Non-Woven Polyester Paper: What it is and How it Works


Non-woven polyester paper, a synthetic material made of continuous filaments bonded together, is an essential component in membrane manufacturing processes, particularly for separation membrane support. Crafted from 100% polyester fibers known for their remarkable mechanical properties, uniformity and smooth surface, this support sheet typically ranges in basis weight from 15 to 100 g/m², with an air permeability falling between 0.5 to 150 cc/cm²/sec.

Non-woven polyester paper finds its place as a critical component for flat sheet membrane casting systems, such as MEMS’ Semi Continuous Flat Sheet Membrane Casting System (FCS-330). This model offers a casting width of up to 300mm, making it compatible with a non-woven paper roll width of 330mm.


Non-woven paper offers several advantages in membrane production:


 1. Higher Sheet Uniformity: It ensures uniform membrane formation for reliable performance.


2. Mechanical Support: It maintains membrane integrity during the membrane flat sheet casting process.


3. Water Resistance: Exceptional resistance to water and dimensional stability. This characteristic is essential for membrane systems operating in harsh environments, ensuring long-term performance and durability.


4. Heat Resistance: Allows to withstand elevated temperatures encountered during membrane manufacturing processes


5. Chemical Compatibility: It's compatible with various casting solutions and conditions.


When using MEMS’ Flat Sheet Casting/Coating Membrane systems, non-woven paper stands out as an optimal choice for reinforcing UF/RO membranes due to its lightweight yet robust properties. Its inherent strength ensures minimal additional weight to the membrane system while providing essential reinforcement, contributing to structural stability. The paper's superior water resistance and dimensional stability are essential in upholding the integrity of the membrane support, particularly in demanding water treatment environments where durability is important.
