Product Introduction
Industrial Filtration Meltblown Nonwoven Fabric is an engineered microfiber medium manufactured through high-precision extrusion and advanced thermal airflow attenuation using premium thermoplastic polymers. With fiber diameters strictly controlled between 1 and 5 microns, this material forms a dense, three-dimensional interconnected pore network that delivers exceptionally high specific surface area and structural uniformity.
By optimizing the polymer's crystalline molecular weight and leveraging advanced dual-beam manufacturing technology, this industrial-grade meltblown media achieves an optimized balance between maximum fractional particle capture efficiency and ultra-low air resistance (low pressure drop). This optimal aerodynamic performance significantly reduces energy consumption and operational costs in industrial ventilation, dust collection, and HVAC systems. Fully customizable in efficiency grades, mechanical stiffness, and surface treatments, it serves as the core filtration layer in critical environments, including cleanrooms, automotive systems, liquid purification, and oil-water separation.

FAQ
Q: What specific filtration standards can this meltblown media achieve?
A: This media can be custom-engineered to meet various global standards, including MERV 11 to MERV 16 (ASHRAE 52.2), ePM1 / ePM2.5 / ePM10 (ISO 16890), and EPA/HEPA grades E11, H12, to H13 (EN 1822). The GSM and electret levels are meticulously balanced to match your target pressure drop.
Q: How does the fabric behave during high-temperature laminating processes?
A: The material is produced from premium narrow-molecular-weight polypropylene which provides a highly stable thermal melting window. The fabric exhibits minimal thermal shrinkage and excellent interfacial bonding strength when combined with spunbond (PP), needle punch, or fiberglass mesh via ultrasonic welding or EVA/PUR hot-melt adhesives.
Q: Is this material safe for sensitive applications like food processing, pharmaceutical, or electronic cleanrooms?
A: Yes, absolutely. The material is made from 100% virgin PP without any recycled content. It is fully RoHS and REACH compliant, 100% silicon-free, and does not shed fibers or outgas organic compounds. This makes it ideal for high-purity cleanrooms and regulated secondary processes.
Q: What support is offered for new product development and engineering qualification?
A: A fast-track sample service is available providing 20 to 50 meter prototype rolls for your engineering qualification and trial pleating runs. Additionally, all bulk orders are delivered with a full technical data package including a detailed Technical Data Sheet (TDS), Material Safety Data Sheet (MSDS), and a Certificate of Analysis (COA) per batch.
Q: What is the standard lead time and global delivery capability?
A: Standard lead time is 7 to 15 days depending on the volume and customization specifications. Orders are shipped with robust global export support, featuring seaworthy pallet packaging (PE wrapping film and moisture-proof protection) experienced in fast-track international customs clearance.
