Melt Blown Nonwoven Fabric: Superior Filtration and Protection Solutions

Product Overview

Our melt blown nonwoven fabric represents the pinnacle of advanced filtration media, engineered through the precision meltblowing process. This high-performance material is produced by extruding molten polymer fibers—typically polypropylene—into fine, continuous filaments that are collected on a moving screen, creating a web of microfibers with diameters as small as 1-5 microns. The resulting melt blown fabric offers exceptional barrier properties, making it ideal for demanding applications in air and liquid filtration, medical protection, and industrial safety.

What sets our melt blown fabric apart is its optimized structure, which balances high filtration efficiency with low pressure drop. Available in various grammages from 10gsm to 100gsm, our melt blown products are customizable to meet specific performance requirements. Whether you're manufacturing N95 respirators, HEPA filters, or oil-absorbent pads, our melt blown nonwoven delivers reliable, consistent quality backed by rigorous testing to international standards like ASTM F1862 and EN 13274-1.

In the global market for nonwoven materials, melt blown fabric has become indispensable due to its lightweight, breathable nature and superior particle capture. Our production facilities employ state-of-the-art meltblowing lines, ensuring uniformity in fiber distribution and enhanced electrostatic charging for electret-treated variants, which boost filtration efficiency up to 99.99% for 0.3-micron particles.

Technical Specifications

Note: Specifications are subject to customization. All melt blown fabrics undergo strict quality control, including 100% online monitoring for uniformity.

Application Scenarios

Our melt blown nonwoven fabric excels in a wide array of scenarios where superior filtration and barrier protection are critical. In the medical sector, it serves as the core filter layer in surgical masks, N95/FFP2 respirators, and protective gowns, effectively blocking bacteria, viruses, and droplets. Industrial applications include HVAC air filters, automotive cabin filters, and cleanroom barriers, where its high dust-holding capacity ensures prolonged performance.

For liquid filtration, melt blown media is widely used in water treatment cartridges, oil-water separators, and fuel filters, capturing fine particulates and emulsions with minimal clogging. In the hygiene industry, it enhances absorbent cores in diapers and sanitary products for improved fluid lock-in. Additionally, flame-retardant grades find use in welding curtains and battery separators, while hydrophobic variants are perfect for spill control mats in marine and petrochemical environments.

• Personal Protective Equipment (PPE): Face masks, respirators
• Air Purification: HEPA filters, vacuum bags
• Liquid Filtration: Microfiltration membranes, coalescers
• Industrial Wipes: Absorbent and low-lint cleaning materials

Advantages

Choosing our melt blown fabric provides distinct competitive edges over conventional materials. Its microfiber entanglement creates a tortuous path that mechanically and electrostatically traps contaminants, outperforming spunbond or SMS fabrics in fine particle filtration. The material's inherent breathability reduces user fatigue in PPE applications, while its thermal bonding eliminates the need for adhesives, ensuring purity and recyclability.

• Cost-Effective High Performance: Achieves premium filtration at competitive pricing through efficient production scales.
• Consistent Quality: Advanced meltblowing technology with real-time fiber diameter control minimizes batch variations.
• Enhanced Safety: Low shedding and biocompatibility for skin-contact uses; meets FDA and CE requirements.
• Scalable Supply: Monthly output exceeding 500 tons, supporting large-scale B2B orders.
• Innovation-Driven: Ongoing R&D for antiviral coatings and biodegradable alternatives in melt blown formulations.

FAQ

What is melt blown fabric and how is it made?

Melt blown fabric is a type of nonwoven material produced by melting polymer resins, extruding them through fine nozzles into hot air streams to form microfibers, which are then randomly laid onto a collector belt. This process yields a highly porous yet efficient filter media.

What are the main differences between melt blown and spunbond fabrics?

While spunbond features larger fibers (15-30 microns) for strength and durability, melt blown has finer fibers (1-5 microns) optimized for filtration, often layered together in SMS composites for balanced properties.

Is your melt blown fabric suitable for medical-grade masks?

Yes, our high-efficiency melt blown grades meet or exceed Type IIR, KN95, and FFP2 standards, with verified BFE/PFE ≥98% and low breathability resistance.

Can melt blown fabric be customized for specific applications?

Absolutely. We tailor grammage, electret charging, surface treatments (e.g., hydrophobic), and colors to match your exact needs, with minimum order quantities as low as 500kg.

What is the shelf life of melt blown nonwoven fabric?

Under proper storage conditions (cool, dry, away from sunlight), our melt blown fabric maintains filtration performance for 2-5 years, depending on electret treatment.

Do you offer samples of melt blown fabric?

Yes, free samples are available for qualified B2B inquiries, typically 1-5 meters per grade, shipped within 3-5 days.
