Durafiber-X has upward of 1.3 billion fibers (3mm), which is approximately 10x the number of fibers per pound of polypropylene and even higher than glass fiber and basalt. 

Durafiber-X’s specific gravity of 1.17 gives it unique properties that neither float nor sink. Instead, it suspends itself evenly throughout a mixture and bonds actively with cement, unlike inert fibers.

The fiber’s PAN acrylic surface chemistry features a free-standing carbon ion, allowing it to chemically react and bond with the cement during the hydration process.

As the cement hydrates, it forms a matrix that physically interlocks with the vast number of fibers, creating an incredibly strong and durable composite material. As a result, a highly durable modulus cement forms, helping to slow down losses. 

Durafiber-X can be dosed in a bulk plant for consistent loadings or hand-dosed onsite in cement and spacers. This, plus its strength, makes it the best possible fiber replacement for rebar downhole.
