Asbestos square rope is a type of rope that is commonly used in various industrial applications due to its heat-resistant properties. It is made from asbestos fibers that have been woven together to form a dense, square-shaped rope. The asbestos fibers are mixed with other materials such as cotton or rayon to create a stronger, more durable rope. The rope is used to seal pipes, ducts, and boilers, where it provides an effective barrier against heat and gases. Asbestos square rope is used as an insulating material to protect equipment and personnel from high temperatures and flames.
