Physical properties were determined on specimens prepared under laboratory conditions using applicable ASTM procedures. Actual field conditions may vary and yield different results; therefore, data are subject to reasonable deviation.
Sauereisen Sheet Membrane 90 is an impervious synthetic elastomer of uniform quality and thickness for use in corrosion- resistant construction. It is a fiber-reinforced poly-tetra-fluoro-ethylene (PTFE) lining system. 90 replaces rubber, plastic and asphalt membranes commonly used on floors, tanks and process vessels, between substrate and acid/alkali-resistant brick.
The elastomeric sheet membrane remains flexible over a temperature range of -20° to +200°F. Thus, when the substrate moves, the membrane serves as a sheer pad between it and the brick lining. 90 is an easy-to-install, single-layer system which resists water, oil, most alkalies and acids. It will protect the substrate from corrosive chemical attack.
