●Medium-temperature Metamax needle felt product introduction
Medium-temperature Metamax needle felt is a high-performance medium-temperature filter material made of aramid fiber, commonly known as Metamax needle felt in the industry. Its core material is aramid 1313, which has good high temperature resistance, oxidation resistance and mechanical strength, and is widely used in industrial dust removal systems under 150℃~200℃ working conditions.
●Main parameters
Project parameter range
Material 100% aramid 1313 (Metamax)
Weight 500~550g/m²
Thickness 1.8~2.2mm
Continuous temperature resistance 190℃
Instantaneous temperature resistance 204~210℃
Surface treatment singeing, calendering, lamination, water and oil repellency, etc.
Optional functions anti-static, acid and alkali resistance, PTFE lamination, etc.
●Product advantages of medium temperature Metamax needle felt
1. Excellent temperature resistance
Long-term stable operation at 190℃, short-term temperature resistance up to 210℃, suitable for high temperature fluctuation occasions, such as kiln and boiler flue gas treatment.
2. Good mechanical strength and dimensional stability
Aramid fiber has extremely high tensile strength and wear resistance, and needle felt is not easily damaged or shrunk under strong pulse cleaning.
3. Excellent chemical corrosion resistance
Can resist most weak acids, weak alkalis and oxidizing flue gases, suitable for sulfur-containing fuels or acidic gas conditions.
4. High filtration efficiency
Microfiber structure + surface treatment (such as PTFE coating) can achieve ultra-high filtration accuracy, and dust emission is stable at <10mg/Nm³.
5. Strong adaptability and long service life
Not easy to age due to condensation or fluctuations in working conditions, the normal service life is 2~4 years, and it is more durable than ordinary medium-temperature filter materials.
●Typical application areas
Cement plant clinker cooling, vertical kiln, kiln tail dust removal
Asphalt mixing station dust removal system
Garbage incinerator central control dust removal
Chemical plant high-temperature exhaust gas filtration
Power plant boiler, steel plant sintering machine dust removal
●Why choose Metamax material?
Metamax is one of the trade names of aramid 1313 (such as DuPont Nomex, Kanglong, Metas all belong to this category). Compared with other medium-temperature materials such as PPS and acrylic, it has better temperature resistance and mechanical stability, and is suitable for working conditions with high requirements and strict emission standards.
