 Polyester / Polypropylene Filter Felt: 

Our polyester needle punched felt has the following characters:
1. High tenacity and low elongation polyester yarn for scrim material, which enhances the breaking strength.
2. Fine fiber: makes the felt more apertures with smaller opening to improve the filtration precise.
3. High quality polyester fiber: improves acid proof, alkali proof, and hydrolysis proof ability.
4. Smoother surface: makes the filtration efficiency similar with membrane felt.
5. Small running resistance: saves energy. 

 

Benefits from the good physical and chemical characteristics of polypropylene, the PP felts are wearable, acid & alkali resistant and have good air permeability. So they are usually used in the strong acid and alkali conditions. 
Besides the dust collection application, PP needle felts are also used in the liquid filtration processes.
