Are Poly-Flex liners resistant to chemical attack?
Chemical resistance as applied to geomembranes is a relative term. In its strictest form, chemical compatibility, as the term applies to this industry, implies that a chemical has no effect on the liner. However, from an engineering perspective, chemical compatibility means that a liner will survive exposure to a chemical, even though the chemical could have some effects on the liner, without causing the liner to fail. Poly-Flex liners provide a high degree of chemical resistance to a wide range of chemicals. • Which liner should be used for secondary containment, Poly-Flex HDPE or LLDPE? Why? Poly-Flex HDPE liners are preferred because most secondary containment projects are for emergency containment of chemicals at high concentrations, such as fuels and acids. The Poly-Flex HDPE liners provide a higher degree of chemical resistance as compared to LLDPE liners.
