TANK RESIN SELECTION GUIDE<br />
.<br />
• Both operating conditions and type of chemical can decrease maximum service temperatures.<br />
• Some fi ttings of these resins are FDA–acceptable.<br />
• Regardless of resin, black–pigmented tanks are strongly recommended for outdoor use.<br />
• Continuous service temperatures in ranges above ambient can affect tanks in at least two ways: 1) the useful life of the tank may be<br />
shortened; and 2) the ability of the container to maintain its shape may decrease, perhaps resulting in distortion.<br />

Advantages: Excellent impact resistance. Suitable for many corrosives not handled by fi berglass-reinforced polyester (FRP). Outstanding weatherability.<br />
Applications: Storage of many corrosives, including sulfuric, hydrochloric, and hydrofl uoric acids, and sodium hydroxide. Storage of organic/inorganic<br />
chemicals/compounds. Storage of sodium hypochlorite. Storage of boiler treatment chemicals. Water/sewage treatment. Outdoor use.<br />
Not Generally Recommended for: Strong oxidizing agents, aromatic hydrocarbons, halogenated aliphatic hydrocarbons, liquefi ed petroleum gas, solvents.<br />

Notes:<br />
1 XLPE is recommended for use with stress-cracking agents.<br />
2 Brittleness temperature per ASTM test D-746. The impact resistance of most rotomolded tanks declines at freezing temperatures. XLPE tanks are well-suited for<br />
outdoor storage in winter.<br />
3 LLDPE and HDPE tanks comply with FDA Regulation 177.1520; PVDF tanks comply with FDA Regulation 121.2593.<br />
4 Open-top tanks should be black for outdoor use. Only tanks which are UV-stabilized may be used outdoors.
