The unique properties of PTFE composite fabric/cloth make it widely used in industrial and marine operations such as chemical industry, petroleum, textile, food, papermaking, medicine, electronics and machinery.

1. Application of PTFE composite fabric/cloth in electronic and electrical aspects
The inherent low loss and small dielectric constant of PTFE composite fabric/cloth materials enable it to be made into enameled wires for use in micro motors, thermocouples, control devices, etc.; PTFE composite fabric/fabric films are used to manufacture capacitors, radio insulating liners, An ideal insulating material for insulated cables, motors and transformers, it is also one of the indispensable materials for industrial electronic components such as aerospace and aerospace. The use of fluoroplastic films has a high permeability to oxygen but low permeability to water vapor. Oxygen sensors can be made by using the properties of fluoroplastics; microphones, speakers, parts on robots, etc. can be made by using the characteristics of polar charge deviation under high temperature and high pressure; using the characteristics of low refractive index, optical fibers can be made.

2. Application of low friction properties of PTFE composite fabric/cloth in terms of load
Because the friction parts of some equipment are not suitable for lubrication, for example, in situations where lubricating grease will be dissolved by solvents and become ineffective, or products in industrial fields such as papermaking, pharmaceuticals, food, and textiles need to avoid lubricating oil contamination, this makes filled PTFE composite fabrics / Cloth material has become an ideal material for oil-free lubrication of mechanical equipment parts (directly bearing load). 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, and agricultural machinery, as piston rings, machine tool guide rails, and guide rings; in civil construction projects, it is widely used as bearings for bridges, tunnels, steel structure roof trusses, large chemical pipelines, and storage tanks. Support slide blocks, and be used as bridge supports and bridge swivels, etc.

3. Application of anti-adhesive properties of PTFE composite fabric/cloth
PTFE composite fabric/cloth material has a small surface tension among solid materials and does not adhere to any substance. It also has excellent high and low temperature resistance, making it widely used in anti-stick aspects such as making non-stick pans. The anti-adhesive process mainly includes two types: installing PTFE composite fabric/fabric components or sheets on the substrate, and placing PTFE composite fabric/fabric coating or varnished cloth composited with glass through heat shrinkage and covering it on the substrate.
With the continuous development of material application technology, the three major shortcomings of PTFE composite fabric/cloth materials: cold flow, difficulty in welding, and difficulty in melt processing are gradually being overcome, making it widely used in optics, electronics, medicine, and petrochemical industry. The application prospects in various fields such as oil anti-seepage are broader.

4. Application of PTFE composite fabric/cloth in medical and pharmaceutical applications
The expanded PTFE composite fabric/cloth material is purely inert, has very strong biological adaptability, will not cause rejection by the body, has no physiological side effects on the human body, can be sterilized by any method, and has a multi-microporous structure, so it can be used in many applications. Rehabilitation solutions including artificial blood vessels and patches for soft tissue regeneration and surgical sutures for vascular, cardiac, general surgery and orthopedic surgery.

5. Application of anti-corrosion properties of PTFE composite fabric/cloth
Due to the defects in corrosion resistance of rubber, glass, metal alloys and other materials, it is difficult to meet the harsh environment where temperature, pressure and chemical media coexist, and the resulting losses are quite staggering. PTFE composite fabric/cloth material has become the main corrosion-resistant material in petroleum, chemical, textile and other industries due to its excellent corrosion resistance. Its specific applications include: delivery pipes, exhaust pipes, steam pipes for transporting corrosive gases, high-pressure oil pipes for rolling mills, high, medium and low-pressure pipes for aircraft hydraulic systems and cold press systems, distillation towers, heat exchangers, kettles, towers and tanks. Linings, valves and other chemical equipment.
The performance of seals has a great impact on the efficiency and performance of the entire machine and equipment. PTFE material has the characteristics of corrosion resistance, aging resistance, low friction coefficient and non-stickiness, wide temperature range, and good elasticity, making it very suitable for manufacturing seals with high corrosion resistance requirements and operating temperatures above 100°C. Such as seals for grooved flanges of machines, heat exchangers, high-pressure vessels, large-diameter vessels, valves, and pumps, seals for glass reaction pots, flat flanges, large-diameter flanges, shafts, piston rods, valve rods, Worm gear pumps, tie rod seals, etc.
