Understanding Silicone Cable
Silicone rubber was introduced in the 1940s for cable insulation, but it initially faced challenges in gaining acceptance due to its limited thermal properties, strength issues, and manufacturing difficulties. Over time, these challenges were effectively addressed. With the addition of various fillers and additives, silicone rubber has evolved into a widely favored insulation material, renowned for its stability, non-reactivity, and resistance to harsh environments.
One specific application is silicone cable insulation, which is made from a combination of silicone, carbon, hydrogen, and oxygen. This material can withstand high temperatures while providing excellent flexibility, making it ideal for use in sectors such as metallurgy, energy, electronics, and aviation.
Composition of Silicone Cable
Silicone cables generally consist of the following components:
- Conductors: The core of these cables is made from materials such as copper or tinned copper, which provide excellent electrical conductivity.
- Insulation: Surrounding the conductor is a layer of silicone rubber insulation, which safeguards the conductor from environmental factors and ensures electrical protection.
- Sheath: To enhance durability, silicone cables may also feature an outer sheath made of silicone rubber or another protective material.
Properties of Silicone Cable
Due to the properties of silicone rubber, silicone cables exhibit the following qualities.
| Key Property | Description |
| High Flame Retardancy | Silicone cables are not easy to burn and meet the flame test FT2 standard, reducing safety hazards and ensuring safer use in products and equipment. |
| Temperature Resistance | They maintain stable physical properties in extreme temperatures, remaining flexible from -76℉ to 392℉ (-60℃ to 200℃) and ensuring reliable performance in various conditions. |
| Flexibility | Silicone cables exhibit extreme flexibility, allowing them to bend without breaking. This makes them ideal for applications requiring movement, such as in machines or robotics. |
| Chemical Resistance | Resistant to many chemicals, oils, and solvents, silicone cables are suitable for industrial environments where contact with various substances occurs. |
| UV Resistance & Waterproof | UV-resistant and waterproof, silicone cables maintain stable physical and chemical properties even when exposed to harsh weather, prolonging product life. |
| Electrical Insulation | Silicone rubber provides excellent electrical insulation, making these cables suitable for high-voltage applications and reducing the risk of electrical failures. |
| Compression Resistance | Silicone cables retain their original shape under pressure, allowing for repeated bending and flexing without damage. |
| Low Toxin & Environmental Safety | Made from non-toxic materials, silicone cables do not contain heavy metals and do not pollute soil or water, making them safe for various applications, including food-related uses. |
Is Silicone Cable Better Than PVC Cable?
While silicone cables generally excel in many areas, PVC cables still offer advantages, particularly in terms of cost and comparable performance under simple and safe conditions, as long as they remain within their thermal limits.
| Feature | Silicone Cables | PVC Cables |
| Material Composition | Made of flexible silicone rubber | Made of hardened plastic |
| Temperature Resistance | Outstanding range: -90°C to 200°C+ | Resistant from -40°C to 105°C |
| Flexibility | Highly flexible and elastic | Less flexible |
| Maneuverability | Superior maneuverability for tight spaces | Limited maneuverability |
| Chemical Resistance | Resistant to oils and solvents | Less resistant to chemicals |
| Fire Resistance | Superior fire resistance, maintains circuit integrity | Lower fire resistance |
| Cost | Generally more expensive, price influenced by silicone shortages | Typically more affordable |
| Durability | Less hard-wearing, more susceptible to cuts and damage | More durable, harder to damage |
| Static Electricity | Generates static electricity, attracting dirt | Minimal static generation |
| Identification | Typically has a single insulation color, making it harder to spot damage | Easier to identify due to color options |
