Question 1

What is the difference between meltblown liquid filtration membranes and conventional nonwoven fabrics?

Accepted Answer

Meltblown membranes for liquid filtration are designed to capture fine particles and bacteria in flowing liquids, while conventional nonwovens are typically used as support or pre-filtration layers.

AF-1400 and AF-2100 feature membrane-grade structures with enhanced surface uniformity and chemical stability.

Question 2

Can this material be used for drinking water or food-grade applications?

Accepted Answer

Yes. We use food-contact-grade polypropylene (PP) raw materials. However, the complete filtration system must still meet applicable NSF standards or local drinking water regulations before use.

Question 3

What are the typical pore sizes of AF-1400 and AF-2100?

Accepted Answer

Pore sizes vary depending on fabric weight and manufacturing conditions, typically ranging from 2 to 20 μm.

Question 4

Can these membranes be used in backwashable or reusable filtration systems?

Accepted Answer

PP and PBT offer good mechanical strength and chemical stability, making them suitable for low-pressure backwashing or surface cleaning.

For repeated use, a multilayer support structure is recommended to help prevent tearing.

Question 5

What chemicals and operating conditions can these materials withstand?

Accepted Answer

PP and PBT offer resistance to acids, alkalis, salts, and many organic solvents, such as ethanol and acetone.

An operating temperature below 90°C is recommended to help maintain pore size stability and extend service life.

Question 6

Can the membranes be customized with different thicknesses or multilayer structures?

Accepted Answer

Yes. Thickness can be adjusted from 0.06 to 0.20 mm, and the material can be laminated into two- or three-layer structures for gradient filtration or enhanced mechanical support.

Question 7

Can the membranes be laminated with other materials, such as PET or activated carbon fabric?

Accepted Answer

Yes. Heat lamination or adhesive bonding can be used to create multifunctional filtration layers, such as PP with PET support mesh or PP with an activated carbon layer.

We also offer customized lamination and sample development services.
FAQ 08

Question 8

How do meltblown liquid filtration membranes perform in terms of flow rate and pressure drop?

Accepted Answer

Performance varies depending on fabric weight, pore size, and operating conditions, such as water quality and pressure.

We can provide sample rolls for laboratory testing and assist customers in evaluating suitable filtration and pressure drop parameters.

Question 9

Can you provide third-party testing or SGS reports?

Accepted Answer

Yes. We can arrange third-party physical and chemical testing upon request, including pore size distribution, tensile strength, and RoHS/REACH compliance testing.

Question 10

What are your minimum order quantity (MOQ) and lead time?

Accepted Answer

Our standard MOQ ranges from 2,000 to 10,000 m², with a typical lead time of 3–5 weeks.

For special specifications or additional lamination processes, the delivery schedule will be confirmed after the design requirements are finalized.
