Abstract
The thermal insulating material of the present invention allows for the use of microballoons as an insulating material for the exterior surface of pipes. In the present invention, microballoons are mixed with a water based epoxy while in its liquid state. To absorb the water from the water based epoxy, cement is added to the mixture. The mixture of water based epoxy, microballoons and cement is then extruded or thrown onto the exterior surface of pipes.
