxide to obtain flame retardant effects. Usually, high concentrations of flame retardants and other auxiliaries are added to the polypropylene chips first, and the flame retardant is produced by blending. The masterbatch is then melt-spun with conventional polypropylene chips to form flame-retardant polypropylene fibers. Phosphorus-bromine synergistic flame retardant system used in polypropylene fiber has good flame retardant effect and less environmental pollution, while phosphorus-nitrogen synergistic flame retardant system used in polypropylene fiber has better flame retardant effect, but The application conditions in polypropylene fibers are relatively high.
