Product Description
Calcium silicate is used to insulate high-temperature pipes and equipment and for fire endurance applications. It is manufactured in three different forms: preformed block, preformed pipe, and board. It is noted for its high compressive strength, corrosion-inhibiting properties, and high-temperature structural integrity - 1,200°F (Type I, for pipe and block) or 1,700°F (Type II, fire endurance boards).
Calcium silicate is typically applied on high-temperature (greater than 250°F) pipe and equipment in industrial facilities, such as chemical plants, refineries, and steam electric power plants. Since it is a rigid material that has a relatively flat thermal conductivity curve, extremely high compressive strength, high flexural strength, a Class A rating for Flame Spread/Smoke Developed, and is noncombustible , it is widely used in high-temperature, industrial applications subject to physical abuse
Due to its high compressive strength (greater than 100 psi), high flexural strength (greater than 50 psi), and resistance to damage from tumbling, plus its ability to maintain those properties over time up to its rated 1,200°F, calcium silicate can withstand considerable physical abuse without loss of insulating efficiency. In addition, calcium silicate can withstand vibration induced by high-temperature steam flow around internal pipe obstructions, such as valve internals, measuring devices, and flow restriction orifices."

ADVANTAGES • Excellent resistance to damage enhancing the life of the system. • Inhibits corrosion on carbon steel and stainless steel piping and equipment. • Consistent thermal performance to 1200°F(650°C). • Noncombustible Insulation. • Structural strength protects against damage to lagging. • Asbestos, Mercury and Lead Free. • No organic binders; No loss of insulation integrity due to binder burn out. • Large selection of sizes and forms.
