Product type
Meltblown filter fabric is a type of non-woven fabric produced through a meltblowing process, where thermoplastic polymers are melted and extruded through fine nozzles to create microfibers. These fibers are then collected on a conveyor belt, forming a web that is subsequently bonded together to create a porous material. The resulting fabric is known for its fine filtration capabilities and is often used in applications requiring high levels of air and liquid filtration.
| Material | Polypropylene or polyethylene |
| Fiber diameter | 1 to 10 microns |
| Weight | 20 to 200 grams per square meter (gsm) |
| Filtration efficiency | Up to 99% for particles larger than 0.3 microns |
| Thickness | 0.2 to 1.5 millimeters |
When selecting meltblown filter fabric, consider the specific application requirements such as filtration efficiency, weight, and thickness. It's important to specify the desired material grade, as well as any necessary certifications for medical or industrial use. Quantities should also be determined based on production needs, as bulk purchasing may affect pricing and lead times.
