Teflon plate (also called teflon plate, Teflon plate, Teflon plate) is divided into two kinds of molding and turning. The molding plate is made of teflon resin by molding at room temperature, and then sintered and cooled. Teflon turning board is made of teflon resin by pressing, sintering and rotary cutting. Its products are widely used, with extremely superior comprehensive performance: high and low temperature resistance (-192℃-260℃), corrosion resistance (strong acid, strong alkali, aqua aureus, etc.), weather resistance, high insulation, high lubrication, no adhesion, damage and other excellent characteristics. Polytetrafluoroethylene (English abbreviation Teflon or [PTFE,F4]), known as a good reputation/commonly known as the "plastic king", Chinese trade name "teflon", "Teflon" (teflon), "Teflon", "Teflon", "Teflon", "Teflon" and "Teflon".
It is made of tetrafluoroethylene by polymerization of polymer compounds, its structure simple formula is -[-CF2-CF2-]n-, has excellent chemical stability, corrosion resistance (PTFE for short or F4, is one of the world's corrosion resistant materials, "plastic king" is commonly known as tetrafluoroethylene, it is a kind of good corrosion resistance plastic. It is not subject to the known acid, base, salt, oxidant corrosion, even the royal water can do nothing to it, hence the name of the plastic king, in addition to molten metal sodium and liquid fluorine, can resist all other chemicals, Widely used in all kinds of need acid, alkali and organic solvent resistance, sealing, high lubrication non-viscosity, electrical insulation and good aging resistance, excellent temperature resistance (can work in +250℃ to -180℃ temperature for a long time). Teflon itself is not toxic to humans, but ammonium perfluorooctanoate (PFOA), one of the raw materials used in the production process, is thought to be possibly carcinogenic.
The temperature is -20 ~ 250℃ (-4 ~ +482°F), allowing sudden cooling or alternating hot and cold operation.
Pressure -0.1 ~ 6.4Mpa (Full vacuum to 64kgf/cm2) (Full vacuum to 64kgf/cm2)
Its production solves many problems in chemical, petroleum, pharmaceutical and other fields. Ptfe seals, gaskets, gaskets. Ptfe seals, sealing gaskets are made of suspension polymerization PTFE resin molding. Compared with other plastics, PTFE has the characteristics of chemical corrosion resistance. It has been widely used as sealing material and filling material.
Its complete thermal decomposition products at around 500 degrees Celsius are tetrafluoroethylene, hexafluoropropylene and octafluorocyclobutane, which at high temperatures decompose into highly corrosive fluorinated gases.
Use:
All kinds of
Ptfe Products have been in the chemical industry, machinery, electronics, electrical appliances, military, aerospace, environmental protection and Bridges in the national economy has played a pivotal role.
Tetrafluoroethylene plate is suitable for -180℃~+250℃ temperature, mainly used as electrical insulation materials and contact corrosive medium lining, support slider, rail seals and lubrication materials, rich cabinet furniture it is used in light industry, widely used in chemical, pharmaceutical, dye industry container, storage tank, reactor, large pipeline anticorrosive lining material; Aviation, military and other heavy industries; Machinery, construction, traffic bridge slider, guide rail; Printing and dyeing, light industry, textile industry, etc
Material advantages:
High temperature resistance - working temperature up to 250℃.
Low temperature resistance -- good mechanical toughness; Even if the temperature drops to -196℃, 5% elongation can be maintained.
Corrosion resistance - For most chemicals and solvents, showing inertia, strong acid and alkali resistance, water and various organic solvents.
Weather resistant - has the best aging life in plastics.
High lubrication - is the low friction coefficient of solid materials.
Non-adhesion -- is a small surface tension of solid materials, does not adhere to any substance, mechanical properties, its friction coefficient is very small, only 1/5 of polyethylene, which is an important feature of perfluorocarbon surface. And because fluorine - carbon chain molecular intermolecular force is very low, so PTFE is non-viscous.
Harm - has physiological inertia, as artificial blood vessels and organs implanted in the body for a long time without adverse reaction.
Electrical properties polytetrafluoroethylene has low dielectric constant and dielectric loss over a wide range of frequencies, and high breakdown voltage, volume resistivity and arc resistance.
Radiation resistance The radiation resistance of polytetrafluoroethylene is poor (104 rads). After being exposed to high energy radiation, the electrical and mechanical properties of the polymer are significantly decreased. The application of polytetrafluoroethylene can be compressed or extrusion processing; It can also be made into a water dispersion for coating, dipping or making fibers. Polytetrafluoroethylene in atomic energy, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textile, food and other industries are widely used as high and low temperature resistance, corrosion resistant materials, insulation materials, anti-stick coating.
Atmospheric aging resistance: radiation resistance and low permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged.
Incombustible: oxygen limit index below 90.
Acid and alkali resistance: insoluble in strong acid, strong base and organic solvent.
Oxidation resistance: Resistance to corrosion by strong oxidants.
Acid base: neutral.
The mechanical properties of teflon are soft. Has a very low surface energy.
Polytetrafluoroethylene (F4,PTFE) has a series of excellent performance: high temperature resistance - long-term use temperature 200~260 degrees, low temperature resistance - -100 degrees is still soft; Corrosion resistance -- resistance to aqua regia and all organic solvents; Weather resistance -- excellent aging life in plastics; High lubrication -- small friction coefficient of plastic (0.04); Non-viscous -- has a solid material
Low surface tension without adhesion to any substance; Harm - has physiological inertia; Excellent electrical properties, is the ideal C class insulation material.
