Table I The following chemicals do not attach or permeate high density crosslinkable polyethylene resins up to 100° F. Each application should be considered individually. All concentrations apply except where noted. Acetic Acid Aluminum Salts Alum Ammonium Hydroxide Ammonium Salts Amyl Alcohol Antimony Salts Arsenic Acid Barium Hydroxide Benzene Sulfonic Acid Bismuth Salts Boric Acid Bromic Acid Butanediol Butyl Alcohol Calcium Hydroxide Calcium Salts Chromic Acid<50% Citric Acid Copper Salts Detergents Diazo Salts Diethyl Carbonate Diethanol Amine Diethylene Glycol Diglycolic Acid Dimethylamine Dimethyl Formamide Ethyl Alcohol Ethylene Glycol Ferric Salts Ferrous Salts Fluoboric Acid Fluosilicic Acid Formic Acid Gallic Acid Gluconic Acid Hexanol Hydrazone<35% Hydrozine Hydrochloride Hydriodic Acid Hydrobromic Acid Hydrochloric Acid Hydrofluoric Acid Hydrofluorosilicic Acid Hydrogen Peroxide<52% Hydrogen Phosphide Hydroquinone Hypochorous Acid Iodine Solutions Lactic Acid Latex Lead Acetate Magnesium Salts Mercuric Salts Mercurous Salts Mercury Methyl Alcohol Methylsulfuric Acid Michel Salts Nicotinic Acid Nitric Acid<50% Oxalic Acid Perchloric Acid Phenol<10% Potassium Hydroxide Potassium Salts Phosphoric Acid Photographic Solutions Propyl Alcohol Propylene Glycol Sea Water Selenic Acid Sewage Silicic Acid Silver Salts Soap Solutions Sodium Ferricyanide Sodium Ferrocyanide Sodium Hydroxide 'Sodium Hypochlorite<9% Sodium Salts Sodium Sulfonates Stanic Salts Stannous Salts Starch Solutions Stearic Acid 'Sulfuric Acid <80% Sulfurous Acid Sugar Solution Glucose Lactose Sucrose, etc. Tannic Acid Tanning Extracts Tartaric Acid Titinium Acid Toluene Sulfonic Acid Triethanolamine Urea Vinegar Wetting Agents Zinc Salts ' Concentrations above stated per- centage require special considera- tions, contact factory for guidelines concerning these applications. The following oils and organic chemicals do not Fatty Mineral Animal Vegetable attack HDXLPE resins. They will be absorbed into Acids Oils Fats Oil the wall of the tank; however, there should be no Butyric Lube Lard Corn loss of chemical. Because of this absorption, no Lauric Transformer Fish Oil Coconut chemical other than the original should be stored in Linoleic Hydraulic Musk Oil Cottonseed the tank as long as contamination may result as the Oleic Whale Oil Olive absorbed oil is leached out. Storage at Palmitic Peanut temperatures up to 100° F are possible provided the Stearic effects of the absorption on the properties of the tank are not prohibitive. Table III The following organic chemicals do not attack high density crosslinkable polyethylene resins. They will be absorbed into the wall of tank and a permeation loss will occur. Because of this permeation and the effect it has on the physical properties of the tank, it is generally not recommended that these chemicals be storage at room temperatures above 100° F. However, their use largely depends on such factors as size of tank, its location, toxicity of the chemical, and applicable codes such as NFPA, OSHA, etc. Anitine Benzene Carbon Tetrachloride Chlorabenzene Cychohexanol Cycolohexnone Dibutylphthalate Diesel Fuel Dimethylamine Ethyl Butyrate Ethylene Chlorohydin Fuel Oil Fufural Aliphatic Hydrocarbons (hexane, octane, hexene, octene, etc.) Jet Fuel Gasoline Nitrobenzene Octyl Cresol Propylene Dichloride Toluene Xylene This document reports accurate and reliable information to the best of our knowledge, but our suggestions and recommendations cannot be guaranteed because the conditions of use are beyond our control.
