FILE NAME: Union Carbide (UC) DATE: 0000 DOC#: UC110 DOCUMENT DESCRIPTION: Industry Sales Information - Why is 'Calidria' Asbestos Different W hy is "Calidria" asbestos different? "Calidria" products are made from high-purity, short-fiber chrysotile asbestos obtained from a unique deposit about 160 miles south of San Francisco, California. Unlike conventional deposits that extend through the host rock, this deposit is essentially free of hard, consolidated rock masses. Further, the ore assays up to 60% asbestos compared to conventional deposits which contain from 6 to 10% asbestos. Special hydraulic beneficiation techniques develop ed by Union Carbide efficiently break down the fiber bundles and remove the rock and impurities from the asbestos fiber. As a result, all "Calidria" products are over 95% pure asbestos whose fibers are 98% liberated from fiber bundles. SG-210 is finely ground for use in tape-joint compounds. C A N A D IA N A S B E S T O S -A S - M IN E D -I n d iv id u a l flbar bundles are straight and tightly bonded, surrounded by consolidated rock masses. In th is form , the fibers defy separation from each other and from the host rock. " C A L I D R I A " A S B E S T O S - A S-M IN E D - Here the fibers are random ly oriented and essentially free of hard rock masses. Further, the ore assays up to 60% asbesto, consider ably more than the Canadian ora. " C A L ID R I A " A S B E S T O S - IF D R Y -P R O C E S S E D - Even the m ost exacting dry processes da not com pletely break dow n the fiber bundles into individually liberated fibers. Union Carbide technology developed a special wet process to liberate the fibers. "C A L ID R IA " ASBESTOS - U N IQ U ELY W ET-PROCESSED -- Union Carbide's process separates 98% o f the fibers from the fiber bundles. The fibers contain virtually no rock dust, abrasive fillers, or im purities that can mar tape-joint compounds. \ UCC 005942
