Teflon is one of the best corrosion-resistant materials in the world today, so it is known as the “Plastic King”. It can be used for a long time in any kind of chemical medium, and its production solves many problems in the fields of chemical industry, petroleum, pharmaceuticals and so on. PTFE sealing parts, gaskets and gaskets. PTFE sealing parts, gaskets and sealing gaskets are made by molding with suspension polymer resin. Teflon is chemically resistant and temperature resistant compared to other plastics. It has been widely used as a sealing material and a filling material.

Polytetrafluoroethylene is a polymer of tetrafluoroethylene. The English abbreviation is PTFE. The trade name is "teflon" (teflon). Known as the "king of plastic". Polytetrafluoroethylene is widely used in various applications requiring acid and alkali resistance and organic solvents. It is not toxic to humans, but one of the raw materials used in the production process, perfluorooctanoic acid (PFOA), is considered to be carcinogenic.

(Teflon or PTFE), commonly known as "Plastic King", Chinese trade names "Teflon", "Teflon", "Teflon", "Teflon" and so on. It is a polymer compound obtained by polymerizing tetrafluoroethylene, and has excellent chemical stability, corrosion resistance, airtightness, high lubrication and non-stickiness, electrical insulation and good aging resistance. It can work for a long time at a temperature of +250 ° C to -180 ° C. In addition to molten metal sodium and liquid fluorine, it can withstand all other chemicals and does not change in aqua regia.

Used as engineering plastics, it can be made into PTFE tubes, rods, strips, plates, films, etc. Generally used in corrosion-resistant pipes, containers, pumps, valves, and radar, high-frequency communication equipment, radio equipment, etc. with high performance requirements. In 2002, Donghao Polytetrafluoroethylene Products Co., Ltd., a subsidiary of Tianjin Donghao Hose Technology Co., Ltd., took the lead in introducing advanced technology equipment from Japan and successfully developed and produced hoses, PTFE spiral hoses and PTFE steam soft. Domestic advanced products such as pipes and PTFE high-pressure hoses.

The dispersion can be used as an insulating immersion liquid for various materials and an anticorrosive layer for metal, glass, and ceramic surfaces. Various PTFE rings, polytetrafluoroethylene gaskets, and PTFE packings are widely used for sealing various types of anti-corrosion pipe flanges. In addition, it can also be used for spinning, fiber - fluorocarbon (foreign trade name is Teflon).

At present, various types of PTFE products have played a pivotal role in the national economy such as chemical, machinery, electronics, electrical appliances, military, aerospace, environmental protection and bridges.

(PTFE) use conditions industry chemical, petrochemical, refining, chlor-alkali, acid, phosphate, pharmaceutical, pesticide, chemical fiber, dyeing, coking, gas, organic synthesis, non-ferrous smelting, steel, atomic energy and high-purity products (such as ionic membrane Electrolytic), the transportation and operation of viscous materials, and the processing and production departments of food and beverages with strict requirements for hygiene.

Medium Hydrofluoric acid, phosphoric acid, sulfuric acid, nitric acid, hydrochloric acid, various organic acids, organic solvents, strong oxidants and various other highly corrosive chemical media.

Temperature -20 ~ 250 ° C, allowing quenching and rapid heating, or alternating hot and cold operation.

聚四氟乙烯常识

聚四氟乙烯是当今世界上耐腐蚀性能最 佳材质之一，因此得"塑胶王"之美称。它能在任何种类化学介质长期使用，它的产生解决了我国化工、石油、制药等领域的许多问题。聚四氟乙烯密闭件、垫圈、垫片. 聚四氟乙烯密闭件、垫片、密闭垫圈是选用悬浮聚合树脂模塑加工制成。聚四氟乙烯与其他塑胶相比具有耐化学腐蚀与耐温优异的特点，它已被广泛地应用作为密闭材质和填充材质。

聚四氟乙烯是四氟乙烯的聚合物。英文缩写为PTFE。商品名为"特氟隆"（teflon)。被美誉为"塑胶之王"。 聚四氟乙烯广泛应用于各种需要抗酸碱和有机溶剂的,它本身对人没有 毒性，但是在生产过程中使用的原料之一全氟辛酸铵(PFOA)被认为可能具有致癌作用。

（Teflon或PTFE）,俗称"塑胶王"，中文商品名"铁氟龙"、"特氟龙"、"特富隆"、"泰氟龙"等。它是由四氟乙烯经聚合而成的高分子化合物，具有优良的化学稳定性、耐腐蚀性、密闭性、高润滑不粘性、电绝缘性和良好的抗老化耐力。能在+250℃至-180℃的温度下长期工作，除熔融金属钠和液氟外，能耐其它一切化学药品，在王水中煮沸也不起变化。

用作工程塑胶，可制成聚四氟乙烯管、棒、带、板、薄膜等。一般应用于性能要求较高的耐腐蚀的管道、容器、泵、阀以及制雷达、高频通讯器材、无线电器材等。2002年由天津市东浩软管科技有限公司下属的东浩聚四氟乙烯制品有限公司率先引进日本先进技术设备成功研制生产了软管、聚四氟乙烯螺旋软管、聚四氟乙烯蒸汽软管、聚四氟乙烯高压软管等国内先进产品。

分散液可用作各种材质的绝缘浸渍液和金属、玻璃、陶器表面的防腐图层等。各种聚四氟圈、聚四氟垫片、聚四氟盘根等广泛用于各类防腐管道法兰密闭。此外，也可以用于抽丝，纤维--氟纶（国外商品名为特氟纶）。

目前，各类聚四氟乙烯制品已在化工、机械、电子、电器、军工、航天、环保和桥梁等国民经济领域中起到了举足轻重的作用。
