Brief introduction of PTFE gasket process and bulky sheet
PTFE as a sealing material has many applications. Because of its high corrosion resistance, stable physical properties, high and low temperature resistance, it has good sealing performance and is widely used in petroleum, chemical, pharmaceutical, electric power and steel industries. Suitable media include water, oil, acid solution, alkali solution and almost all chemical ingredients.

A brief introduction to the operating conditions and characteristics of modified PTFE gaskets
Modified PTFE gasket is a good gasket sealing material. It is a polymer compound polymerized from tetrafluoroethylene. It can be used for a long time in any kind of chemical medium. It is the lowest friction coefficient in solid materials. It is also the smallest surface tension in solid materials. It does not adhere to any substances, especially stable chemical corrosion resistance. It is effectively applied and solves many problems in the fields of chemical, petroleum, and pharmaceutical in my country.

A brief introduction to the performance, application and superiority of PTFE tube
PTFE pipe is the use of high-quality plunger extrusion pipe, the use of special processing technology, so that the steel pipe and plastic pipe closely combined, can withstand positive pressure 1.6Mpa, negative pressure: 77Kpa; can be in -60 ℃ ~ 260 ℃ within the normal use, with reliable and excellent corrosion resistance. Transporting strong corrosive gases and liquids at high temperatures, which cannot be replaced by other pipelines.

A brief introduction to the production process and application of polytetrafluoroethylene microporous membrane
Dankai PTFE film is mainly divided into two kinds: microporous membrane and turning membrane. The biggest difference between the two is that the microporous film is breathable, which is produced by two-way stretching; the turning film is cut out by a lathe, and it is not breathable.

Brief Introduction of Polytetrafluoroethylene Forming Process
The molding of expanded polytetrafluoroethylene is divided into two stages. In the first stage, PTFE bulk resin is mixed with lubricating aid in a certain proportion. After placing for a certain period of time, the preform is preformed, and then the paste is extruded into a longitudinally arranged fibrous preform and dried to remove the auxiliary agent. In the second stage, high-speed stretching is carried out at a temperature lower than the melting point of polytetrafluoroethylene, and then the semi-finished polytetrafluoroethylene in the stretched state is heat-set at a temperature higher than the melting point to obtain expanded polytetrafluoroethylene products.

A brief introduction to the mechanical and chemical properties of polytetrafluoroethylene
Polytetrafluoroethylene [PTFE,F4] is one of the best corrosion resistance materials in the world, so it is known as the "plastic king. It can be used in any kind of chemical medium for a long time, and its production has solved many problems in the fields of chemical industry, petroleum, pharmacy and so on.
