Product features: PTFE extrusion tube(ptfe)It has excellent chemical stability, can withstand all strong acids, strong alkalis, strong oxidants, and variousorganic solventNor happen
role.PTFEThe use of a wide range of temperature, atmospheric pressure can be used for a long time-180 ℃ ~ 250 ℃, at 250 ℃ high temperature treatment for 1000h, its mechanical properties change very
Small.PTFEHas a very low friction factor, is a good antifriction, self-lubricating material, its static friction coefficient is lesscoefficient of dynamic frictionTherefore, it is used to make bearings.
The advantages of small dynamic resistance and smooth operation. DuePTFEIt is non-polar, heat-resistant and non-absorbent, so it is an excellent electrical insulation material. Also has excellent aging resistance
Sex, non-sticky and non-flammable. PTFE extrusion tube is made of PTFE dispersion resin paste extrusion! Wire insulation sheath, corrosive fluid medium pipeline,
Electrical insulation parts used at various high frequencies.
2.FEPBourdon tube.
1,Name:FEPspiral tube,FEPSpiral tube,F46spring 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. iron fluoride
Dragon spring tube, as the name implies, looks like a spring, but the material is different, there arePTFE, FEP, PFA and other materials of the spring tube. Teflon spring tube is made
TeflonThe spring tube made of the material is often used in heat exchangers and steam pipes; various frequency wire and cable sheaths, slot insulation pipes; various
Corrosive medium(harsh solvent) delivery pipeline; Liquid crystal manufacturing equipment; High purity reagent delivery pipe; Insulation pipe for oil motor; Single-ended generator
Light single-core fiber tube, air conditioning harness components with tubes and other fields.

3,FEPBourdon tube performance
（1）High and low temperature resistance:-196-200 ℃high temperature, strength ratioF4Twice as big.
（2）Non-stick,Spell water and oil, no fouling or flow inside and outside the pipe wall.
（3）Electrical reliability, high insulation601HZ-60MHDielectric normal viscosity at high and low temperatureFor2.1. Even if the surface is damaged by diving, it will not produce.
raw conduction; track volume resistance> 10180Msurface resistance>2*10130MArc resistance>165seconds without leakage.
（4）Corrosion resistance: only element fluorine at high temperature,alkali metalIt works with all other concentrated and dilute inorganic organic acids, alkalis and esters.
Use;
（5）low water absorption:low absorption rate<0. 01%;
（6）non-combustibility:Will not burn in the air(oxygen index>95V0L %)Non-toxic with physiological inertia;
（7）High transparency:Lowest optical refractive index of all plastics; weather resistance:Can be exposed to ozone, sunlight for a long time;
（8）Easy secondary processing.
