Melt-blown filter media by Handanhy had been engineered for consistent processing and excellent performance in stitched or ultrasonically sealed pleat filter designs.

Polypropylene Melt-Blown Filter Media

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.

Note

For the filters, different size is made up with different size of filter media. Even if with the same material, the filtration is different since of the different size. Users should choose the filter media according to their filter design and use condition, and then classify the efficiency in the application area.
