We provide an extensive range of glass and silica fabrics for high temperature heat protection. Our coatings and dips are formulated with dispersions of vermiculite, silica and graphite.
Glass fabrics have a temperature maximum of 550˚C. On dipping with dispersions of silica and graphite these fabrics provide protection at continuous temperatures of 700˚C. Vermiculite dipped glass fabric can provide protection at even higher temperatures.
Silica fabrics resist temperatures up to 1000˚C. The addition of vermiculite coating gives resistance to higher temperatures for a short period. Graphite dipped silica fabric improves the dynamic and abrasion resistance and improves the longevity of the part in some applications.
Weavelocking of glass fabrics using polymer formulations locks the fibres together in the fabric. The fabric does not fray on cutting and is more easily fabricated into parts. The pick-up concentration can be varied, giving the right stiffness and handleability for the customer’s application. Weavelocking on its own does not increase the temperature rating of the glass fabric.
