MasterFiber MAC 330

Synthetic Macrofiber

How does MasterFiber MAC 330 work?

​MasterFiber MAC 330 product is a high-performance polyolefin synthetic macrofiber with a twisted rope structure, engineered for use as a secondary reinforcement to control shrinkge and temperature cracking, and settlement cracking. MasterFiber MAC 330 product has been created specifically to replace welded-wire reinforcement (WWR) and reinforcing bars that are typically used as temperature and shrinkage reinforcement.​

Recommended uses

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

• Hard-troweled concrete

• Industrial and warehouse floors

• Residential and commercial slabs-on ground

• Concrete pavements

• Composite metal decks

• Architectural panels

• White topping/Overlays

What are the unique features of MasterFiber MAC 330 synthetic macrofiber?

• Uniform distribution throughout the concrete matrix

• Exceptional finishability

• Improves green strengths

• Alkali resistant and rust proof

• Improved post-crack flexural performance

What are the benefits of MasterFiber MAC 330 synthetic macrofiber?

• Eliminates the need for welded-wire reinforcement (WWR) and conventional steel bars used as shrinkage and temperature reinforcement, depending on application

• Reduces carbon footprint compared to convetional steel reinforcement

• Increases speed of construction

• Improves job site safety

• Reduces overall labor and material costs​

• Enhances concrete durability and impact resistance

• Lower paste demand compared to traditional synthetic macrofibers​​
