In the modern electronics and electrical industries, the development and application of conductive materials have been a driving force behind technological progress. Compared to traditional silicone products, conductive liquid silicone rubber holds overwhelming advantages in multiple aspects:
Traditional conductive materials like metal conductors offer good conductivity but suffer from issues such as corrosion susceptibility and heavy weight. In contrast, conductive liquid silicone rubber forms a three-dimensional conductive network by embedding conductive particles within a silicone rubber matrix. This ensures reliable conductivity while maintaining the material's inherent flexibility and elasticity.
Its volume resistivity can be adjusted over a wide range based on filler type and concentration. For example, silver-filled conductive silicone can achieve resistivity as low as 10⁻³ Ω·cm, nearing metallic conductivity levels. Moreover, its resistance variation remains below 5% within a temperature range of -50°C to 200°C, demonstrating strong stability even in harsh environments like high humidity, salt spray, and extreme temperatures.
Traditional conductive materials often lack flexibility and elasticity, whereas conductive liquid silicone rubber excels in these areas. It typically boasts a tensile strength of 1–5 MPa and an elongation at break of 200–500%, enduring over 100,000 bending cycles (radius ≤ 1mm) without cracking.
Additionally, it exhibits excellent chemical resistance, withstanding acids, alkalis, organic solvents, and biofluids. Some variants even meet ISO 10993 medical-grade certification, making them suitable for healthcare applications.
Traditional conductive materials face limitations in shaping complex geometries. Conductive liquid silicone rubber, however, offers superior flow properties, enabling injection molding, extrusion, compression molding, and other processing methods. This allows for the production of intricate and finely structured components, such as conductive buttons, rollers, and seals, with high efficiency and automation-friendly production, reducing manufacturing costs.
Unlike many conventional conductive materials, conductive liquid silicone rubber delivers outstanding high/low-temperature resistance and anti-aging properties. It maintains stable performance across an extreme temperature range of -70°C to 200°C, resisting degradation, cracking, or performance loss even after prolonged use, making it adaptable to diverse and demanding environments.
Combining multiple superior properties, conductive liquid silicone rubber not only ensures high conductivity but also retains the flexibility, elasticity, temperature resistance, and durability of silicone rubber. Its ease of processing further meets the diverse demands of various industries, including electronics, telecommunications, power, military, and aerospace, where it has become a mainstream material.
By outperforming traditional materials in conductivity, mechanical strength, processability, and environmental resilience, conductive liquid silicone rubber stands as the material of choice for next-generation applications.
