Advantages of P84 Needle Punched Felt

  1. High Temperature Stability: P84 has excellent high temperature stability and is able to maintain its physical and chemical properties under high temperature conditions. This makes P84 filter felt ideally suited for high-temperature gas filtration applications such as cement flue gas cleaning, the metallurgical industry and coal-fired power plants.
  2. Excellent chemical resistance: P84 has good resistance to chemical attack and can therefore be used in a variety of chemical conditions, including acidic and alkaline environments.
  3. Good Filtration Efficiency: P84 filter felts are generally effective at capturing tiny particles and dust, providing excellent filtration performance. This helps improve the capture and separation of particulate matter in the air or gas.
  4. Long life and wear resistance: P84 generally have excellent wear resistance, which allows them to maintain a long service life under conditions of high flow rates and high particle loads.
  5. Low Shrinkage: The low shrinkage of P84 means it maintains its dimensional and shape stability even under high temperature conditions, ensuring continued filtration performance.
  6. Low Maintenance Cost: Due to the long life and high performance of P84 filter felt, its maintenance cost is relatively low as less replacement and repair work needs to be performed.
  7. Environmentally friendly: P84 is a synthetic fiber that generally does not contain environmentally harmful substances, so it can be used in environmentally friendly applications.
