Teflon capillary manufacturer
Teflon capillary tube is a special tube made of polytetrafluoroethylene (ptee, commonly known as Teflon, plastic king) material after extrusion and sintering, drying, high temperature sintering, and shaping. Because the tube is about the same size as a blood vessel, it is also called Teflon capillary.
At present, Teflon capillary tubes are widely used in important technology industries such as machinery, electronic appliances, automobiles, aerospace, chemicals, computers, electric heating, military, and communications, such as miniature transformers.
Teflon capillary has a high degree of chemical stability: it can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, etc., strong alkalis, strong oxidants, reducing agents and various organic The role of solvents. It is very suitable for feeding high-purity chemicals.
Teflon capillary features:
Has a low coefficient of friction: The coefficient of friction is generally only 0.04, which is a very excellent self-lubricating material, and the coefficient of friction does not change with changes in temperature.
Excellent adhesion resistance, the inner wall of the tube is not easy to adhere to colloids and chemicals. ※Excellent aging resistance, can be used outdoors for a long time.
Excellent electrical insulation properties of Teflon capillaries: ptfe is a highly non-polar material with good dielectric properties, extremely high resistance, and a dielectric constant of about 2.0, which is small among all electrical insulation materials.
Part of the Teflon capillary tube has high transparency, and the internal fluid condition can be easily observed.
