Membrane Backing Layer - MemBase™

Casted thin film composite membrane elements require high-strength materials capable of withstanding fast production speeds and high tensions.

Our MemBase™ membrane backing layer is a high-quality support that features a unique set of material properties designed to improve runnability in the casting process.


  • High web uniformity
  • No pinholes
  • No standing fibers
  • Less curling
  • Long uniform rolls


  • Improved adhesion with fewer membrane defects
  • Zero bleed-through for increased membrane efficiency
  • Reduction in quality defects in membrane casting
  • Reduction of edge curl under tension
  • Fewer changeovers increasing uptime
