What is Melt-blown filter cartridge

The way to extrude the polymer without any woven process is melt-blown process.To simplify this process,you can think it as melt those materials down and then cure it togetther in a low temperature. Theoretically, any thermoplastic can be used in the melt-blown process. Then these materials can be made into the high efficiency fuilter. In so many chemical materials, the polypropylene is the most widely used raw material for melt blown process. Normally, the melt blown material are polyester, polyamide, polyethylene, PTFE, polystyrene, PBT, EMA , EVA, etc. Olefin polymer raw materials (such as polypropylene) have a high degree of polymerization, so the heating temperature is higher than its melting point by more than 100 °C to be able to melt blown smoothly, while the heating temperature of polyester is slightly higher than its melting point.

Yitong melt-blown filter cartridgesare made of avirulent and flavorless polypropylene particles, after several process like,heating, melting, spinning, drawing, forming to tubular deep filter cartridge. The melt-blown filter cartridge have an outstanding chemical resistance and strong pollutant carrying capacity. The melt-blown filter cartridge has a durable service life and cost effective advantages. The melt-blown filter cartridge provides a depth loading liquid filtration at ratings from 1 micron to 100 micron. Thus the melt-blown filter cartridge offer a consistent of dirt loading throughout the usage of the filter cartridge.
