Polypropylene Needle Felt

Capable of manufacturing standard PP product 15,000 squares per day
Diameter & Length:Accept customization
PP filter has high filtration efficiency, low pressure loss , stable filtration efficiency, long life, low cost filter , safety, adaptability.
Finish-treatment: Calendering, Heat setting, Singeing



1) Low temperature resistance ( 88-120 °C)
2) Excellent resistant to hydrolysis, acids and alkalies
3) Smooth surface, more defined pore size and good air permeability
4) Lower fiber release, Lower density,High mechanical characteristics
