Methylphenyl silicone rubber is a specialized polymer material, essentially a large molecule of methylphenyl silicone oil. Its molecular structure contains numerous phenyl groups, which not only endow it with the high-temperature resistance and excellent dielectric properties typical of standard methyl silicone rubber but also provide enhanced radiation resistance and ablation resistance. In addition, it boasts superior physical and mechanical properties, along with outstanding high- and low-temperature performance. Depending on the phenyl content, methylphenyl silicone rubber is available in low, medium, and high phenyl types, each tailored to specific application needs.

This material is widely used in industries such as aerospace, electronics, machinery, and chemicals. It is ideal for manufacturing sealing and insulation materials capable of withstanding extreme temperatures while maintaining stable performance over long periods. Due to its unique high-temperature and ablation resistance, it is frequently employed in the production of radiation-resistant materials and molded parts to meet the demanding requirements of specialized industries.

Methylphenyl silicone rubber is insoluble in water but soluble in organic solvents like toluene, making it suitable for use in certain manufacturing processes. It is available in packaging options of 1.25 kg plastic containers or 200 kg steel drums, and should be stored in a well-ventilated, dry warehouse to maintain its stability. Classified as a non-hazardous material for transport, it has a shelf life of up to two years, offering high safety and ease of handling during storage and transportation.
