PTFE spring tube, FEP spring tube and PFA spring tube can all be called "Teflon spring tube". Because PTFE, FEP and PFA have different properties, the corresponding products like plumbers teflon tapes have different properties.
Name: PTFE coiled tube, PTFE spiral tube, PTFE spring tube, pressure-resistant PTFE spring tube, Teflon telescopic tube, PTFE spiral tube.
Uses: PTFE tubes and high quality teflon tape are widely used in the fields of machinery, chemical industry, aviation, electrical electronics, national defense industry, cutting-edge science and technology, medical care and electrical insulation, etc.
Product features: PTFE tube and gas tape ptfe has excellent chemical stability, can withstand all strong acids, alkalis and strong oxidants, and does not react with various organic solvents. PTFE can be used for a long time at -180℃~250℃ under normal pressure. After being treated at 250℃ for 1000h, its mechanical properties have little change. Heat resistant brown heat resistant teflon tape is a good antifriction and self-lubricating material with low friction coefficient, and its static friction coefficient is less than that of dynamic friction coefficient, so it has the advantages of low starting resistance and smooth running. PTFE heat seal tape is an excellent electrical insulation material because of its non-polarity, heat resistance and non-absorption. It also has excellent aging resistance, non-viscosity and incombustibility. Teflon pipe is extruded from PTFE dispersion resin paste. Used for wire insulation sheath, corrosive fluid medium pipeline, various electrical insulation parts used at high frequency, etc.
Name: FEP spiral tube, FEP spiral tube, F46 spring tube
Performance:
High and low temperature resistance:-196-200℃; Non-viscosity and no fouling, no flow inside and outside the pipe wall; Electrical reliability and high insulation. The dielectric constant viscosity is 2.1 at 601HZ-60MH. Even if the surface of high pressure thread tape is damaged by diving, it will not generate electricity; Track volume resistance > 10180M surface resistance > 2 * 10130m; Arc resistance > 165 seconds without leakage;
Corrosion resistance: it only reacts with elemental fluorine and alkali metals at high temperature, but has no effect on all other concentrated and dilute inorganic organic acids, bases and esters;
Low water absorption: low water absorption rate < 0.01%;
Incombustibility: it will not burn in the air (oxygen index > 95V0L%), which is non-toxic and physiologically inert;
High transparency: The refractive index of light is the lowest among all plastics;
Weather resistance: it can be exposed to ozone and sunlight for a long time; Easy secondary processing.
Name: PFA spiral tube, PFA spiral tube, PFA spring tube, soluble poly (perfluoroethylene propylene) spring tube, transparent Teflon tube.
Characteristics:
Service temperature: -200℃ to 260℃;
Aging resistance: it can be exposed to ozone and sunlight for a long time without aging;
High transparency: the refractive index of all plastics is low, and the flow of medium in the pipe can be seen very intuitively;
Corrosion resistance: high temperature resistant teflon tape can bear the action of all strong acids, strong oxidants, strong reductants and various organic solvents except molten alkali metal, fluorinated medium and temperature higher than 300.
Application:
1. Liquid crystal manufacturing device; 2. Tube for single-core optical fiber with whole body and single-end luminescence; 3. Heat exchanger, steam piping; 4. High-purity reagent delivery pipe; 5, all kinds of corrosive medium (harsh solvent) transmission pipeline; 6, all kinds of frequency wire and cable sheath, slot insulation tube; 7. Slot insulation pipe for submersible motor; 8. Tube for air conditioning harness assembly; 9. Pipe for all-inclusive fluorine plastic type 0 sealing ring.
PTFE, FEP and PFA spring tubes can be made into double-row and multi-row spring tubes, which can be customized by many heat tape pipe manufacturers according to customer requirements; Multiple color combinations; Same pipe diameter and different pipe diameters can be combined and processed.
