Meltblown Membrane

What is Meltblown Membrane?

The Meltblown Membrane applied in water filtration is an ultra-fine fibrous filtering material produced via the melt-blowing process, specifically designed for liquid purification. Its core feature lies in removing suspended solids, particles, colloids, microorganisms, and other impurities from water through physical interception and adsorption.

Why choose Srilan’s Meltblown Membrane？

Meltblown Membrane is the core product of Srilan. By choosing Srilan, you can benefit from the following:

No Fiber Shedding.Srilan’s Meltblown Membrane undergoes calendering treatment, eliminating fiber shedding at its source. It ensures that zero fiber release during filtration, preventing secondary contamination of filtrates. Even under high-flow scouring, the fiber structure remains intact and the filtration accuracy will not decline due to fiber loss.

Diverse Options.Srilan offers a variety of Meltblown Membranes made from different materials, including PP, PBT, PET, nylon, etc., to meet diverse market demands.

High Flux Performance.Srilan’s Meltblown Membranes features a 3D interlocking network of ultra-fine fibers, creating a porous structure with short water flow paths.By precisely adjusting fiber density, the membrane achieves gradient pore distribution. This design minimizes clogging and extends high-flux durability.

Excellent Chemical Stability.The SrilanPP Meltblown Membrane is made of polypropylene (PP) base material, which can withstand acidic and alkaline environments with a pH range of 1 to 14. It is resistant to inorganic acids (such as sulfuric acid and hydrochloric acid) and organic solvents (such as alcohols) below 80℃.

High-Precision Filtration Capability. The fiber gaps of Srilan’s Meltblown Membrane can retain micron-sized particles, effectively removing bacteria, viruses, suspended solids and impurities from liquid. Pollutants are deeply adsorbed by the fibers and are not easily released due to fluctuations in flow rate.
