The objective of this study was to provide a source of compatibility data between commercially available polymeric and elastomeric materials and solvents used in the Agricultural Chemical Industry The following solvents were selected: aromatics; alkylbenzene predominantly C10, alkylnaphthalene predominantly C10–12, naphthalene depleted alkylnaphthalene C11–12, aliphatic; aromatic free C11–12 hydrocarbon solvent, isoparaffin; primarily C14 and C23 paraffinic petroleum oil These solvents were tested with the following materials: high density polyethylene, fluorinated high density polyethylene, polyvinyl chloride, nitrile butyl rubber, ethylene propylene rubber, polychloroprene, perfluoroalkoxy resin, and vinylidene fluoride.
The results of the elastomeric tests showed that perfluoroalkoxy and vinylidene fluoride resins are excellent choices for all of the solvents tested, ethylene propylene rubber was shown to be the poorest choice of all With respect to the polymeric tests, the second and third degree fluorinated high density polyethylene materials were compatible with all of the solvents. Polyvinyl chloride, however, was not compatible with aromatic solvents
As a word of caution, the information in this paper can only be used as a starting point in the selection of polymeric and elastomeric materials with compatible Ag-Chem solvents The Agricultural Industry must combined this information with additional information such as choice of active ingredients, surfactants, and application systems before the final selection of packaging and seal materials can be made
