PVA fibres are added to Jesmonite AC730 as an alternative to glass fibres in all cast products such as garden ornaments and cast decorative panels.

They are characterised by good adhesion and dispersion in Jesmonite composites, and by their high tensile strength and low elongation.

PVA fibres will lead to improved flexural strength, and will help resist cracking and surface crazing in cast products.

Typical addition rates are 1% – 2% of total mix weight.
