What is the temperature range of 1. Teflon
The temperature resistance of Teflon is the use requirement that many people need to know. For high temperature resistance, Teflon can withstand 260 degrees all the time and reach 400 degrees in an instant.
Teflon has high temperature resistance and low temperature resistance. Teflon can reach -190 degrees when used for a long time, but it expands with heat and shrinks with cold. Generally, the safe and effective limit temperature is about -70 degrees.
Teflon is a special plastic with high temperature resistance, wear resistance, self-lubrication (extremely low friction coefficient) and chemical characteristics. It is a special plastic with corrosion resistance, strong acid and alkali resistance, and can withstand the effects of all strong acids (including aqua regia), strong oxidants, reducing agents and various organic solvents except molten alkali metals, fluorinated media and sodium hydroxide above 300 ℃. The chemical name is polytetrafluoroethylene (PTFE).
Teflon is a registered trademark used by DuPont on a range of its fluoropolymer products. It was invented and manufactured in a Jackson laboratory by Dr. Roy J. Plunkett.
About 70 years ago, chemist Dr. Roy J. Plunkett invented polytetrafluoroethylene resin in DuPont's Jackson laboratory in New Jersey, USA. DuPont uses "Teflon" as the brand name for the product. Subsequently, DuPont has developed a series of products in addition to Teflon PTFE resin, including Teflon AF (amorphous fluoropolymer),Teflon FEP (fluorinated ethylene propylene resin),Teflon FFR (fluoropolymer foam resin),Teflon NXT fluoropolymer resin, Teflon PFA (perfluoroalkoxy resin) and so on.
Teflon is commonly known as "plastic king". It is a polymer compound formed by the polymerization of tetrafluoroethylene. It has excellent chemical stability and corrosion resistance (it is one of the best corrosion-resistant materials in the world today. In addition to molten metal sodium and liquid fluorine, it can withstand all other chemicals. It does not change when boiled in aqua regia, widely used in a variety of need to resist acid and alkali and organic solvents), sealing, high lubrication non-stick, electrical insulation and good anti-aging endurance, excellent temperature resistance.

How to distinguish the specifications of 2. Teflon tube
When it comes to the specifications of Teflon tubes, people who don't know how to do it really don't understand it. A person who knows how to do it is a demon. How to distinguish the specifications of Teflon tubes is simple and simple to say. Visually imagine what data a tube has. Teflon tubes have inner diameter, diameter and wall thickness. These three data can be changed according to random changes. In addition to these three data, there are metric and imperial systems.
Teflon tube specifications have regular and special specifications
Common specifications: inner diameter * outer diameter (unit: mm)
Metric: 2*4 3*5 4*6 5*7 6*8 8*10 8*12 9*12 10*12
12*14 14*16 16*18 18*20 20*22
Imperial: 1/8 inch (1.6*3.2) 1/4 inch (3.96*6.35) 3/8 inch (6.35*9.525)
1/2 inch (9.5*12.7) 3/4 inch (15.88*19.05) 1 inch (22.2*25.4)
Other producible specifications, inner diameter 0.5mm to 200mm, wall thickness 0.12mm to 3mm
Special specifications are 2.5*3.5,3.8*5.8 and so on, specific production according to customer specifications.
