Fluorine-free PTFE membrane is a high-performance membrane material with many excellent properties. It has excellent UV resistance, which can effectively resist the attack of ultraviolet rays, thus maintaining its physical properties. Fluorine-free PTFE membrane also has excellent chemical properties, which can be used in various chemical environments, and also has excellent high temperature resistance and corrosion resistance. In addition, the fluorine-free PTFE membrane has a low coefficient of friction and self-lubrication, which can be used under various friction conditions, while also having high electrical insulation properties and flame retardant properties. Due to these excellent properties, fluorine-free PTFE membranes are widely used in various fields, such as chemical reaction engineering, environmental protection, food packaging, etc.
Benefits include: Excellent chemical stability: Fluorine-free PTFE membranes have excellent corrosion resistance and are resistant to most chemicals, including strong acids, alkalis, and organic solvents.
Excellent resistance to high and low temperatures: Fluorine-free PTFE membranes are able to maintain their physical and mechanical properties in both high and low temperature environments, making them suitable for applications under various extreme temperature conditions.
Good electrical properties: Fluorine-free PTFE membrane has excellent insulation properties and dielectric properties, and is suitable for insulating materials and capacitor dielectrics in the electronic and electrical industries.
Low coefficient of friction and self-lubrication: Fluorine-free PTFE membranes have a low coefficient of friction and self-lubrication, making them ideal materials for bearings, seals and plain bearings.
Easy to process: Fluorine-free PTFE membranes are easy to process into parts of various shapes and sizes, and can be bonded to metal or other materials.
Disadvantages include: Poor adhesion: Due to the low surface energy of fluorine-free PTFE membranes, it is difficult to bond with other materials, and special adhesives or treatment methods are required to achieve good bonding results.
Poor abrasion resistance: Although fluorine-free PTFE membranes are self-lubricating, they have relatively poor abrasion resistance and are susceptible to mechanical wear or scratches.
*Higher: Compared to some conventional materials, fluorine-free PTFE membranes have a higher **, which may increase the cost of some application areas.
The above are the advantages and disadvantages of fluorine-free PTFE membranes, which need to be comprehensively considered according to the actual needs and application environment.
