SPECIAL FEATURES OF UNION CARBIDE CORPORATION CAL I DR IA ASBESTOS (a) Pelletized Material. The most Important contribution which Union Carbide.Corporation has made to the. safer use of asbestos is the introduction of pelletized products. "Calidria" Asbestos pellets reduce dust, cost less to ship and can lead to additional savings in handling and operating costs. The high purity and high fiber content of "Ca I i dr i Asbestos result from a proprietary hydraulic ore beneficI ation'process made practical by a unique chrysotile asbestos deposit near Coaiinga, California. Pelletized asbestos products are available only from Union Carbide. "Calidria" Asbestos pellets are nominally 1/2" long and 1/4" in diameter and have a buik density of 44 pounds/ft^. Although they contain no binder or other additive, the pellets have sufficient strength to minimize fracture during transport and handling. Some products are available in a "cracked" pellet form, in which the pellets have been coarse-ground to pass a 3-mesh screen. Both the pellet and cracked pellet form contain a negligble amount of minus 325-mesh dust, the major factor contributing to airborne contamination. The storage and feeding of pellets is simplified by their freeflowing, non-abrasive nature; and a cone-bottom bin with a 90 included angle will self-empty. Pellets can be handled and conveyed with almost any type of conventional equipment. The pellets are friable and can be fiberized with either wet or dry grinding equipment. (b) Packaginq. "Calidria" Asbestos pellets are normally packaged In 50 or 100 pound bags and are available in bulk hopper cars holding up to 90 tons. Arrangements can be made to supply pellets in other containers to suit customer requirements. Some products are available in "repulpable" or "beater" bags. These bags are pasted with water-soluble glue and printed with water-soluble Ink. They are used in the paper industry to permit adding bag and contents to the papermaking system. AlI products are packaged in 3-ply air-vented paper bags and some are sealed In polyethylene overwraps to prevent moisture penetration and dust re lease. Pallets of bagged products are made up of interlocking layers of bags with glue applied between layers to minimize load shifting. Full pallets can be covered with shrink-film or sturdy waxed cardboard protective shrouds. Most export shipments are made in containers which are loaded and sealed at the plant for delivery directly to the customer. UCC 016116 ^24-036
