I. Core Characteristics of Silicone Rubber Cables

1. Extreme Temperature Resistance

High - temperature Resistance: The long - term operating temperature can reach - 60°C to + 180°C. Some special models (such as those with mica tape added) can withstand high temperatures of 200°C - 300°C, and can even endure an instantaneous high temperature of 350°C in the short term (such as in fire scenarios).

Low - temperature Resistance: It still maintains flexibility and is not easy to crack at - 60°C, making it suitable for extremely cold regions or refrigeration equipment.

2. Excellent Electrical Insulation

Silicone rubber has a high dielectric strength (≥20kV/mm) and a large insulation resistance (≥10^14Ω·cm). It can still maintain stable insulation performance in high - temperature and humid environments, and is suitable for high - frequency and high - voltage circuits.

3. Outstanding Physical and Mechanical Properties

Flexibility and Bend Resistance: The molecular chain of silicone rubber is soft, and the cable can be bent and folded frequently, which is suitable for mobile devices (such as robots, drag - chain systems).

Anti - aging and Weather Resistance: It is resistant to ultraviolet rays, ozone, and atmospheric aging. It is not easy to crack after long - term outdoor use, and its service life can reach 10 - 15 years (ordinary PVC cables only have a service life of 5 - 8 years).

4. Chemical Resistance and Environmental Adaptability

It is resistant to oil, acid, alkali, and various chemical solvents (such as alcohol, ketones), but is not resistant to strong oxidants (such as concentrated nitric acid).

Flame Retardancy: Ordinary silicone rubber cables have self - extinguishing properties (meeting UL94 V0 level). Flame - retardant products can add flame retardants to further improve fire - proof performance.

Radiation Resistance: In the environment of γ - rays or electron radiation, its performance decays slowly, making it suitable for scenarios such as nuclear power plants and medical equipment.

5. Other Characteristics

Lightweight: The density of silicone rubber is low (1.1 - 1.3g/cm³), making it lighter than traditional rubber cables.

Non - toxic and Environment - friendly: Silicone rubber materials do not contain halogens, and no harmful gases are released during combustion, which meets environmental protection standards (such as RoHS).
