Made mainly (96%) of high melting point Silica Compound, it is also highly resistance to various corrosive acids. Natural properties together with special weaving gives insTEX ST1300 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 work area.

insTEX ST1300 has 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.
