  1. What material is PTFE

  Polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), many people doubt that ptfe emulsion is a kind of polyfluorotetraethylene polymer chemical material, it is widely used in packaging, electronic and electrical, chemical energy, generally called "not Sticky coating" or "easy to clean material". What material is polytetrafluoroethylene? This material is resistant to acids, alkalis, and various organic solvents, and it is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, its friction coefficient is extremely low, and it has become an ideal coating for easy cleaning of the inner layer of water pipes as well as its lubricating effect. It is now called the "Plastic King".

  There are local customs in different regions, and the name of PTFE is different in different regions. All of them are called PTFE.

  F4 tube, PTFE tube, PTFE tube, Teflon tube, Teflon tube, Teflon tube, Teflon tube, Teflon tube, Teflon tube, Teflon tube, PTFE sleeve Tube, plastic king tube

  Common colors of PTFE: milky white tube, translucent, black

  Unusual colors: yellow, brown, green, blue, red

  Uses of PTFE tube:

  ●Chemical resistance, non-adhesive liquid transfer equipment joints are not covered and protected

  ●Sensor protection

  ●Metal balls are non-adhesive

  ●Protective cover for medicines under high temperature

  ●The outer covering of the optical fiber sheath

  Common features of PTFE tube:

  Operating temperature: -200 degrees to 260 degrees

  Ease of processing: can flanging

  Aging resistance: can be exposed to ozone and sunlight for a long time without aging

  High transparency: the refractive index is low among all plastics, and the flow of the medium in the pig can be viewed directly

  Corrosion resistance: able to withstand the action of all strong acids, strong oxidants, strong reducing agents and various organic solvents except for molten alkali metals, fluorinated media and those above 300°

  2. PTFE pipe specifications

  Polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), is the use of high-quality plunger extruded pipe, using special processing technology to make the steel pipe and plastic pipe tightly combined, can withstand positive pressure 1.6Mpa, negative pressure: 77Kpa ; It can be used normally within -60℃~+260℃, with reliable and excellent corrosion resistance. Transporting highly corrosive gases and liquids at high temperatures cannot be replaced by other pipelines.

  Polytetrafluoroethylene (PTFE) has excellent chemical stability, can withstand all strong acids, strong alkalis, and strong oxidants, and does not interact with various organic solvents. PTFE has a wide operating temperature range. It can be used for a long time at -180℃~250℃ under normal pressure. After 1000h of treatment at 250℃, its mechanical properties will change little.

  PTFE has a very low friction factor, is a good anti-friction, self-lubricating material, its static friction coefficient is less than the dynamic friction coefficient, so it has the advantages of low starting resistance and smooth running when used to make bearings. Because PTFE is non-polar, heat-resistant and does not absorb water, it is also an excellent electrical insulating material. It also has excellent aging resistance, non-stickiness and non-combustibility.

  PTFE tube specifications: common inner diameter * outer diameter (unit: mm)

  Metric system: 2*4 3*5 4*6 5*7 5*8 6*8 8*10 8*12 9*12 10*12 12*14 14*16 16*18 18*20

  British system: 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)

  Other special specifications can be customized

  Shenzhen DanKai Technology Co., Ltd. (ShenZhen DanKai Technology Co.,ltd.), whose predecessor is Dongguan Dandi Insulation Material Co., Ltd.
