GB 18173.1-2006 "waterproofing the first portion of the sheet" proved: Compared with ordinary mortar / concrete, such as adding volume content of 0.1 percent (about 0.9Kg / m3) polypropylene monofilament polyester fiber, mortar / concrete crack resistance increased by 70%. 2, greatly improving the impermeability of concrete. Polypropylene monofilament fiber bundle concrete 0.9Kg / m3 content than ordinary concrete impermeability capacity increased by 60% to 70%. 3, significantly improving impact resistance and abrasion resistance of concrete propylene primarily through the use of halogenated flame retardants and antimony trioxide synergist interaction to obtain flame retardant polypropylene specifications, usually the first to add a high concentration in polypropylene sections flame retardants and other additives, flame retardant masterbatch after blending manufacture, then sliced ??with conventional polypropylene fibers melt spinning polypropylene Specifications | Shouguang Tianxiang waterproof (certified) | Huangdao polypropylene by the Shouguang City Tianxiang waterproof material plant provided.
