Hengyong PP melt-blown filter media is made from special polypropylene resins by unique techniques with the high temperature melt-blown non woven technology.In particular,pleatable product has a higher 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 filter.
Hengyong's polypropylene melt-blown filter material covers a wide range of efficiency grade,F6 to Y11 for standard ventilation filter.

Product Performance:
1.The product is made from hydrocarbons with innocuity,insipidity,white and light character.
2.During combustion,PP produces only CO2 and water,this little impact is on the environment  
   compared with other plastics.
3.The electrets in PP,which enhance the capture performance of air filters,are stable.
4.PP is a fire-resistant material and may be used for manufacture UL-2 grade filters.
5.It is as well as water repellent material thus less troublesome with microorganisms.
6.Acid and alkali resistant,with high melting point(167-174)oC and stable performance.
