PTFE bubble point film is the most commonly used, latest and most representative material product in the membrane material industry. It combines the efforts of PTFE bubble point film manufacturers. Let us learn about this kind of film together today. Material.
Polytetrafluoroethylene microfiltration membrane is an expanded polytetrafluoroethylene (e-PTFE?) microporous filter membrane compounded on various substrates (such as polyester felt, PET, PP non-woven fabrics) using a special process wait).
The coated filter material not only maintains the inherent high chemical stability, low friction coefficient, high and low temperature resistance, anti-aging, etc. of polytetrafluoroethylene, but can resist tiny particles, and is unmatched by ordinary coated filter materials. Breathability, waterproofness and other properties.
A membrane with screening function made by ptfe bubble point membrane manufacturer.
Polytetrafluoroethylene is a linear polymer. Due to its high polymer chain and low cohesive energy, there is no suitable solvent to prepare the casting liquid. It can only be sintered, cut, stretched or extruded to form a film. .
The intergranular region forms pores and becomes a microfiltration membrane.
If combined with polyethylene mesh, it can be made into a high-strength microfiltration membrane.
It has good chemical stability, is resistant to strong acids, strong alkali, strong oxidants and organic solvents, and can be used at high temperatures.
However, the membrane is highly hydrophobic, does not absorb water, has poor creep resistance and low bending strength, so care should be taken when using it.
Suzhou New Material Technology Co., Ltd. is a PTFE bubble point film manufacturer focusing on the R&D and production of PTFE composite materials. After years of painstaking research and R&D, the company not only has strong R&D strength, complete testing methods and domestic Advanced experimental equipment has also attracted a large number of outstanding technical talents.
