Chemical effect (see discussion on Chemical Resistance) No Effect--Most chemicals of this class have no or minor effect. Oxidizer--Chemicals of this class will cause irreversible degradaton. Plasticizer--Chemicals of this class will cause a reversible change in physical properties. Chart Rating Most chemicals of this class have little or no effect on the liner. Recommended regardless of concentration or temperature (below 150° F). Chemicals of this class will effect the liner to various degrees. Recommendations are based on the specific chemical, concentration and temperature. Consult with Poly-Flex, Inc. Chemicals of this class at high concentrations will have significant effect on the physical properties of the liner. Generally not recommended but may be acceptable at low concentrations and with special design considerations. Consult with Poly-Flex, Inc.
