With the development of science and technology, some filter materials are emerging in endlessly. There are many filter materials on the market now, Teflon microporous membrane manufacturer is one of them.
PTFE film is mainly divided into two types: microporous film and turning film. The difference between the two is that the microporous membrane is breathable and is produced by two-way stretching; the turned membrane is made by lathe cutting and is not breathable. PTFE turning film is made from ultra-fine, pure resin and is molded into a stress-free/void-free blank. It is cut using an advanced computer-controlled lathe. It has high tensile strength and insulation, and can be used in a wide temperature range. (-180℃~+250℃), radiation resistance, aging resistance, and good hydrophilicity. The contact angle between the polytetrafluoroethylene film and water is very small, and it is almost not contaminated by any liquid. At the same time, PTFE turning films can be divided into directional films, semi-directional films, and non-directional films. The PTFE turning films obtained by calendering are directional films and semi-directional films. Turned films without calendering are non-directional films. Film, the one with higher degree of calendering is directional film, and the calendering cost of semi-directional film is lower than that of directional film.
Teflon microporous membrane manufacturerPolytetrafluoroethylene PTFE microporous membrane is made of polytetrafluoroethylene resin particles. A microporous film formed after stretching and hot spot molding at a temperature below the melting point. It is a flexible and elastic microporous material with uniform pore size distribution and is breathable and impermeable.
It is Teflon microporous membrane manufacturer, which is generally divided into the following types : Air filtration membrane, which can be used for atmospheric dust removal, air purification, etc., and is the filter material for various vacuum cleaners, air filters, and purification equipment; waterproof and moisture-permeable microporous membrane, good windproof and warmth retention, widely used in medical, fire-fighting, anti-virus, and water immersion Clothing and outdoor sleeping bags, tents, etc.; PTFE bubble-point membrane, which has small pore size, a pore-making range of about 0.1-1μm, uniform distribution, and large porosity. It is widely used in pharmaceuticals, biochemistry, microelectronics, and laboratories. Consumables and other fields. Interested parties can enter the store for consultation and purchase!
