Engineering fiber

Polypropylene fiberApplication- it is widely used in road, protection railings, bridge constructions, building of water diversion facilities in hydroelectric project, of flank wall and floor of basements and civil architecture. It has sound effect of anti-crack & anti-leakage when mixed in concrete and mortar. Features- Polypropylene fiber is high-performance fiber which is widely used in concrete and mortar project, because it can effectively control the micro crack in result of plastic shrinkage, air shrinkage, temperature variation, and prevent the crack from widening. It can prolong the life of concrete by improving its nature of resistance to erosion and abrasion.
