Introductions-synthetic polymer modified pp fiber for reinforced concrete
Raw material of polypropylene fiber is 100% pure polypropylene added special additives, with ability to resist the acid, alkali and salt . polypropylene fiber makes the fiber not lump and uniform distribution in the concrete mortar , polypropylene fiber is ultraviolet resistance to ensure it in the concrete, thermal insulation mortar working for a long time.
Polypropylene fiber has stable chemical properties, not absorb other material and produce chemical reaction with other components. Polypropylene fiber good at changing physical properties of concrete and mortar, good compatibility with cement-base material and other admixture.
Double anti-cracking ability if added polypropylene fiber in cement-base material. Can completely prevent cracks under the condition of reasonable proportion and proper construction.
Adding polypropylene fiber can greatly improve the concrete or mortar crack resistance and impact resistance, abrasion resistance, freeze resistance, reduce plastic settlement and cracking.
