PTFE Filter Membrane Material

PTFE filter membrane material is a filter material based on polytetrafluoroethylene (PTFE), which has a unique set of properties and characteristics that make it perform well in a variety of filtration applications.
​
Material and structure​

PTFE filter membrane uses polytetrafluoroethylene as raw material, through special processes (such as calendering, extrusion, bidirectional drawing, etc.) to make microporous film.

It has a fibrillar micropore structure with a porosity of more than 85% and 1.4 billion micropores per square centimeter, with pore sizes ranging from 0.02μm to 15μm.
​
Performance characteristics
​
1. High filtration efficiency
PTFE filter membrane has a very high filtration efficiency, can reach 99.99%, near zero emissions.
​
2. Resistant to chemicals
Due to its special chemical structure, PTFE filter membranes show good corrosion resistance to most chemical substances.
​
3. Breathable and watertight
PTFE filter membrane has excellent air permeability, while effectively preventing the passage of water.
​
4. Flame retardant, high temperature resistance
PTFE material itself is flame retardant and can remain stable at high temperatures.
​
5. Strong acid and alkali resistance
It has good resistance to strong acid and alkali environment.
​
6. Non-toxic
The material is safe and non-toxic and meets the requirements of environmental protection.
​
​
Application field
​
1. Industrial filtration
Mainly used in chemical industry, steel, metallurgy, carbon black, power generation, cement, waste incineration and other industrial furnace smoke filtration.
​
2. Air purification
PTFE filter membrane can be used for air purification equipment to filter small particles such as dust and bacteria in the air.
​
3. Semiconductor manufacturing
It can be used in the semiconductor manufacturing field of device filtration and cleaning, special chemical storage and transportation.
​
PTFE filter membrane material with its unique material, structure, performance characteristics and technical parameters, in many fields have shown excellent filtration performance, is an ideal filtration material.
