Made mainly (96 %) of high melting point Silica compound (Sio2-1600oC), it is also highly resistance to various corrosive acids. Natural properties together with special weaving gives insTEX ST600 a small coefficient of thermal expansion. It is thus able to survive sudden changes in temperature without tearing, significantly increase its value in the hot works area.

insTEX ST600 has a continuous temperature resistance of 1100°C and can provide effective resistance up to 1600°C for intermittent molten sparks. Its density also makes it light and flexible without losing tensile strength, ideal for protecting uneven surfaces from heavy molten metals.
