ptfe filter bags

  • Our imported high tech fully automatic production line, which guaranteed PTFE filter bag production efficiency, felt quality and lowered product cost
  • We have also equipped with PTFE fiber production line, and PTFE needle pucnhed felt production, together with PTFE scrim production machine. Therefore, from all the production process, we can control the PTFE filter bags quality well and control the cost in the same way
  • Boing filter is one of the very few factories in China that we can produce PTFE staple fibers
  • Welcome friends to visit our PTFE fiber and PTFE filter bags production workshop

PTFE Filter Bag Surface Treatment

There are 2 kinds of treatment : "PTFE film", also called PTFE membrane and "PTFE dipping"

PTFE film/membrane: Improve filtration precision: ≤5gsm/Nm3, but lower the filtration efficiency; and a substantial increase in acid-base resistance property

PTFE dipping: Improve filtration precision: ≤25gsm/Nm3, does not lower the filtration efficiency; and a small increase in acid-base resistance property

PTFE Filter Bag Features

1. Excellent temperature resistance: up to 260℃ (572℉)

2. Extremely long working life. Service life can reach 6 years at the temperature 66℃~240℃ and normal working conditions.

3. Excellent performance of anti-acid and anti-alkali resistance

4. Excellent filter efficiency 

5. Good performances of hydrolysis stability and flame retardant

6. Suitable using on various power plant boiler and waste incineration boiler. The weakness is poor folding property and higher price.
