​MasterFiber MAC 360 FF

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
