It's heat-weldable; easy to use; non-toxic; sustainable; flexible; lightweight; malleable; moldable & durable. Leadax™ is made up of expanded aluminum mesh reinforcement bonded with a lonolithic layer of modified polyvinyl butyral (PVB). A release liner of each side of the material roll makes unrolling material simple and includes a printed grid for accurate cutting.
