High-Temperature Chemical Fiber Needle Punched Filter Material
What Is High Temperature Resistant Chemical Fiber Needle Punched Filter Material?
A: High temperature resistant chemical fiber needle punched filter material is a specialized filtration material made of high-performance fibers (PPS, Metamax, P84, PTFE) via three-dimensional needle punching. It is engineered for harsh, high-temperature flue gas environments, offering exceptional chemical stability, temperature resistance, and mechanical strength, suitable for industries like coal-fired power, waste incineration, and steel manufacturing.
Performance and Characteristics
Core Advantages
PPS Series Chemical Fiber Filter Material
Material & Performance: Made of PPS (polyphenylene sulfide) fiber, usable long-term below 190℃. It features excellent chemical stability and strength retention, particularly effective in high-sulfur flue gas environments (e.g., coal-fired boilers, power plants, waste incineration).
PTFE Series Chemical Fiber Filter Material
Material & Performance: Constructed from PTFE (polytetrafluoroethylene) fiber, a macromolecular linear structure with extreme stability, wear resistance, and outstanding temperature resistance. Widely applied in harsh flue gas filtration scenarios like steel, power, and waste incineration.
Metamax & P84 Series
Metamax: Offers high breaking strength (≥1100N/5×20cm radial) and temperature resistance (continuous 204℃, 瞬间 240℃).
P84: Balances strength and temperature performance, suitable for moderate high-temperature filtration needs.
Function & Application
It is widely used in flue gas filtration for industries with high-temperature and corrosive conditions:
PPS: Coal-fired power plants, waste incineration with high sulfur content.
PTFE: Steel mills, power plants, and other harsh flue gas environments.
Metamax/P84: Applications requiring enhanced strength or moderate temperature resistance.
