PVA fibres are the new alternative to glass reinforcement for cement systems. It is a synthetic polyvinyl alcohol fibre whose chemical and physical characteristics make it particularly suitable for the Jesmonite family of polymer-modified cement materials. They have high strength combined with low elongation and high modulus. They offer advanced adhesion to the polymer cement matrix as well as inherent resistance to the degrading effects of the alkalinity of such a matrix. We strongly recommend their addition to Jesmonite systems to resist frost damage in the harshest outdoor environments.
