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.
