- Jun 15, 2017 -

Teflon tube is the use of high-quality plunger extrusion pipe, the use of special processing technology, so that steel pipe and plastic pipe close together, can withstand positive pressure 18.0Mpa, negative pressure: 77Kpa; in -60 ℃ ~ +260 ℃ within the normal use, with reliable and excellent corrosion resistance. PTFE Tube Transport high temperature corrosive gas, liquid, which is other pipes can not be replaced.

Chinese name polytetrafluoroethylene tube

English name PTFE

Water-soluble non-absorbent

Appearance tubular

Application of high temperature corrosive gas, liquid

Safety Description Chemical stability

Use temperature -180 ℃ ~ + 260 ℃

Wire insulation sheath, corrosive fluid medium pipe, a variety of high frequency use of electrical insulation parts.

Teflon tube has excellent chemical stability, resistance to all strong acid, alkali, strong oxidants, and a variety of organic solvents do not play a role. PTFE use temperature range is wide, under normal pressure can be used for a long time -180 ℃ ~ 250 ℃, at 250 ℃ high temperature treatment 1000h, its mechanical properties change is very small. PTFE has a very low friction factor, is a good anti-friction, PTFE Tube self-lubricating material, the static friction coefficient is less than the dynamic friction coefficient, so the bearings used to produce a small starting resistance, smooth operation. Because PTFE is non-polar, heat-resistant and non-absorbent, PTFE Tube it is an excellent electrical insulation. Also has excellent anti-aging, non-sticky and non-flammable.

It is widely used in machinery, chemical industry, aviation, electrical and electronic, national defense industry, cutting-edge technology, medical and health and electrical insulation. It is widely used in machinery, And other fields.

The unique performance of Teflon has a wide range of applications in the fields of chemical, petroleum, textile, food, paper, medical, PTFE Tube electronics and machinery industries and marine operations.

1, the application of anti-corrosion properties

As the rubber, glass, metal alloys and other materials in the corrosion-resistant defects, it is difficult to meet the harsh conditions of temperature, pressure and chemical medium coexistence of the environment, the resulting loss is quite amazing. The ptfe material with its excellent corrosion resistance, has become the oil, chemicals, textiles and other industries the main corrosion-resistant materials. The specific applications include: conveying corrosive gas transmission pipe, exhaust pipe, steam pipe, rolling mill high pressure tubing, PTFE Tube aircraft hydraulic system and cold pressure system of high and low pressure pipes, distillation tower, heat exchanger, kettle, tower, tank Of the lining, valves and other chemical equipment.

Seal of the performance of the entire machine equipment efficiency and performance have a great impact. Ptfe material with corrosion resistance, aging resistance, low coefficient of friction and non-sticky, wide temperature range, good elasticity characteristics make it very suitable for use in the manufacture of high corrosion resistance requirements, the use of temperature higher than 100 ℃ seal. Such as machine, heat exchanger, high pressure vessel, large diameter container, valve, pump groove flange seal, glass reaction pot, flat flange, large diameter flange seal, shaft, piston rod, Worm gear, rod seals and so on.

2, low friction performance in the application of the load

As the friction parts of some equipment should not be lubricated, for example, in the case where lubricating grease is dissolved by solvent or in the fields of papermaking, pharmaceutical, food, textile and other industries, it is necessary to avoid contamination of the lubricating oil, which makes the filling ptfe material Mechanical equipment parts without oil lubrication (direct load) of the most ideal material. PTFE Tube This is because the friction coefficient of the material is the lowest of known solid materials. Its specific uses include for the chemical equipment, paper machinery, agricultural machinery bearings, used as a piston ring, machine tool guide, guide ring; in civil engineering works widely used as bridges, tunnels, steel roof trusses, large chemical pipes, Support sliders, as well as bridge bearings and bridge dike and so on.

3, in the electrical and electronic applications

Ptfe material inherent low loss and small dielectric constant make it can be made into enameled wire for micro-motor, thermocouple, control device, etc .; ptfe film is ideal for manufacturing capacitors, radio insulation pads, insulated cables, motors and transformers Insulation materials, but also aerospace and other industrial electronic components indispensable one of the materials; the use of fluorine plastic film on the oxygen permeability, and the permeability of water vapor permeability of this choice of permeability, can produce oxygen sensors; The use of fluorine plastic in high temperature, high pressure under the phenomenon of extreme charge deviation phenomenon, can produce microphones, speakers, robots on the parts; the use of its low refractive index characteristics, can manufacture optical fiber.

4, in the medical and medical applications

The ptfe material is purely inert and has very strong biocompatibility, does not cause rejection of the body, has no physiological side effects on the human body, can be sterilized by any method, and has a microporous structure, which can be used for a variety of rehabilitation solutions , PTFE Tube Including artificial blood vessels and patches for soft tissue regeneration, and surgical staples for blood vessels, heart, general surgery, and orthopedic surgery.

5, the application of anti-sticking performance

The ptfe material has the smallest surface tension in the solid material, does not adhere to any material, but also has excellent resistance to high and low temperature characteristics, so that it is used in the manufacture of non-stick pan anti-sticky application is very extensive. The anti-sticking process mainly comprises two types: the ptfe part or the sheet is mounted on the substrate, and the ptfe coating or the paint composite with the glass is heat-shrunk to cover the substrate.

With the continuous development of material application technology, ptfe material of the three major shortcomings: cold flow, difficult to weld, PTFE Tube difficult melt processing is gradually being overcome, so that it in the optical, electronics, medicine, petrochemical oil seepage and so on A wide range of areas of application prospects more broad.
