Introduction of 1. Fep Spring Tube
Spring telescopic tube name: Teflon spiral tube, Fep spiral tube, Fep spiral tube, Fep spring tube.
Teflon telescopic tube, also known as Teflon spring tube, did not know that spring tube has such an individual name. When it comes to spring tubes, you may be more conceptual. Teflon spring tube, as the name suggests, looks like a spring, but the material is different, there are PTFE, FEP, PFA and other materials of the spring tube. Teflon spring tube is a spring tube made of Teflon material, which is often used in heat exchangers and steam tubes. Various frequency wire and cable sheaths, slot insulation tubes; Various corrosive media (harsh solvents) delivery pipelines; Liquid crystal manufacturing device; High purity reagent delivery pipe; Insulation tube for oil motor; Tubes for single-ended luminous single-core optical fibers, tubes for air conditioning wiring harness components, etc.
Common color: transparent, black.
2. Fep spring tube performance
1. High and low temperature resistance:-196-260 ℃ high temperature, strength twice as large as F4.
2, non-sticky, spell water spell oil, pipe wall inside and outside no fouling, no flow.
3, electrical reliability, high insulation 601HZ-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: the air will not burn (oxygen index> 95V0L %) non-toxic with physiological inertia;
7, high transparency: the lowest refractive index in all plastics; weather resistance: can be exposed to ozone, sunlight for a long time;
8. Easy secondary workability: self-sealing, self-welding, flanging and tube making.

3. Fep spring tube commonly used specifications:
Inner diameter * outer diameter (unit: mm)
Metric: 2*4 3*5 4*6 5*7 6*8 8*10 8*12 9*12 10*12 12 12*14 14*16*18 18*20
Imperial: 1/8 inch (1.6*3.2) 1/4(3.96*6.35) 3/8(6.35*9.525)1/2 inch (9.5*12.7) 3/4(15.88*19.05) 1(22.2*25.4)
Can produce specifications, inner diameter of 0.5mm to 200mm, wall thickness of 0.12mm to 3mm.
Specific specifications can be asked Fep manufacturer Teflon tube little sister's home, etc.
Application features of 4. fep spring tube:
1, high temperature wire, cable insulation, anti-corrosion equipment, sealing materials, pump valve bushing, and chemical containers;
2, suitable for the production of corrosion-resistant parts, wear parts, seals, insulation parts and medical equipment parts;
3, poor liquidity, easy to decompose, decomposition of corrosive gas. It is advisable to strictly control the molding temperature not to exceed 475 degrees, the mold should be heated to 150-200 degrees, and the resistance of the gating system to the material flow should be small;
4. Translucent pellets, injection molding, extrusion molding. The molding temperature is 350-400 degrees, and more than 475 degrees is easy to cause discoloration or bubbles. And note that demoulding will be more difficult.
5. polyethylene glycol propylene (FEP) spring tube use:
1. Liquid crystal manufacturing device;
2. Full-body single-end light-emitting single-core optical fiber tube;
3. Heat exchanger, steam piping;
4. High purity reagent delivery tube;
5. All kinds of corrosive medium (harsh solvent) transportation pipeline;
6, various frequency wire and cable sheath, slot insulation tube;
7. Slot insulation pipe for submersible motor;
8. Tube for air conditioning harness assembly;
9. All-inclusive fluorine plastic 0-type sealing ring tube.
