Owing to its wide application, Liantuo Expanded PTFE is called "the king of plastics". It is a kind of synthetic polymer material. The skeleton of PTFE is carbon atom. And the fluorine atom is evenly distributed around the carbon atom and forms the compact protective screen. Therefore, PTFE has the very excellent physical mechanical property. It can not only resist the strong acid, strong alkali and strong oxidant but also can bear high temperature. To some degree, its property surpasses the property of glass, ceramic, stainless steel and gold. Its working temperature ranges from-100 to 100 Celsius degrees. Its working pressure is 10 MPa. What's more, PTFE does not easily become aged or is not easily burnt. The property of the water absorption is almost equal to zero. In the normal situation, the PTFE has no harm to people's health, but in the course of production some raw materials are regarded as the carcinogenic substance. With the invention of PTFE, it is of great significance for the industry, because it solves a lot of problems in the chemical sector, oil industry and pharmacy industry. It has been widely used as the main sealing material and filling material.
As a kind of sealing material, PTFE is applied by different ways. The good corrosion resistance, stable physical property and temperature endurance make contribute to its excellent sealability. As a result, it is very applicable in the following industries, such as oil, chemical, electric and steel. The applicable media are also in a wide range, including water, oil, acid liquid and other chemical liquid. PTFE gasket is one of the typical applications for the PTFE material. As its name implies, the so-called PTFE gasket is a kind of gasket which is made through cutting the PTFE rod, pipe or plate. The main material is PTFE and so this gasket naturally inherits all features of PTFE. It includes flat gasket, V-gasket, piston ring and ball valve gasket. The PTFE gasket is characterized by the following features, such as corrosion resistance, aging resistance and non-conductivity.
Next, PTFE is also a kind of filtering material. As a new material, the PTFE can be compounded with other fabric. Then they can produce the filtering bag or the water-proof sport suits. At the same time, this compound can be used to filter different solvents or gases in the pharmacy industry.
Third, PTFE is also the ideal material for bearing. The bearing made of PTFE can be used in the paper-making or textile industries. Besides, this bearing is suitable to work under the high-temperature or high-pressure conditions. PTFE Sheet: liantuoptfe
