MasterFiber™ F70
MasterFiber F70, a microsynthetic fiber, is a fibrillated polypropylene fiber manufactured from 100% virgin homopolymer polypropylene resins. MasterFiber F70 meets the requirements of ASTM C 1116/C 1116M, Section 4.1.3, Type III, and Note 2 and the requirements of ICC-ES AC32 Sections 3.1.1 (plastic shrinkage reinforcement) and 3.1.2 (shrinkage and temperature reinforcement). MasterFiber F70 is designed to distribute quickly throughout the concrete mix. The fibrillation pattern is designed to optimize the mechanical bond between the mortar matrix and the fiber. MasterFiber F70 is an excellent temperature and shrinkage (secondary) reinforcement option when used at 1.5 lb/yd3 (0.9 kg/m3).
