Ny-Pro

Ny-ProTM is a monofilament nylon fiber designed to distribute quickly throughout the concrete mix. Ny-Pro fibers are primarily used as temperature-shrinkage reinforcement and plastic-shrinkage reinforcement in concrete. The fibers modify the macro and microcracking properties of the concrete, which significantly improves long-term durability.

Extensive testing has proven that Ny-Pro is an optimal alternative to welded wire mesh (WWF) as a temperature-shrinkage crack reinforcement in concrete.
