Macro Synthetic Fibres

Macro Synthetic Fibres (MSF) are a more recent development, with their initial introduction to the market occurring in the late 1990’s. High performance macro synthetic fibres are typically made of polypropylene and are able to be manufactured with a high tensile strength of more than 650 MPa.

The base material, polypropylene, makes them inert to chemical attack such as corrosion caused by chloride ions. Thus, they are an excellent choice for shotcrete reinforcement, as shotcrete is often used in very aggressive environments such as deep mines, tunnels below the water table or in slope protection along traffic ways using salt for deicing.
