Phenyl silicone rubber, a high-performance silicone rubber material, has demonstrated its unique advantages in various fields in recent years. By introducing methylphenyl siloxane or diphenyl siloxane units into the molecular chain of methyl vinyl silicone rubber, phenyl silicone rubber not only inherits the excellent properties of methyl vinyl silicone rubber, such as low compression set, wide operating temperature range, oxidation resistance, weather resistance, shock absorption, moisture resistance, and good electrical insulation, but also possesses remarkable low-temperature resistance, ablation resistance, and radiation resistance.

Based on the phenyl content, phenyl silicone rubber can be classified into low-phenyl (5% to 15%), medium-phenyl (15% to 25%), and high-phenyl (above 30%) types. Low-phenyl silicone rubber maintains flexibility and elasticity even at extremely low temperatures (-115°C), making it ideal for manufacturing low-temperature-resistant components. Medium-phenyl silicone rubber exhibits outstanding ablation and flame resistance, capable of self-extinguishing upon ignition. High-phenyl silicone rubber, on the other hand, boasts excellent radiation resistance, making it widely used in aerospace and military industries.

Phenyl silicone rubber finds applications across various sectors, including the automotive, petrochemical, aerospace, and military industries. In the automotive sector, it is used for seals, oil seals, diaphragms, and ducts. In aerospace, it is employed in fuel- and lubricant-resistant seals and contacts. Additionally, its superior electrical insulation properties make it a popular choice in the power and electronic industries.
