In the electronics industry, material stability and insulation properties are critical. Phenyl silicone rubber, with excellent electrical insulation and radiation resistance, is widely used in high-performance electronic components and specialty cables. Its unique phenyl structure enhances thermal resistance and aging stability, ensuring reliable dielectric performance even in prolonged high-temperature or radiation conditions. This makes it essential for nuclear power equipment, military electronics, and high-frequency communication systems. With the expansion of 5G and next-generation communication technologies, the demand for phenyl silicone rubber is expected to rise steadily.
