| Abstract |
The permeation of methylene chloride and perchloroethylene through 7 protective clothing materials was studied to determine the permeation parameters, and to investigate the effect of solubility (polymer weight gain) and material thickness on the permeation parameters. The materials tested were two different nitrile rubbers, neoprene, Combination (a blend of natural rubber, neoprene and nitrile), two different polyvinyl chlorides, and polyvinyl alcohol. Methylene chloride permeated through all materials, except PVA, with breakthrough times of 2 to 8min, and permeation rates of 1250-5800µg/cm2.min. PVA and unsupported nitrile offered good protection against perchloroethylene with breakthrough time occurring after 2hr. Perchloroethylene permeated through the other materials with breakthrough times of 8 to 36min and permeation rates of 200 to 1600µg/cm2.min. For all material/chemical pairs, an increase in solubility increased the ratio of permeation rate to breakthrough time. An increase in thickness reduced the permeation rate and increased breakthrough time. |
