Overview
PP Melt Blown Nonwovens are ultra-fine fiber nonwoven materials formed by polypropylene through the melt-blown process. They have a dense fiber web structure and are mainly used in applications such as air filtration, liquid separation, protective materials and adsorption media.
Product Features
High Filtration Efficiency
PP Melt Blown Nonwovens are produced using a meltblown process, with fiber diameters ranging from 0.5μm to 2μm. Combined with an electrostatic charging treatment, they achieve high filtration efficiency while maintaining low airflow resistance. Medical-grade products boast a bacterial filtration efficiency exceeding 99%, complying with EN14683:2003 standards. Industrial-grade products meet EN149 and NIOSH N95 certification requirements.
Electrostatic Treatment
After molding, the product undergoes an electret charging process to impart a stable electrostatic charge, enabling the material to retain particles for a long time, enhancing its capture efficiency for viruses, microorganisms, and suspended particles. This electrostatic layer maintains its effectiveness for over 12 months when stored at room temperature.
Stable Raw Material
Using food-grade polypropylene, free of plasticizers, heavy metals, or other additives, it meets the biocompatibility requirements of medical hygiene materials and poses no risk of irritation to skin or respiratory tract. It is suitable for applications requiring stringent material safety, such as medical masks and air filters.
Company Advantages
Precision Meltblown Equipment
The company uses high-temperature precision meltblown machines imported from Germany, equipped with digital temperature control and multi-hole spinnerets. This allows for stable fiber diameter control between 0.5 and 2 microns, ensuring uniform fiber structure in each batch.
High-Voltage Electret Process
Utilizing high-voltage electrostatic electret equipment, by adjusting the intensity and duration of the electric field, a persistent electrostatic charge is formed on the fiber surface. Combined with an electrostatic tester to monitor charge decay, this ensures long-term, stable filtration efficiency.
Complete Testing System
Equipped with professional airflow resistance testers and bacterial filtration efficiency (BFE) testers, each batch of products undergoes rigorous testing according to EN14683, EN149, and NIOSH standards, ensuring accurate data that supports buyers' quality requirements.
