Calcium Silicate

Calcium silicate (CalSil) 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).
