Silica cloth with vermiculite is made with silica yarns. The silica yarns are made of continuous glass fibres with a diameter of 6 µm and over, and with an additional treatment to increase the overall proportion of SiO2 to over 94%. The product is used as a reinforcement for composite materials, and as an acoustic, thermal, hydraulic and electrical cable protection insulator. Under normal conditions it has good chemical stability. Vermiculite improves the cloth’s physical, mechanical and thermal insulating properties. Impregnating with vermiculite helps to prevent fraying on cutting when making manufactured articles.
Applications
Silica cloth is used in the form of: insulation of hightemperature furnaces and turbines, covers to protect against metal splash and sparks, furnace curtains, blankets for removable lagging, sleeves for piping, compensators.
