1. Teflon telescopic tube.
Teflon telescopic tube also known as Teflon spring tube. The first time I heard about the telescopic tube, I was confused. I didn't know there was such an individual name for the spring tube. When it comes to spring tubes, you may be more conceptual.
Teflon spring tube, as the name suggests, looks like a spring, but the material is different, there are PTFE, FEP, PFA and other materials of the spring tube.
Teflon spring tube is a spring tube made of Teflon material, which is often used in heat exchangers and steam tubes. Various frequency wire and cable sheaths, slot insulation tubes; Various corrosive media (harsh solvents) delivery pipelines; Liquid crystal manufacturing device; High purity reagent delivery pipe; Insulation tube for oil motor; Tubes for single-ended luminous single-core optical fibers, tubes for air conditioning wiring harness components, etc.
performance of spring tube:
1. High and low temperature resistance:-196-260 ℃ high temperature, strength twice as large as F4. Non-stickiness, water and oil, no fouling inside and outside the pipe wall, no flow. Electrical reliability, high insulation 601HZ-60MH high and low temperature dielectric often stick is 2.1. Even if the surface is damaged by diving, it will not be conductive. Track volume resistance> 10180M surface resistance> 2*10130M; Arc resistance> 165 seconds without leakage.

2, corrosion resistance: only high temperature element fluorine, alkali metal and its role, all other concentrated, dilute inorganic organic acids, alkali, ester has no effect; Low water absorption: low absorption rate <0. 01%;
3. Non-combustibility: it will not burn in the air (oxygen index> 95V0L), which is non-toxic and physiologically inert;
4. High transparency: the lowest refractive index of light in all plastics; weather resistance: can be exposed to ozone and sunlight for a long time;
5. Easy secondary processing: self-sealing, self-welding, flanging and making of disc-to-pipe. Kan
2. ptfe extrusion tube
Polytetrafluoroethylene (PTFE extrusion tube) has excellent chemical stability, can withstand all strong acids, strong bases, strong oxidants, and does not act with various organic solvents. PTFE has a wide range of temperature, and can be applied to -180 ℃ ~ 250 ℃ for a long time under normal pressure. After being treated at 250 ℃ for 1000h, its mechanical properties change very little. PTFE has a very low friction coefficient, is a good antifriction, self-lubricating material, its static friction coefficient is less than the dynamic friction coefficient, so used to make the bearing has the advantages of small starting resistance, smooth operation.
Because PTFE is non-polar, heat-resistant and non-absorbent, it is also an excellent electrical insulating material. Also has excellent aging resistance, non-sticky and non-flammable.
PTFE made of bars, pipes, films, bearings, gaskets, valves and other profiles and parts, widely used in machinery, chemical, aviation, electrical and electronics, national defense industry, cutting-edge technology, medical and health and electrical insulation and other fields.
