Owing to its broad use, PTFE is called "the king of plastics". It is a sort of synthetic polymer material. The skeleton of PTFE is carbon atom. And the fluorine atom is evenly dispersed round the carbon atom and forms the compact protective screen. Therefore, PTFE Rods has the quite excellent physical mechanical property. It may not only resist the strong acid, strong alkali and strong oxidant but also can carry heat. To some degree, its property surpasses the property of glass, ceramic, stainless steel and gold. Its working temperature ranges from100 to 100 Celsius degrees. Its working pressure is 10 MPa. What is more, PTFE doesn't easily become older or is not easily burned. The home of the water absorption is almost identical to zero. In the normal situation, the PTFE has no harm to people's health, but in the course of creation some raw materials are regarded as the carcinogenic substance. With the creation of PTFE, it is of great significance for the industry, because it solves a lot of problems in the chemical sector, oil business and pharmacy industry. It has been widely used as the main sealing material and filling material.
As a sort of sealing material, Teflon is employed by various ways. The good corrosion resistance, constant physical property and temperature endurance make lead to its excellent sealability. Consequently, it is really relevant in the following businesses, for example petroleum, chemical, electrical and steel. The pertinent media are also in a wide variety, including water, oil, acid liquid and other chemical liquid. PTFE gasket is among the conventional applications for the PTFE material. As its title implies, the so-called PTFE gasket is a type of gasket which is made through cutting the PTFE Rods, conduit or plate. The primary substance is Teflon and so this gasket naturally inherits all features of Teflon. It includes level gasket, V-gasket, piston ring and ball valve gasket. The PTFE gasket is characterized by the following characteristics, for example corrosion resistance, aging resistance and non conductivity.
Next, PTFE is also a type of filtering material. As a brand new material, the Teflon might be compounded with other cloth. Then they can produce the filtering bag or the water proof sport suits. At the similar time, this compound may be used to filter different solvents or gases within the pharmacy sector.
Third, PTFE is also the ideal material for bearing. The bearing made of PTFE may be utilized in the paper making or textile industries. In Any Case, this bearing is acceptable to work under the high temperature or high-pressure conditions.
Common Applications of PTFE
There are numerous ways PTFE can be utilized. Here are a few of the most frequent industries that use this kind of material:
-- Pharmaceuticals - PTFE coatings are important in the pharmaceutical industry because they supply over braid seals and strength and ease when cleaning and purging the system. The pharmaceutical industry has quite high standards for all materials used within it, and PTFE meets or exceeds these high standards.
-- Automotive - Many vehicles use PTFE parts, especially in air brake systems in which constructions made of over-braided hoses are needed. Teflon can resist some extremely high temperatures, which makes it perfect for use in the outside edge of air compressors. Also PTFE works to reduce deposits of carbon particles, therefore it is extremely useful in all types of automotive applications.
-- Cryogenic - Along with being able to withstand extremely high temperatures, additionally, it may withstand the really low temperatures used within the cryogenics industry. This material is perfect for use in hydraulic hoses, piston rings, fuel lines, or liquid air systems.
-- Chemical industry - You'll often find PTFE in hoses that are used to transfer substances, connectors, and lines for merchandise interchange. Refrigeration systems and steam lines also include PTFE. The material normally replaces corrugated, stainless steel hoses get more info.
