China said polypropylene, isotactic polypropylene as raw material obtained by spinning polyethylene fiber polyester synthetic fiber, chemical fiber lightest varieties; strength of 35 ~ 62cN / dtex; wear resistance second only polyamide fibers; Polypropylene good corrosion resistance specification, especially inorganic acids proved: Compared with ordinary mortar / concrete, such as adding volume content of 0.1 percent (about 0.9Kg / m3) monofilament fiber, crack resistance mortar / concrete improvement 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 improve the impact resistance and abrasion resistance of concrete bitumen membrane English: bituminous waterproof sheet: Polypropylene specifications, Shouguang Tianxiang waterproof (certified), polypropylene supplied by Shouguang City Tianxiang waterproof material plant. Shouguang City Tianxiang waterproof material plant (www.txfscl.com) Shandong Weifang, waterproof, moisture-proof material leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
