Aircraft Cable Manufacturers: Teflon cable vs silicone cable PVC cable performance comparison

Teflon material, with its unique physicochemical properties, occupies a pivotal position in the manufacture of aviation cables.

TST CABLES, an aircraft cable manufacturer, summarizes five advantages of Teflon in aviation cables

First, excellent high temperature resistance

Teflon material is able to work stably for a long period of time in environments as high as 260℃. This characteristic is crucial for high temperature areas such as aviation engines, ensuring that cables will not fail due to thermal aging in high temperature environments.
Compared with other materials, such as silicone cables are usually resistant to temperatures up to about 200 ℃, Teflon’s high temperature resistance is more outstanding, better able to meet the requirements of the aviation field of high temperature environment.

Second, excellent corrosion resistance

Teflon is inert to most chemicals and solvents, resistant to strong acids and alkalis. This corrosion resistance allows Teflon cable to remain stable in complex chemical environments, reducing cable failures caused by chemical corrosion.
This is an extremely important characteristic for aviation environments that are often exposed to a variety of chemicals.

Third, stable electrical performance

As a class C insulating material, Teflon has excellent electrical properties, can withstand high voltages and maintain a stable insulation resistance. This characteristic is essential to ensure the stability and safety of aviation electrical systems.
The stable electrical performance of Teflon cables can effectively prevent the occurrence of electrical faults and improve flight safety.

Fourth, lightweight and durable

Teflon cable is relatively lightweight, which helps to reduce the burden of flight and improve flight efficiency. In the field of aviation, every gram of weight reduction means lower energy consumption and improved performance.
At the same time, Teflon cables also have excellent abrasion resistance and durability, suitable for frequent bending and movement of the environment, extending the service life of the cable.

V. High Flame Retardant

Teflon materials have excellent flame retardant properties, which is particularly important in the aviation field. In emergency situations, the flame retardant properties of Teflon cables help to reduce the risk of fire and buy valuable escape time for passengers and crew.
In summary, the importance of Teflon material in aviation cables cannot be overstated. Its excellent high temperature resistance, excellent corrosion resistance, stable electrical properties, lightweight and durable characteristics, and high flame retardancy make Teflon cables one of the preferred materials in the aviation field.
