Material of silicone high temperature wire

The material properties of the silicone high temperature wire are not reflected by the thickness, but according to the standard requirements.

If a certain index fails to meet the standard, it will directly affect the quality of the silicone high-temperature wire. After the silicone high temperature wire is laid, it will be energized for a long time to generate heat energy. The allowable working temperature of the conductor is 70°C, and the allowable long-term working temperature of the silicone high-temperature wire is 180°C. In summer, the operating temperature will rise.

These temperatures will be dissipated through the outer jacket. The thickness of the sheath will increase, and the heat energy will be difficult to dissipate, which will affect the service life of the silicone high-temperature wire. Under the action of heat, the insulating layer will undergo a series of physical and chemical changes, losing its original excellent performance, resulting in a significant decrease in insulation performance, or even a short circuit, affecting the normal operation of the unit. 

PVC wire generally has a temperature resistance range of -15 to 80, while silicone high temperature wire can reach -60 to 200. PVC wires have a short service life, generally about two years, poor flexibility, poor aging resistance, and are easy to crack in the sun, suitable for indoor lamps and household appliances.

PVC wire is relatively hard, smooth surface and high brightness. The cost of PVC wire of the same specification is much lower than that of silicone high temperature wire, the compressive strength is lower than that of silicone wire, and the bending recovery ability of PVC wire is poor.

Once bent and folded, it is difficult to return to its original shape. However, silicone high-temperature wires also have disadvantages, such as poor tear resistance of the sheath and high manufacturing costs. 

The above explanations are the main features and identification skills of the silicone high-temperature wire. I hope it will be helpful to you after reading it.
