Three-layer and five-layer composite materials are composed of microporous membranes made of dispersed polytetrafluoroethylene resin and various substrates. Let’s take a closer look.
When the particle size of the dust is less than 1 micron, or the dust is very viscous, or the gas content is relatively high, ordinary filter materials cannot filter effectively.
The film-coated filter material made of polytetrafluoroethylene (Teflon) has extremely high filtration accuracy, smooth surface, no dust adhesion, easy cleaning, and dust will not penetrate into the interior of the filter material, achieving surface filter.
The three-layer and five-layer composite material is a composite material that uses a special process to compound the PTFE film on the surface of the clothing fabric, which is waterproof, breathable, windproof and warm.
Compared with other polymers, PTFE composites have unique advantages, but there are also some shortcomings, such as poor mechanical processing performance, large linear expansion coefficient, poor creep resistance, and easy cold flow. , poor wear resistance, difficulty in molding and secondary processing, etc., which limits its application.
At present, research on PTFE at home and abroad focuses on finding appropriate methods to modify it, improve its performance to a certain extent, and expand its application scope.
