The unique function of PTFE tube makes it widely used in chemical, petroleum, textile, food, paper, medicine, electronics and machinery industries and marine fields.

1. Application of anti-erosion function

Because rubber, glass, metal alloys and other materials in the erosion resistance of defects, it is difficult to meet the premise of harsh temperature, pressure and chemical media coexistence of the environment, the resulting loss of the proportion of amazing. The ptfe material with its excellent erosion resistance function, has become the main erosion resistance materials in petroleum, chemical, textile and other industries. Its detailed applications include: conveying corrosive gas pipe, exhaust pipe, steam pipe, rolling mill high-pressure oil pipe, aircraft hydraulic system and cold pressure system of the Senior high school low-pressure pipeline, distillation tower, heat exchanger, kettle, tower, tank lining, valves and other chemical equipment.

The function of the seal has a great influence on the efficiency and function of the whole machine equipment. ptfe material has the characteristics of corrosion resistance, aging resistance, low friction coefficient and non-stick, wide temperature range and good elasticity, which makes it very suitable for manufacturing seals with high corrosion resistance and operating temperature higher than 100 ℃. Such as machine, heat exchanger, high pressure vessel, large diameter vessel, valve, pump groove flange seal, glass reaction pot, flat flange, large diameter flange seal, shaft, piston rod, valve rod, worm pump, pull rod seal and so on.

2. Application of low friction function in load

Because the friction department of some equipment is not suitable for lubrication, for example, when lubricating grease is dissolved by solvent and fails, or products in the fields of papermaking, pharmacy, food, textile and other industries need to avoid lubricating oil contamination, this makes filling ptfe material the most ideal material for oil-free lubrication (direct load bearing) of mechanical equipment parts. This is due to the fact that the friction coefficient of this material is the lowest among the known solid materials. Its detailed uses include bearings for chemical equipment, papermaking machinery, agricultural machinery, used as piston rings, machine tool guide rails, guide rings; widely used in civil construction projects as bridges, tunnels, steel roof trusses, large chemical pipelines, storage tanks The supporting slider, as well as used as bridge bearings and bridge swivel, etc.

3, in the electronic and electrical applications

The inherent low loss and small dielectric constant of ptfe material enable it to be made into enameled wires for micro motors, thermocouples, control devices, etc. ptfe film is an ideal insulating material for manufacturing capacitors, radio insulating gaskets, insulating cables, motors and transformers, and is also one of the indispensable materials for electronic components in aerospace and other industries. The selective permeability of fluoroplastic film, which has high permeability to oxygen but small permeability to water vapor, oxygen sensors can be manufactured; the use of fluoroplastics at high temperature, high pressure to the characteristics of the polar charge deviation phenomenon, can be manufactured microphones, speakers, robot parts, etc.; the use of its low refractive index characteristics, can be manufactured optical fibers.

4. Application in Medical and Pharmaceutical

The expanded ptfe material is purely inert, has very strong biological adaptability, 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, so it can be used in a variety of rehabilitation solutions, including artificial blood vessels and patches for soft tissue regeneration and surgical sutures for blood vessels, heart, general surgery and plastic surgery.

5. Application of anti-sticking function

ptfe material has the smallest surface tension in solid materials, does not adhere to any substances, and also has excellent characteristics of high and low temperature resistance, so that it is widely used in anti-sticking aspects such as manufacturing non-stick pans. The anti-sticking process mainly includes two kinds: installing ptfe parts or sheets on the substrate, and setting ptfe coating or lacquered cloth composite with glass on the substrate through heat shrinkage.

With the continuous development of material application technology, the three major shortcomings of ptfe materials: cold flow, difficult to weld, difficult to melt processability are gradually being overcome, so that it is in optics, electronics, medicine, petrochemical oil anti-seepage and other fields of application prospects more broad.
