Thermo-12 Gold is a pre-formed, high temperature, abuse-resistant pipe and block insulation with exceptional structural strength, composed of hydrous calcium silicate for use on systems operating up to 1200°F (650°C). It is inorganic, non-combustible, asbestos-free and meets or exceeds the physical and thermal property requirements of ASTMC533, Type 1. Integral to Thermo-12 Gold is XOX, a distinctive formula and process that inhibits corrosion to outside surfaces of pipe and equipment.
Because of its low thermal conductivity, durability, compressive strength and corrosion inhibiting properties, it is the preferred product for application on high temperature piping and equipment. Thermo-12 Gold is especially recommended for use in the petrochemical, power generation and process industries where piping and equipment operating up to 1200°F (650°C). The XOX corrosion inhibiting properties are not diminished by heating and cooling so the corrosion protection will continue for the life of the product. Thermo-12 Gold will not burn and may be used for fire protection in some applications.
