1. Teflon telescopic tube.
Teflon telescopic tube is also known as Teflon spring tube. The first time I heard the telescopic tube, I was also confused. I didn't know that the spring tube is so called. When it comes to spring tubes, everyone may be more conceptual.
Teflon spring tube, as the name suggests, looks like a spring, but the material is different. There are spring tubes made of PTFE, FEP, PFA and other materials.
Teflon spring tube is a spring tube made of Teflon material. It is often used in heat exchangers and steam tubes; various frequency wire and cable sheaths, groove insulation tubes; various corrosive media (harsh solvents) transportation Pipes; liquid crystal manufacturing equipment; high-purity reagent delivery pipes; insulated pipes for oil-replacement motors; pipes for single-end light-emitting single-core optical fibers, pipes for air-conditioning wiring harness components and other fields.
The performance of the spring tube:
1. High and low temperature resistance: -196--260℃ high temperature, twice the strength of F4. Non-sticky, fight water and oil, no fouling or flow inside and outside the pipe wall. Electrical reliability, high insulation 601HZ-60MH high and low dielectric constant viscosity is 2.1. Even if the surface is damaged by diving, it will not conduct electricity; track volume resistance> 10180M surface resistance> 2*10130M; arc resistance> 165 seconds without leakage.

2. Corrosion resistance: only elemental fluorine at high temperature, alkali metals play a role with it, and have no effect on all other concentrated and dilute inorganic organic acids, alkalis, and esters; low water absorption: low absorption rate <0.01%;
3. Non-combustibility: Will not burn in the air (oxygen index>95V0L%), non-toxic and physiologically inert;
4. High transparency: the light refractive index is the lowest among all plastics; weather resistance: it can be exposed to ozone and sunlight for a long time;
5. Ease of secondary processing: self-sealing, self-welding, flanging, and coiled pipes can be made.
2. Ptfe extrusion tube
Polytetrafluoroethylene (PTFE extruded tube) has excellent chemical stability, can withstand all strong acids, strong alkalis, strong oxidants, and does not interact with various organic solvents. PTFE has a wide operating temperature range. It can be used for a long time at -180℃~250℃ under normal pressure. After 1000h of treatment at 250℃, its mechanical properties will change little. PTFE has a very low friction factor, is a good anti-friction, self-lubricating material, its static friction coefficient is less than the dynamic friction coefficient, so it has the advantages of low starting resistance and smooth running when used to make bearings.
Because PTFE is non-polar, heat-resistant and does not absorb water, it is also an excellent electrical insulating material. It also has excellent aging resistance, non-stickiness and non-combustibility.
Various profiles and parts made of PTFE, such as bars, tubes, films, bearings, gaskets, valves, etc., are widely used in machinery, chemical industry, aviation, electrical and electronics, defense industry, cutting-edge technology, medical and health, and electrical insulation And other fields.
