    Synthetic hybrid fiber with optimum finishing performance

    How does MasterFiber MAC 360 FF work?

    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.

    Recommended uses

    Typical applications include, but are not limited to, the following:

    • Hard-troweled concrete
    • Industrial and warehouse slabs-on ground
    • Residential and commercial slabs-on ground
    • Concrete pavements, white-topping and overlays
    • Composite metal decks
    • Architectural panels

    What are the unique features of MasterFiber MAC 360 FF hybrid fiber?

    • Uniform distribution throughout the concrete matrix
    • Exceptional finishability
    • Improves green strength
    • Exceptional post-crack flexural performance
    • Alkali resistant and rust proof

    What are the benefits of MasterFiber MAC 360 FF hybrid fiber?

    • Enhances aesthetics and eliminates the potential for rust stains
    • Eliminates the need for welded-wire reinforcement (WWR) and conventional steel bars used as shrinkage and temperature reinforcement, depending on application
    • Provides effective tight crack control
    • Permits earlier stripping of forms, with less rejection
    • Minimizes plastic shrinkage and settlement cracking
    • Enhances impact and shatter resistance
    • Enhances durability
    • Reduces construction time and overall labor and material costs
