High Temperature Silicone Wire is designed for applications where durability, flexibility, and heat resistance are essential. With its silicone rubber insulation, this wire maintains excellent electrical performance under extreme temperature conditions — from -60°C to +200°C, and in some cases even higher.

high temperature silicone wire
It is widely used in industrial machinery, household appliances, automotive systems, lighting fixtures, and aerospace equipment, offering long-term reliability even in high-heat or cold environments.
Key Features
🔥 High Temperature Resistance: Operates continuously at -60°C to +200°C without insulation cracking or degradation.
⚡ Excellent Electrical Insulation: Silicone rubber provides superior dielectric strength and stable performance under voltage stress.
🧩 Outstanding Flexibility: Remains flexible even in sub-zero conditions — ideal for dynamic or tight-space wiring.
🧯 Flame Retardant and Non-Toxic: Silicone insulation is self-extinguishing and emits minimal smoke when exposed to fire.
🧲 Chemical and Weather Resistant: Resists oils, acids, UV radiation, and ozone exposure.
🧰 Durable Construction: Fine-stranded copper conductor ensures mechanical strength and low power loss.

Advantages of Silicone Over PVC Insulation
Feature | Silicone Wire | PVC Wire |
---|---|---|
Temperature Range | -60°C to +200°C | -20°C to +105°C |
Flexibility | Excellent | Limited at low temperature |
Chemical Resistance | High | Moderate |
Flame Resistance | Self-extinguishing | Standard |
Durability in Outdoor Use | Excellent (UV & ozone resistant) | Poor |
If your application requires flexibility, heat endurance, or stable performance under thermal cycling, silicone wire offers a superior solution compared to PVC or Teflon alternatives.
