Introduction to 1. PTFE
Polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), commonly known as "plastic king", is a polymer made by polymerizing tetrafluoroethylene as a monomer. White wax
It can be used for a long time at -180~260°C. This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all
of solvents. At the same time, PTFE has the characteristics of high temperature resistance, its coefficient of friction is very low, so it can be used for lubrication, but also become an ideal coating for the inner layer of easy-to-clean water pipes.

4. PTFE Tube FAQ
4.1 PTFE pipe how to connect
With the progress of anti-corrosion technology, anti-corrosion materials continue to introduce new ones, including polytetrafluoroethylene (PTFE) with its excellent chemical stability, high temperature resistance and chemical corrosion resistance, more and more popular
It is an ideal anti-corrosion material of choice and has become one of the indispensable and important materials today. In specific applications, due to the PTFE material itself has a high
Slip non-stick, so the connection of PTFE pipe is more troublesome. However, ptfe pipes can be connected by these two processing methods: hot air electrode welding method and manual flanging method.
Precautions for installation of 4.2 PTFE pipe
(1) Although the plastic lining is relatively soft when drilling holes, it is more troublesome to force a rigid drill bit to solve the problem. It is easy to damage the steel plastic lining pipe in the original pipeline, and the corners are not easy to be neat. It is recommended to combine the United States.
The knife is used to open the hole.
(2) In the process of drilling, the plastic residue of the lining can easily fall into the original pipeline, so more attention should be paid during the operation, otherwise it will cause the end water point to be blocked. Kan
(3) Electric (gas) welding tools cannot be used for drilling or installing branch pipes, because it will destroy the plastic lining of steel-lined PTFE pipes. The branch pipes shall be connected by special pipe fittings for grooves.

4.4 PTFE Pipe Fabrication Standard
Standard No.: QB/T 4877-2015.
This standard specifies the types, specifications, requirements, test methods, inspection rules and signs, packaging, transportation and storage of polytetrafluoroethylene pipes (PTFE pipes for short).
This standard is applicable to pipes processed with unfilled PTFE dispersion or suspension resin (including PTFE recycled resin).
4.5 PTFE tubular membrane
PTFE tubular membrane is a soft and porous hollow filter tube imported from Japan. The filter tube is made of expanded PTFE, which has excellent heat resistance and chemical stability.
Features and advantages: inert to acids, alkalis and most solvents; excellent breathability; excellent softness, easy operation; high tensile strength.
Scope of application:
1) Breathing valve (vent): one side can seep heat and sound, and the other side can block moisture and dust;
2) Liquid and gas filters;
3) Thermal insulation material, used for high temperature protection of pipelines, can form an air layer due to excellent porous properties;
4) As an exchange membrane for liquid and gas when removing gas (oxygen, ozone, etc.) and bubbles in the liquid.
4.6 Teflon pipe
Teflon (sleeve) tube is made of polytetrafluoroethylene (PTFE commonly known as Teflon, plastic king) material after extrusion sintering, drying, high temperature sintering, stereotypes and other processes made of special pipe.
Teflon is also called Teflon, Teflon, Teflon, Teflon, Teflon, Teflon, Teflon, Plastic King, English for Teflon, widely used in machinery, electronic appliances, steam
Vehicle, aerospace, chemical, computer, electric heating, military, communications and other important scientific and technological industries, such as micro-transformers.
5. PTFE Tube Application Range
5.1 medical field
PTFE is water-resistant, physiologically inert and non-sticky, so it is used in many tissue repair materials and artificial organ materials, such as artificial blood vessels, heart repair membranes, etc. And,
The biggest advantage of PTFE is that it can be sterilized by any method, and it will not be denatured by high-pressure heating or various disinfectants. Therefore, it is used in medical devices such as suture, disinfection pad, injection needle, etc.
are widely used.
5.2 Electronics and Semiconductor Industry
PTFE relies on its high purity, chemical resistance and excellent dimensional stability for the manufacture of semiconductor products for a variety of components.
5.3 Mechanical Engineering
Improve efficiency, reduce weight and energy consumption. Our innovative PTFE and bonding technologies provide superior friction control performance and critical durability for the mechanical engineering industry.
5.4 Oil and Gas
Components in the oil and gas industry are resistant to high temperatures and corrosion due to harsh chemicals, such as sulfur-containing hydrocarbons, superheated steam, carbon dioxide, methane and hydrogen sulfide
Can.
5.5 chemical industry
PTFE and PTFE fillers can make parts exhibit excellent heat resistance and their own chemical inertness are widely used in the chemical industry. PTFE is easy to install, reduces downtime,
Ensure maximum reliability.
Various profiles and parts made of PTFE, such as bars, pipes, films, bearings, gaskets, valves, etc., are widely used in machinery, chemical industry, aviation, electrical and electronics, and national defense industry.
industry, cutting-edge technology, health care and electrical insulation and other fields.
