Polypropylene Melt-Blown Filter Media
Melt-blown filter media by Handanhy had been engineered for consistent processing and excellent performance in stitched or ultrasonically sealed pleat filter designs.
Product Introduction
Handanhy PP melt-blown filter media is made from special polypropylene resins with unique techniques, using high temperature melt-blown non-woven technology. In particular, pleatable products have a higher tensile strength, higher break endurance and higher stiffness, which is critical in making mini-pleat filters, e.g. V-bank ventilation filters, air filters for automobile cabinets, filters for vacuum cleaners and various household filters. Our melt-blown filter media is highly efficient with a high capacity for holding dust, and also offers minimal airflow resistance. Top-class engineering provides for smooth, consistent performance.
Handanhy’s polypropylene melt-blown filter material covers a wide range of efficiency grades, F6 to Y11, for standard ventilation filters.
Product Performance
-
The product is made from harmless, eco-friendly hydrocarbons with white and light characteristics.
-
During combustion, PP produces only CO2 and water, which has little impact on the environment compared with other plastics and related materials.
-
The electrets present in PP, which enhance the capture performance of the air filters, are quite stable.
-
Poly-Propylene melt-blown filter media is majorly used in power generation, commercial and industrial sectors
-
PP is a fire-resistant material and may be used to manufacture UL-2 grade filters.
-
It is also a water repellent material, and thus less troublesome when it comes to considering microorganisms.
-
Acid and alkali resistant material, with high melting point (167-174)℃ and stable performance.
