Casted thin film composite (TFC) membrane elements require high-strength substrate support materials capable of withstanding fast production speeds and high tensions. Revonex™ membrane backing paper is a membrane support substrate that features a unique set of material properties designed to improve runnability in the membrane casting process.
Revonex membrane backing paper overcomes many of the common issues experienced in the casting process, including lower production yield due to substrate defects, varying final membrane efficiency caused bleed-through from pinholes, scrap generated from substrate edge curling under high tension, and frequent downtime from short-length roll changeovers. The highly uniform web produces zero bleed-through, leading to improved adhesion in the casting process that ultimately generates higher yield and consistency of the final membrane. Available in long roll lengths with consistent flatness, you will experience more uptime and less scrap.
