Product description of polytetrafluoroethylene board:

Tetrafluoroethylene board (also known as PTFE board, PTFE board stair pad, PTFE board, PTFE board) is divided into two types: compression molding and turning. Compression molding board is made by molding polytetrafluoroethylene resin at room temperature, and then sintering and cooling it. Polytetrafluoroethylene turning plate is made of polytetrafluoroethylene resin through pressing, sintering, and rotary cutting. Its products are widely used in polytetrafluoroethylene (PTFE) sheets, which have excellent comprehensive properties such as high and low temperature resistance (-192 ℃ -260 ℃), corrosion resistance (strong acid, strong alkali, aqua regia, etc.), weather resistance, high insulation, high lubrication, non adhesion, and harmlessness. Polytetrafluoroethylene board is suitable for supporting stairs with a 5mm thickness at temperatures ranging from -180 ℃ to+250 ℃. It is used as a lining, sealing, and lubricating material for working in various corrosive media, and is also made into electrical insulation components for use at various frequencies. Polytetrafluoroethylene board is mainly used as an insulation material for electrical appliances and as a lining, supporting slider, track seal, and lubricating material for contact with corrosive media. The 5mm polytetrafluoroethylene board is widely used as an anti-corrosion lining material for chemical and dye industry containers, storage tanks, reaction tower kettles, and large pipelines; Mechanical, construction, transportation bridge sliders, guide rails; Anti sticking materials for printing and dyeing, light industry, textile industry, etc. Has * compliant forming ability, without the need for special increase in compression force, greatly extending the service life of the flange. The radiation resistance of polytetrafluoroethylene is poor (104 rad), and it degrades after being exposed to high-energy radiation, resulting in a significant decrease in the electrical and mechanical properties of the polymer.

It is not corroded by known acids, alkalis, salts and oxidants, and even aqua regia can do nothing about it, so it is named Plastic King. Except molten metal sodium and liquid fluorine, it is resistant to all other chemicals, and is widely used in all kinds of applications that require resistance to acids, alkalis and organic solvents, sealing, high lubrication, non adhesion, electrical insulation, good anti-aging resistance, and excellent temperature resistance (it can work * at a temperature of+250 ℃ to -180 ℃). Polytetrafluoroethylene itself is not toxic to humans, but one of the raw materials used in the production process, perfluorooctanoic acid ammonium (PFOA), is believed to have carcinogenic effects.

PTFE gasket is a type of hard, tightly compressed, and easily formed three-dimensional space that can be embedded into micro cracks and damaged areas for repairing and plugging leaks. It is particularly effective in acid resistant, alkali resistant, corrosion-resistant, non-metallic facilities, and large-diameter vessels, and can effectively protect the installation and connection of brittle materials. Moreover, it can compensate and balance errors caused by defects, mechanical processing, rigid deformation, installation misalignment, etc., balance uneven pre tightening force, and effectively solve leakage problems of various facilities under complex conditions. Replace quartz glassware for ultra pure chemical analysis and storage of various acids and bases in industries such as atomic energy and semiconductors.

It is composed of soft pads such as asbestos rubber sheets or asbestos free sheets, and PTFE coated thin sheets. The V-shaped (cut type) PTFE clamping gasket is mechanically turned from PTFE sheets, and the U-shaped (folded type) PTFE clamping gasket is made by heating and bonding PTFE tape edges. It has excellent corrosion resistance and good compression rebound rate, and is widely used for sealing various strong acids, strong alkalis, strong oxidants, and non polluting media. PTFE gaskets have a low thermal conductivity and a high coefficient of linear expansion, which can cause cold flow under load. They are suitable for use on uneven surfaces, full surfaces, and slot flanges at medium temperature and low pressure. Adding different fillers such as glass fiber, graphite, molybdenum disulfide, bronze powder, etc. can improve the performance of PTFE gaskets. Usually applicable to medium and low voltage areas.

After being exposed to radiation from sources such as electron accelerators and other radiation sources, these materials will have a "memory effect", and the expanded, cooled and shaped materials can shrink back to their original shape after being heated. The memory performance of heat shrink materials can be used to make heat shrink pipes, films, and shaped materials. The main characteristic is that the heat shrink coating is applied to the outer surface of the object, which can provide insulation, moisture resistance, sealing, protection, and continuity. The radial shrinkage rate of the shrink material can reach 50% -80%. In short, the thermal shrinkage behavior of polymers is an artificial behavior, which is the crystallization of human technological development and wisdom, while the thermal shrinkage and cold expansion behavior of small molecules is a unique creation of nature. Various special-shaped materials and parts made of polytetrafluoroethylene, such as rods, pipes, films, bearings, gaskets, valves, etc., are widely used in fields such as machinery, chemical industry, aviation, electrical and electronics, industry, technology, health, and electrical insulation. In our daily lives, there are many materials and solvents that are resistant to acid and alkali, and polytetrafluoroethylene (PTFE) also has the same function. It can not only withstand high temperatures, but also has a relatively low friction coefficient and can be used as a lubrication operation. So, what are the methods for surface treatment of PTFE? Let me tell you about it. It is the high-temperature melting method, which involves causing some morphological changes on the surface of PTFE at high temperatures, embedding some high surface energy and easy to bond substances. After cooling, a modified layer with bonding substances will be formed on the surface of PTFE. It should be noted that the bonding layer method is more suitable for outdoor use, but it is not easy to maintain its shape. PTFE film is often used in economic fields such as chemical, mechanical, electronic, electrical, and aerospace industries. You should know that PTFE film is a product with many advantages, It can bring a lot of help to our lives, but there are also some disadvantages. So, what are the advantages of polytetrafluoroethylene? Let me tell you. Firstly, polytetrafluoroethylene film can withstand a temperature range of 250 degrees. Secondly, in addition to high temperature resistance, the low-temperature resistance of the board is also good. If the working temperature is reduced to minus 196 degrees Celsius, the product can maintain a productivity of 5%, and the mechanical toughness of the product is also considerable. In addition, the weather resistance of polytetrafluoroethylene board itself is also very good. If polytetrafluoroethylene film is used normally, its aging resistance life is relatively long. Thirdly, the disadvantage of polytetrafluoroethylene film is that... There is no viscous flow state and insufficient filling flowability, making it difficult to process and shape, Products cannot be manufactured using the molding method of general thermoplastic materials. Currently, only processing methods such as compression molding sintering and extrusion sintering can be used to manufacture products with simple shapes Polytetrafluoroethylene is used. Including artificial blood vessels and patches for soft tissue regeneration, as well as surgical sutures for blood vessels, heart, general surgery, and plastic surgery

A polymer compound formed by the polymerization of tetrafluoroethylene, with a simple structural formula of - [- CF2-CF2-] n -, has excellent chemical stability and corrosion resistance. Polytetrafluoroethylene, abbreviated as PTFE or F4, is one of the corrosion-resistant materials today. "Plastic King" is the common name for polytetrafluoroethylene, which is a plastic with good corrosion resistance. It is not corroded by known acids, alkalis, salts and oxidants, and even aqua regia can do nothing about it, so it is named Plastic King. Except molten metal sodium and liquid fluorine, it is resistant to all other chemicals, and is widely used in all kinds of applications that require resistance to acids, alkalis and organic solvents, sealing, high lubrication, non adhesion, electrical insulation, good anti-aging resistance, and excellent temperature resistance (it can work * at a temperature of+250 ℃ to -180 ℃).
