Polypropylene

Polypropylene fiber can significantly improve the bond performance between fiber and cement mortar, concrete. This prevents early cracking of cement and concrete, effectively prevent the happening and development of mortar and concrete cracks, so to ensure uniform exudation, prevent segregation and hinder the formation of settlement cracks.The experiments show that mixing 0.1% volume content of fiber,the crack resistance of concrete mortarwill increase 70%,on the other side,it also can significantly improve the permeability resistance up to 70%. Polypropylene fiber (short-cut strands of very fine denier monofilament) is added to the concrete during batching. Thousands of individualfibers are then evenly dispersed throughout the concrete during the mixing process creating a matrix-like structure. ADVANTAGES & BENEFITS Reduced plastic shrinkage cracking Reduced explosive spalling in fire Alternative to crack control mesh Improved freeze/thaw resistance Reduced water & chemical permeability Reduced bleeding Reduced plastic settlement cracking Increased impact resistance Increased abrasion properties PRODUCTS SPECIFICATION Material - 100%Polypropylene Fiber Type - Monofilament Density - 0.91g/cm³ Equivalent Diameter - 18-40um 3/6/9/12/18mm Length - (can be customized) Tensile Strength - ≥450MPa Modulus of elasticity - ≥3500MPa Melting Point - 160-175℃ Crack Elongation - 20+/-5% Acid /alkali Resistance - High Water Absorption - Nil APPLICATIONS ◆ Less expensive than conventional steel mesh reinforcement. ◆ Most small builder, cash sales and DIY applications. ◆ Internal floor-slabs (retail stores, warehouses, etc.) ◆ External slabs (driveways, yards, etc.)
