PTFE tube working principle, characteristics, application scope
PTFE tube, scientific name PTFE tube (referred to as F4 tube, PTFE tube) is a high-quality plunger extruded tube, using special processing technology to make the steel tube and plastic tube tightly combined, and can withstand a positive pressure of 1.6Mpa , Negative pressure: 77Kpa; can be used normally in -60 ℃ ~ + 260 ℃, with reliable and excellent corrosion resistance. It can transport highly corrosive gas and liquid at high temperature, which cannot be replaced by other pipelines.
use
Wire insulation sheath, corrosive fluid medium pipeline, various electrical insulation parts used under high frequency, etc. Widely used in machinery, chemical industry, aviation, electrical and electronics, national defense industry, cutting-edge technology, medical and health care and electrical insulation and other fields.
features
PTFE 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 temperature range and can be used for a long time at -180°C~250°C under normal pressure. After being treated at a high temperature of 250°C for 1000 hours, its mechanical properties have little change. PTFE has a very low friction coefficient and is a good anti-friction and self-lubricating material. Its static friction coefficient is smaller than the dynamic friction coefficient, so it has the advantages of small starting resistance and smooth operation when used to make bearings. Because PTFE is non-polar, heat-resistant and non-absorbent, it is also an excellent electrical insulating material. It also has excellent aging resistance, non-stickiness and non-combustibility. The bars, pipes, films, bearings, gaskets, valves and other special-shaped materials and parts are widely used in machinery, chemical industry, aviation, electrical and electronics, national defense industry, cutting-edge technology, medical and health care and electrical insulation and other fields.
