TB-Polypropylene Group Fibers have such advantages as anti-corrosive and suppresses plastic deformation caused by contraction of concretes, mainly used to produce cement concrete; The polyester group fibers have such advantages as high strength, high elastic and good bond stress with the concretes, mainly used to produce asphalt concrete. Moreover, we subdivide the fineness and length specs of our Fiber to several ranks, for example, have many kinds of specs from 3mm to 60mm, which can meet the requirements of different gradation types and construction crafts.
