Fluoroplastics, a general term for fluoropolymers, are commonly known as "the king of plastics". Because of their excellent electrical properties, thermal stability, and mechanical and physical properties, they are widely used as wire and cable insulation materials.
Fluoroplastic high-temperature wires have the characteristics of high temperature resistance and flame retardancy. They are mainly used in aviation wires, wiring of electronic and electrical equipment, and lighting wires for special occasions. The specific characteristics are as follows:
1.High temperature resistance
Fluoroplastic high-temperature wires have extraordinary thermal stability and are suitable for high temperature environments of 150 ~ 200 degrees, while common polyethylene and polyvinyl chloride cables are only suitable for 70 ~ 90 degree working environments. In addition, under the condition of the same cross-section conductor, the fluoroplastic high-temperature wire can transmit a larger allowable current, which greatly increases the range of use of the cable.
2.Good flame retardancy
Fluoroplastics have a high oxygen index, a small flame diffusion range during combustion, and a small amount of smoke. Once a fire occurs, people can be evacuated for a certain period of time without being overwhelmed by thick smoke, and strive for valuable rescue time.
3.Excellent electrical performance
Compared to polyethylene, fluoroplastics have a lower dielectric constant.
4.Perfect mechanochemical performance
Fluoroplastics have high chemical bond energy, high stability, hardly affected by temperature changes, excellent weather resistance and mechanical strength, and are not affected by various acids, alkalis and organic solvents, so they are suitable for the environment Great climate change and corrosive occasions.
5, conducive to welding connections
In electronic instruments, many wirings are connected by welding. Due to the low melting temperature of general plastics, they are easy to melt at high temperatures. Skilled welding techniques are required, and some solder joints must have a certain welding time. Fluoroplastic high-temperature wires are popular reasons, such as the internal wiring of communication equipment and electronic instruments.
Fluoroplastic high-temperature wire has such superior performance, so it has gradually replaced PVC wire, and has become the first choice for the electrical and electronic industry.
