How is the chemical resistance of PTFE Vent Membrane - Wuxi Sinceriend New Material Technology Co., Ltd.

PTFE Vent Membrane has excellent chemical resistance, which is mainly attributed to its unique molecular structure and chemical properties, as follows:
1. Stable molecular structure
In the molecular structure of PTFE, carbon atoms and fluorine atoms form a strong C-F bond with high bond energy and strong chemical stability. Fluorine atoms have high electronegativity and tightly surround carbon atoms, forming a highly symmetrical and stable molecular structure. This structure makes PTFE molecules less likely to react with other chemicals and has strong chemical corrosion resistance.
2. Chemical inertness
PTFE has extremely low surface energy and chemical activity, and hardly reacts with any chemical substances. Except for the possibility of reacting with a few strong oxidants such as molten alkali metals and chlorine trifluoride under high temperature and pressure, it has good tolerance to most acids, alkalis, salts, organic solvents, etc. Whether it is a strong acid such as sulfuric acid, hydrochloric acid, nitric acid, or a strong alkali such as sodium hydroxide, potassium hydroxide, or even a highly corrosive aqua regia, Ptfe Vent Membrane can remain stable and will not be corroded or dissolved.
3. Obvious application advantages
Due to the excellent chemical resistance of Ptfe Vent Membrane, it is widely used in many harsh chemical environments. In the chemical, electronic, pharmaceutical and other industries, it is often necessary to contact various chemicals. Ptfe Vent Membrane can be used for ventilation protection of equipment, which can not only ensure gas exchange inside and outside the equipment, but also effectively prevent chemical corrosion, protect the internal components of the equipment from damage, and extend the service life of the equipment. At the same time, in some occasions where chemical filtration or separation is required, Ptfe Vent Membrane can also rely on its chemical resistance to play a stable role and ensure the effect of filtration or separation.
