Our traditional feed-type vulcanization technology
Belt-type rubber expansion joints are the result of rubber, cloth material, and rope vulcanized using feed-type technology. This feed-type vulcanization is a traditional technology built up through our long history of molded rubber production. For products that are over 30 meters in length, portions are repeatedly fed and vulcanized after preliminary molding .
