What is PTFE ?

1. PTFE is a fluorocarbon based polymer.

2. PTFE's mechanical properties are low compared to other plastics, and can be used over a wide temperature range.

3. Mechanical properties are often enhanced by adding fillers.

4. It has excellent thermal and electrical insulation properties and a low coefficient of friction.

5. PTFE is very dense and cannot be processed by melting.

6. PTFE must be compressed and sintered to form useful shapes.

Application of PTFE (Polytetrafluoroethylene)

The unique performance of ptfe makes it widely used in industrial and marine operations such as chemical industry, petroleum, textile, food, papermaking, medicine, electronics and machinery.

　　 1. Application of anti-corrosion performance

Because rubber, glass, metal alloys and other materials have defects in corrosion resistance, it is difficult to meet the harsh conditions of temperature, pressure, and an environment where chemical media coexist, and the resulting losses are quite amazing. With its excellent corrosion resistance, ptfe material has become the main corrosion-resistant material in the petroleum, chemical, textile and other industries. Its specific applications include: conveying pipes, exhaust pipes, steam pipes for transporting corrosive gases, high-pressure oil pipes for steel rolling mills, high, medium and low pressure pipes for aircraft hydraulic systems and cold-pressing systems, distillation towers, heat exchangers, kettles, towers, and tanks Lining, valves and other chemical equipment

The performance of the seal has a great influence on the efficiency and performance of the entire machine and equipment. The ptfe material has the characteristics of corrosion resistance, aging resistance, low friction coefficient and non-stickiness, wide temperature resistance range, and good elasticity, making it very suitable for the manufacture of seals with high corrosion resistance requirements and service temperatures higher than 100°C. Such as machinery, heat exchangers, high pressure vessels, large diameter vessels, valves, pumps groove flange seals, glass reactors, flat flanges, large diameter flange seals, shafts, piston rods, valve rods, Worm gear pumps, tie rod seals, etc.

　　2. Application of low friction performance in load

Because the friction part of some equipment is not suitable for lubrication, such as the occasions where the lubricating grease will be dissolved by the solvent and become invalid, or the products in the industrial fields such as papermaking, pharmaceuticals, food, textiles, etc. The most ideal material for mechanical equipment parts without oil lubrication (to bear the load directly). This is because the friction coefficient of this material is the lowest among known solid materials. Its specific uses include bearings for chemical equipment, papermaking machinery, agricultural machinery, as piston rings, machine tool guides, guide rings; widely used in civil engineering projects as bridges, tunnels, steel structure roof trusses, large chemical pipelines, storage tanks Support sliding block, and used as bridge support and bridge swivel, etc.

　　3. Applications in electrical and electronic

The inherent low loss and small dielectric constant of ptfe material make it can be made into enameled wire for use in micro motors, thermocouples, control devices, etc.; ptfe film is ideal for manufacturing capacitors, radio insulation gaskets, insulated cables, motors and transformers Insulating material is also one of the indispensable materials for aerospace and other industrial electronic components; using the selective permeability of fluoroplastic film that has high oxygen permeability and low water vapor permeability, oxygen sensors can be manufactured; Utilizing the characteristics of fluorine plastics in the phenomenon of polar charge deviation under high temperature and high pressure, microphones, speakers, robot parts, etc. can be manufactured; using its low refractive index characteristics, optical fibers can be manufactured.

　　4. Application in medical and medicine

Expanded ptfe material is pure inert, has very strong biological adaptability, will not cause rejection of the body, has no physiological side effects to the human body, can be disinfected by any method, and has a microporous structure, which can be used for 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-stick performance

Ptfe material has the smallest surface tension among solid materials, does not adhere to any substance, 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 putting ptfe coated or glass composite varnished cloth on the substrate through heat shrinkage.

With the continuous development of material application technology, the three shortcomings of ptfe materials: cold flow, difficult to weld, and difficult to melt processability are gradually being overcome, so that it can be used in optics, electronics, medicine, petrochemical oil transport and anti-seepage, etc. Broader application prospects in multiple fields
