MemBack is a family of smooth, porous synthetic nonwovens that provide strong high-quality coating substrates for membrane casting for a broad range of membrane applications. MemBack products exhibit controlled pore size and excellent uniformity. Low bubble points and narrow pore size distributions promote excellent coating adhesion while minimizing strike-through, which can cause defects or low flux. Uniform caliper, flatness and excellent surface fiber tie-down create a superior surface that enables defect-free coating with uniform thickness and subsequent high-quality, hole-free membrane casting. High stiffness, strength, flatness and adhesion make MemBack an excellent choice for use as a membrane support in Reverse Osmosis, Nano, Ultra or Micro filtration applications.
