Dupont Sheet Rod PTFE plate bar

Dupont®100% Virgin PTFE plastic rod and sheet DuPont uses ptfe as the brand name of the product DuPont's  trademark is mainly used in the following products: PTFE, FEP, PFA, ETFE, AF, NXT, FFR.Polytetrafluoroethene (Polytetrafluoroethene, generally referred to as "non-stick coating" or "easy to clean wok material"; is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in Polyethylene. The full English name of PTFE Polytetrafluoroetylene, referred to as PTFE, F4, etc. It is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble All solvents. At the same time, PTFE has the characteristics of high temperature resistance, its friction coefficient is very low, so it can be used for lubrication, and it has become an ideal coating for easy-to-clean woks and the inner layer of water pipes.

PTFE

Temperature -20~250°C (-4~+482°F), allowing rapid cooling and heating, or alternate operation of cooling and heating.

Pressure -0.1~6.4Mpa (Full vacuum to 64kgf/cm2) (Full vacuum to 64kgf/cm2)

It has solved many problems in chemical, petroleum, pharmaceutical and other fields. Polytetrafluoroethylene seals, gaskets, and gaskets are made of suspension polymerized polytetrafluoroethylene resin. Compared with other plastics, PTFE has the characteristics of chemical resistance, and it has been widely used as a sealing material and filling material.

Used as engineering plastics, it can be made into polytetrafluoroethylene tubes, rods, belts, plates, films, etc. The dispersion can be used as the insulating dipping solution for various materials and the anticorrosive coating on the surface of metal, glass, and ceramics. Various PTFE rings, PTFE gaskets, PTFE packings, etc. are widely used for sealing various anticorrosive pipeline flanges. In addition, it can also be used for spinning, PTFE fiber-fluorine fiber.

At present, all kinds of PTFE products have played a pivotal role in the national economic fields such as chemical industry, machinery, electronics, electrical appliances, military industry, aerospace, environmental protection and bridges.

Polytetrafluoroethylene (PTFE) use conditionsIndustry chemical industry, petrochemical, oil refining, chlor-alkali, acid production, phosphate fertilizer, pharmaceuticals, pesticides, chemical fiber, dyeing, coking, gas, organic synthesis, non-ferrous smelting, steel, atomic energy and high-purity product production (Such as ion-exchange membrane electrolysis), transportation and operation of viscous materials, food and beverage processing and production departments with strict hygiene requirements.

Characteristics of PTFE fluoropolymer

Main feature

⒈Non-sticky: Almost all substances do not adhere to the PTFE film. Very thin films also show good non-stick properties.

⒉Heat resistance: PTFE coating film has excellent heat resistance and low temperature resistance. It can withstand high temperature to 300℃ in a short time, and generally can be used continuously between 240℃~260℃. It has remarkable thermal stability. It can work at freezing temperature without embrittlement and does not melt at high temperature.

⒊Slidability: PTFE coating film has a low coefficient of friction. The friction coefficient changes when the load is sliding, but the value is only between 0.05-0.15.

⒋Moisture resistance: The surface of the PTFE coating film does not stick to water and oil, and it is not easy to stick to the solution during the production operation. If there is a small amount of dirt, it can be removed by simply wiping. Short downtime, saving working hours and improving work efficiency.

⒌Abrasion resistance: It has excellent wear resistance under high load. Under a certain load, it has the dual advantages of wear resistance and non-sticking.

⒍Corrosion resistance: PTFE is hardly corroded by chemicals and can protect parts from any kind of chemical corrosion.

Advantages of use

High temperature resistance-use working temperature up to 250 ℃.

Low temperature resistance-has good mechanical toughness; even if the temperature drops to -196 ℃, it can maintain 5% elongation.

Corrosion resistance-It is inert to most chemicals and solvents, and can withstand strong acids and alkalis, water and various organic solvents.

Weather resistance-has the best aging life among plastics.

High lubrication-is the lowest coefficient of friction among solid materials.

Non-sticking-it is the smallest surface tension among solid materials and does not stick to any substance.

Non-toxic-It is physiologically inert and has no adverse reactions as artificial blood vessels and organs implanted in the body for a long time.

Application field Material application

Polytetrafluoroethylene can be formed by compression or extrusion processing; it can also be made into water dispersion for coating, impregnation or making fibers. Polytetrafluoroethylene is widely used in industries such as nuclear energy, national defense, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textiles, metal surface treatment, pharmaceuticals, medical treatment, food, metallurgy and smelting, etc. Corrosive materials, insulating materials, anti-stick coatings, etc. make it an irreplaceable product.

PTFE has outstanding excellent comprehensive properties, high temperature resistance, corrosion resistance, non-stick, self-lubricating, excellent dielectric properties, and a very low coefficient of friction. Used as engineering plastics, it can be made into polytetrafluoroethylene tubes, rods, belts, plates, films, etc. Generally used in corrosion-resistant pipelines, containers, pumps, valves, radar, high-frequency communication equipment, and radio equipment with high performance requirements. Add any filler that can withstand the sintering temperature of polytetrafluoroethylene, and its mechanical properties can be greatly improved. At the same time, other excellent properties of PTFE are maintained. Filled varieties include glass fiber, metal, metal oxide, graphite, molybdenum disulfide, carbon fiber, Polyimide, EKONOL... etc. The wear resistance and limit PV value can be increased by 1000 times. Coating on the surface of the bullet head can increase the penetration of the bullet.
