Introduction to 1. FEP
The full name of FEP is Fluorinated ethylene propylene, which translates as fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer). FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene. The FEP crystals had a melting point of 304 ° C. and a density of 2.15g/cc. FEP can be applied to soft plastics, the tensile strength, wear resistance, creep resistance is lower than many engineering plastics.
Brief Introduction of 2. FEP Tube
1. Performance, parameters
Volume resistance> 1018 Ωm, surface resistance> 1013 Ω, arc resistance> 165 seconds, no leakage; Low friction dynamic friction coefficient: 0.2-0.3; Non-stickiness, water and oil contact angle θ = 114 о; Non-combustibility, non-combustion in air (oxygen index> 95VOL%), shrinkage ratio 1.7:1.
2. Characteristics
Temperature resistant, polytetrafluoroethylene F46, FEP heat shrinkable tube: -200-200 ℃
Meltable polytetrafluoroethylene (PFA) heat shrinkable tube: -200-250 ℃
Corrosion resistance only high temperature element fluorine, alkali metal and its role, for all other concentrated, dilute inorganic organic acids, alkali, ester has no effect.
3. Application
Teflon FEP heat shrinkable tube has outstanding wear resistance, chemical corrosion resistance and high temperature performance, especially suitable for high temperature performance of the occasion, used to connect the weld insulation protection and pressure relief and distinction identification of covered components.

3. FEP tube characteristics
1, high and low temperature resistance: working temperature -200 ℃ ~ 200 ℃, the strength is two times larger than F4.
2, non-sticky, spell water spell oil, inside and outside the pipe wall without fouling, without flow, very low coefficient of friction;
3, electrical reliability, low dielectric constant (insulation), high insulation 601 HZ-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 and no leakage.
4, corrosion resistance: only high temperature element fluorine, alkali metal and its role, for all other concentrated, dilute inorganic organic acids, alkalis, esters have no effect;
5, low water absorption, low absorption rate <0. 01%;
6, non-combustible, non-combustible in the air (oxygen index> 95V0L %) non-toxic with physiological inertness;
7. High transparency, the lowest light refractive index in all plastics; transparent hose; weather resistance: can be exposed to ozone, sunlight for a long time, anti-ultraviolet (will not age);
8. Easy secondary workability: self-sealing, self-welding, flanging and tube making.
4. FEP tube FAQ summary
1. fep pipe manufacturer:
Teflon tube little sister home, etc.
2, what is the fep tube tube:
Polyfluoro ethylene propylene (F46, FEP) heat shrinkable tube.
3. fep tube extrusion molding:
FEP, like other meltable fluoroplastics, is hot-molded, die-cast, and extruded (vacuum and air pressure molding) using common methods. In standard equipment, all molded parts in contact with molten fluoroplastics shall be made of corrosion-resistant alloys. FEP processing molding process manufacturer Shenzhen Dankai.
4. what industries are feps used:
The application range of FEP is the same as PTFE, and it is used in electrical, radio, electronics, chemical industry, machinery manufacturing, refrigeration, medicine and other industrial sectors.
5. fep tube use:
FEP is used for film printed boards, wire and cable insulation, generator wire windings, electrical insulation products (sheets, rods, tubes, racks and insulators), corrosion-resistant structural products (oil-free mechanical parts), coatings and glass paint. Excellent corrosion resistance makes it used in chemical equipment, heat exchangers, fractionation towers, pumps, valves, pipes, seals, pipe lining, laboratory transparent utensils, etc. FEP extruded thin-walled tubes are used in heat exchangers for heating and cooling strongly corrosive liquids in the range of -200 to 200°C.
