ARMOR FIBER PF 54, a synthetic macro fiber produced and distributed in the USA, available from American Flooring Products, is an easy-to-finish, 100% virgin copolymer/polypropylene fiber. Its long-braided monofilament is a unique blend of high-strength polymers.
It is a self-fibrillating fiber that improves the mechanical properties of concrete including: toughness (energy absorption after cracking), This high strength synthetic macro fiber offers maximum long-term durability, increased impact strength, fatigue resistance and resistance to plastic shrinkage cracking, ARMOR FIBER PF 54, is non-corrosive, non-magnetic and 100% acid and alkali resistant.
The exceptional bond strength of ARMOR FIBERPF 54 fibers within the concrete matrix is the result of their unique ability to partially fibrillate upon mixing. After mixing, each fiber transforms into a fiber with fibrils at the ends that act as mechanical anchors, providing a bonding capacity that optimizes the material properties of each strand and provides enhanced structural properties to the concrete

Advantages
- Improves plastic cracking control, more effective than other steel options including metallic fibers.
- Reduces segregation
- Homogenizes and distributes exudation water better (uniform exudation).
- They are neither alkaline nor conductive.
- Protects the structure from fire.
- Restricts warping.
- They are pumpable.
- Due to the number of fibers /kg there is a more efficient control of cracking by drying.
- The surface finish is outstanding.
