Polyamide (PI P84) needle felt
Our company uses high-quality fiber raw materials and advanced needle punching technology and equipment to produce various polyamide needle punched felt with high dust content and good breathability. PI/P84 media has good chemical resistance, but can be threatened under high alkaline and humid conditions. The trend of oxidation through O2 or NO2 at high temperatures is limited.
Loose roll: Customize weight, thickness, density, roll width, and roll length according to your requirements.

Features and advantages:
High temperature needle punched felt
Non flammable and high-temperature resistant organic fibers
Extending Bag Life in Low pH Applications
Helps to reduce the pressure difference of bag filters
It can prevent acid corrosion in high-temperature applications and is resistant to bending wear (unlike glass fiber).
It is not recommended to use high concentrations of alkali at high temperatures.
Continuous working temperature 240 ° C
