　　Deteriorating／damaging effects of moisture can occur with certain plastics.For high—moisture applications， polyphenylene oxide， polysulfone， acrylic， butyrate， diallyl phthalate， glass—bonded mica， mineral—filled phenolic， chlorotrifluoroethylene， vinylidene， chlorinated polyether chloride， vinylidene fluoride， and the fluorocarbons should be satisfactory.Diallyl phthalate， polysulfone， and polyphenylene oxide have performed well with moisture／steam on one side and air on the other （a troublesome combination）， and they also will withstand repeated steam autoclaving.Longterm studies of the effect of water have disclosed that chlorinated polyether gives outstanding performance.Impact styrene plus 25 wt% graphite and high—density polyethylene with 15% graphite give long—term performance in water.

　　Depending on what is required， the different plastics can provide diFfercnt rates of permeability properties.As an example， certain polyethylenes will pass wintergreen， hydrocarbons， and many other chemicals.It is used in certain cases for the separation of gases since it will pass one and block

　　another.Chlorotrifluoroethylene and vinylidene fluoride， vinylidene chloridc， polypropylene， EVA， and phenoxy merit evaluation.
