Product Overview
High Filtration Meltblown Nonwoven Fabric is a premium-grade filtration media manufactured via advanced meltblown technology using 100% high-purity Polypropylene (PP) resin. Featuring a dense matrix of micro-fine fibers and an optimized electrostatic charge, it delivers exceptional filtration efficiency (BFE up to 99%, PFE up to 95%-99%) and minimal air resistance against dust, bacteria, aerosols, and viral particles. Engineered for high-stakes applications, it is widely utilized in medical protection, industrial respirators, HVAC systems, and high-end air purification.
Key Features
Superior Filtration Efficiency: BFE/PFE/VFE up to 99%, fully compliant with global medical and industrial respiratory standards.
Micro-Fine Fiber Structure: Fiber diameters of 1–5 microns create a highly efficient mechanical barrier network.
Advanced Electret Technology: Equipped with advanced Corona and Hydro-charging technology to ensure minimal charge decay and an extended shelf life.
Low Pressure Drop: Optimized breathability lowers inhalation resistance, enhancing comfort without sacrificing filtration performance.
High Consistency & Uniformity: State-of-the-art production lines ensure uniform web distribution (GSM) and stable performance across every roll.
Biocompatibility & Chemical Safety: Certified for skin irritation and cytotoxicity under ISO 10993. Free from heavy metals and plasticizers, fully compliant with OEKO-TEX Standard 100, REACH, and RoHS directives.
Full Customization: Tailored basis weight (10–80 gsm), roll width, and colors to match varied automatic mask-making and pleating production lines.

FAQ
Q: What standard test flow rates do you use to measure filtration efficiency?
A: We test our medical-grade meltblown at a flow rate of 32 L/min (BFE/PFE) and our respirator-grade (N95/FFP2) at 85 L/min or 95 L/min using NaCl and Oil aerosols on TSI 8130A testers, matching NIOSH and EN149 standards perfectly.
Q: How do you solve the charge decay problem of meltblown fabric over long shipments?
A: We utilize premium electret masterbatches and advanced Hydro-charging (water-method electret) technology. This embeds a deep, stable electrostatic charge inside the microfibers, guaranteeing that the filtration efficiency remains stable even after long-term overseas transit and up to 2-3 years of storage.
Q: Can we request third-party test reports (SGS/TUV) before placing a bulk order?
A: Absolutely. We can provide our recent technical data sheets and SGS/TUV compliance certificates. We also offer free sample rolls for your internal machine testing and validation.
Q: How do you ensure price stability and supply continuity during global market fluctuations?
A: We maintain long-term, direct strategic partnerships with top-tier global PP resin producers. With an extensive monthly production capacity, we guarantee stable raw material costs, priority allocation, and uninterrupted mass supply even during peak seasons.
