3. Technical Specifications

Note: Specifications are tested under standard conditions (ASTM D737 for air permeability, ASTM F2299 for filtration efficiency). Custom grades available upon request.

4. Application Scenarios

Our melt blown PP excels in a multitude of scenarios where precise filtration and barrier protection are paramount. In the medical sector, it serves as the core filter layer in surgical masks, N95 respirators, and isolation gowns, providing reliable defense against airborne pathogens and aerosols. Its high bacterial filtration efficiency (BFE >99%) makes it indispensable for healthcare settings worldwide.

In industrial air filtration, melt blown PP is integrated into HEPA filters, cleanroom systems, and automotive cabin air filters, effectively trapping dust, pollen, and PM2.5 particles. For liquid filtration, its hydrophobic nature supports applications in oil sorbents, wastewater treatment, and fuel filters, where it separates emulsions with minimal clogging.

Additional scenarios include personal protective equipment (PPE), such as face shields and coveralls; consumer products like vacuum cleaner bags and home air purifiers; and sanitary applications in diapers and feminine hygiene products for superior absorbency and leak prevention. The versatility of melt blown PP extends to electronics manufacturing for anti-static wipes and food packaging for breathable barriers, ensuring compliance with FDA and EU regulations.

5. Advantages

Choosing our melt blown PP offers distinct advantages over conventional nonwovens. The proprietary melt blowing technology produces a uniform fiber web with consistent pore sizes, resulting in predictable performance and reduced variability in end products. This leads to higher yield rates in downstream processing, such as mask assembly or filter lamination.

Compared to electret-treated alternatives, our melt blown PP maintains electrostatic charge stability even after aging or humidity exposure, ensuring long-term efficacy. Its lightweight yet robust construction minimizes material usage, lowering overall production costs without sacrificing quality.

Furthermore, we employ advanced electret charging processes to enhance filtration without compromising breathability, achieving optimal balance for user comfort and efficiency. Rigorous in-line testing for grammage, porosity, and efficiency guarantees batch-to-batch consistency, backed by third-party certifications like ISO 13485 and CE marking.

In terms of sustainability, our melt blown PP is fully recyclable and produced with low-energy processes, aligning with global ESG standards. Bulk packaging options reduce logistics costs, making it a cost-effective choice for international trade.

7. FAQ

Q: What is melt blown PP?

A: Melt blown PP is a type of nonwoven fabric made by extruding molten polypropylene through fine nozzles and attenuating it into microfibers using high-velocity air, creating a highly porous structure ideal for filtration.

Q: How does melt blown PP differ from spunbond PP?

A: Melt blown PP has finer fibers (1-5 microns) for superior filtration, while spunbond PP features larger fibers (15-35 microns) for strength and support layers. They are often combined in SMS composites.

Q: Is your melt blown PP suitable for medical masks?

A: Yes, our melt blown PP meets Type IIR EN 14683 standards with BFE/PFE >98%, suitable for surgical and FFP2/FFP3 masks.

Q: Can melt blown PP be customized?

A: Absolutely. We offer custom basis weights, widths, colors, and treatments like hydrophobic or flame-retardant finishes.

Q: What are the storage requirements for melt blown PP?

A: Store in a cool, dry place away from direct sunlight and humidity to preserve electret charge and fiber integrity. Shelf life exceeds 2 years under proper conditions.

Q: Do you provide test reports?

A: Yes, each batch includes detailed test reports for filtration efficiency, pressure drop, and tensile properties from accredited labs.
