WDS Ultra
WDS® Ultra is a microporous insulation material which has an extremely low thermal conductivity coefficient giving it very good insulating properties. The product consists of inorganic silicate. The main constituent is fumed silica; the other components are opacifiers to minimize infrared radiation. Tried and tested applications for WDS® Ultra include insulation for heat-treatment furnaces in the aluminium industry, or back-up insulation in the industrial furnace industry.
