Polypropylene (PP) Geotextiles

Polypropylene (PP) Geotextiles is a 100% polypropylene staple fibers needle formed, and its irregular weave mesh random to form a high strength fabric and the size of a balanced and stable. Polypropylene fiber manufactured according to special formula to resist ultraviolet rays. Encountered in the soil of ordinary non-active chemicals. Such fibers do not corrode or mildew, biologically non-degradable and resistant to insect or rodent damage. Polypropylene pH values 2-13 within the framework of the stability of。In addition, it lists the physical fit for the next performance parameters.
