See a live demo of the MAC 360 in application and learn a little more about how it can save you money. MasterFiber MAC 360 FF, a synthetic hybrid fiber, is manufactured from a proprietary blend of polypropylene resins for use in making fiber-reinforced concrete in compliance with the requirements of ASTM C 1116/C 1116M “Standard Specification for Fiber-Reinforced Concrete.” It is a blend of synthetic micro- and macrofibers engineered for use as shrinkage and temperature (secondary) reinforcement and, specifically, to provide optimum finishing performance in hard-troweled concrete applications. MasterFiber MAC 360 FF hybrid fiber has also been engineered to provide post-crack flexural performance equivalent to that provided by most commercially-available synthetic macrofibers, at equal dosages.
