The inherent low loss and small dielectric constant of PTFE plastic raw materials can be used to make magnet wire for micro-motors, thermocouples, control devices, etc.; PTFE plastic film is made of capacitors, radio insulation pads, insulated cables, motors and The ideal insulating material for transformers is also one of the indispensable materials for industrial and avionics and other industrial electronic components; the use of fluorine plastic films for high oxygen permeability and low permeability for water vapor can be manufactured through this selective permeability. Oxygen sensor; The use of fluorine plastic in the high temperature, high voltage under the phenomenon of polar charge deviation phenomenon, can create microphones, speakers, robot parts, etc.; use of its low refractive index characteristics, can manufacture optical fiber.
Corrosion resistance application
PTFE materials have become the main corrosion-resistant materials in the petroleum, chemical and textile industries due to their excellent corrosion resistance. Its specific applications include: conveying pipes for corrosive gases, exhaust pipes, steam pipes, high pressure oil pipes for rolling mills, high and low pressure pipelines for aircraft hydraulic systems and cold pressure systems, distillation towers, heat exchangers, kettles, towers, tanks Lining, valves and other chemical equipment. The
The performance of the seal has a great influence on the efficiency and performance of the entire machine equipment. PTFE plastic materials have the characteristics of corrosion resistance, aging resistance, low coefficient of friction and non-stickiness, wide temperature range, and good elasticity, which make them very suitable for the manufacture of seals with high corrosion resistance and using temperatures above 100°C. Seals for grooved flanges of machines, heat exchangers, high pressure vessels, large diameter vessels, valves, pumps, glass reaction pots, flat flanges, seals for large diameter flanges, shafts, piston rods, valve stems, Worm pump, tie rod seals, etc.
Low friction performance applications
Because some parts of the friction part of the equipment should not be lubricated, for example, when the grease is dissolved by solvents and fails, or in the paper, pharmaceutical, food, textile and other industrial fields, it is necessary to avoid contamination of the oil, which makes the PTFE filled plastic materials. It is the ideal material for oil-free lubrication of mechanical equipment parts. 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, piston rings, machine tool guides, guide rings, and widely used as bridges, tunnels, steel trusses, large chemical pipelines, and storage tanks in civil engineering projects. Support sliders, as well as bridge supports and bridge swivels.
