Teflon casing is PTFE (commonly known as Teflon casing) material as raw material, by extrusion, sintering, drying, high temperature sintering, shaped special pipe. Teflon casing, also known as Teflon, PTFE. Widely used in machinery, electronic appliances, automotive, aerospace, chemical, computer, electric heating, military, communications and other important technology industries, such as micro-transformers.
Teflon casing is made of polytetrafluoroethylene dispersion resin and organic solvent as extrusion aids, dried and sintered. According to the size of the tube can be divided into capillary andTwo types of HOSE tubes. The inner diameter of the hose is greater than 4mm, and the inner diameter of the capillary is less than or equal to 4mm.
Teflon casing has excellent dielectric properties and chemical resistance, high temperature resistance, high pressure resistance, non-absorbent, non-sticky, non-conductive, low friction coefficient and non-aging characteristics. Widely used in transformers, electronic appliances, communication equipment, chemical fluids, machinery manufacturing, medical equipment, automobiles, aerospace and other fields. below we take a look at the characteristics of teflon casing.
1. High chemical stability: Teflon casing is resistant to all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, strong alkali, strong oxidizing agent, reducing agent and various organic solvents, which is very suitable for adding high purity chemicals.
2. Low friction coefficient: The friction coefficient of Teflon casing is generally only 0.04, which is a good self-lubricating material, and the friction coefficient does not change with temperature.
3. Excellent anti-sticking performance, and the inner wall of the tube is not easy to adhere to colloids and chemicals.
4. It has excellent anti-aging performance and can be used outdoors for a long time.
5. Excellent electrical insulation properties: PTFE is a highly non-polar material with good dielectric properties and high resistance. The dielectric constant is about 2.0, the smaller of all electrical insulating materials.
6. Some Teflon casing has high transparency, and the internal fluid is easy to observe.
