PTFE needle felt also known as “Teflon”. It has a good performance in the temperature of up to 260 deg C , the instant temperature can up to 280 deg C. PTFE filter felt is a special material with good alkali and acid resistance , anti-hydrolysis , stable physical dimension so the filter bag mainly used in coal burning boiler , waste incineration ,carbon black producing ,Tio2 producing for fume treatment or dust collection , as well as some high temperature or some corrosive liquid filtration.

Note:

1. Special PTFE bag filter specification can be customized like the spun lace PTFE felt or PTFE mixed with other fiber together and so on.

2. Maximum width for PTFE filter felt: 2.2meters.

3. Both PTFE filter cloth rolls and filter bags are available at Shanghai Sffiltech.

Advantages of PTFE needle felt:

a) High temperature resistance

b) Excellent acidity resistance

c) Excellent alkalinity resistance

d) High filtration fineness

e) Best filter media in all the other filter medias.

Working principle of PTFE needle felt:

It will be sewn into PTFE filter bag for filter bag house

Working temperature is under 260 deg C.

Can be used under moisture, high harsh chemical working condition.

FAQ

Q
What is the grammage (GSM) range for this PTFE needle-punched felt filter material? What are the common specifications?
A
Our main PTFE needle-punched felt filter materials cover a grammage range of 600 to 800 GSM. For applications requiring higher strength or durability, we can also provide products with a grammage ≥850 GSM.
Q
What are the primary characteristics and advantages of PTFE needle-punched felt filter media?
A
PTFE needle-punched felt filter media offers exceptional high-temperature resistance, outstanding chemical corrosion resistance, excellent hydrolysis resistance, superior non-stick properties with a low friction coefficient, and good dimensional stability. It maintains long service life and stable filtration efficiency in high-temperature and harsh chemical environments, enabling surface filtration.
Q
What is the normal continuous operating temperature for this filter material? What is its maximum instantaneous temperature tolerance?
A
The continuous operating temperature for PTFE needle-punched felt filter material is typically ≤260°C. According to various sources, it can withstand instantaneous temperatures up to 280°C, with some grades reaching 300°C.
Q
How does PTFE filter material perform in terms of chemical resistance?
A
PTFE filter media exhibits outstanding chemical resistance, withstanding acids and alkalis across a pH range of 0-14 and remaining virtually unaffected by chemical agents.
Q
In which industries or applications is this filter media typically used?
A
PTFE needle-punched felt filter media is widely employed for dust removal in high-temperature, highly corrosive environments. Examples include high-temperature flue gas treatment in waste incineration, steel metallurgy, power generation, chemical processing, and cement industries.
