When is PPL-24® not an appropriate liner choice?

 Many liners, including PPL-24, would not be the most appropriate choice for certain applications. These might include situations where the liner will be exposed to the sun most or all of the time and still expected to last 20 years. 36 mil or 45 mil polypropylene, with its outstanding UV resistance would normally be the choice in this case. Another situation would be the nature of the material to be contained (primary). For primary containment of fuels and other hydrocarbons, one would normally think about urethanes. The chemical composition of the material to be contained must also be considered. The LDPE/HDPE composing the PPL-24 has a wide range of chemical resistance. Consult a good chemical resistance chart for specifics.
