Macro Structural Polypropylene Fibers have good dispersion and the adhesion of the cement matrix. Because of special shape easy to construct and has no damage to the equipment.To protect steel from corrosion.
Macro Structural Polypropylene Fibers
Macro Polypropylene fibers ,also known as plastic steel fiber,is refined from polypropylene as the main raw material through a special production process.The surface of polypropylene crude fiber is rough and uneven.It is a new type of reinforced and toughening material.The product not only has the function of steel fiber,but also has the advantages of synthetic fiber.It can replace steel fiber for the crack resistance enhancement of cement concrete. It not only maintains the original concrete fiber,but also greatly improves the ease and dispersion of the fiber in concret. It has high strength corrosion resistance,high temperature resistance, strong chemical stability, strong gripping force with concrete, and easy construction without damage to equipment.
