Hydroxy phenyl silicone rubber has recently made significant technological progress in the specialty sealing materials sector. By introducing active hydroxyl functional groups into the molecular structure of phenyl silicone rubber, this material successfully enhances reactivity and bonding performance, providing innovative solutions for sealing applications in high-end fields such as aerospace and nuclear energy equipment.
Research data shows that while maintaining the excellent temperature resistance (-100℃ to 250℃) and radiation resistance (1×10⁷ Gy) of phenyl silicone rubber, hydroxy phenyl silicone rubber achieves tensile strength of 6.5-8.5 MPa and elongation at break exceeding 350%. After 500 hours of aging tests at 200℃, the material retains over 85% of its performance. Its unique chemical structure enables excellent bonding performance to various substrates including metals and ceramics.
In the aerospace sector, as a base polymer for high-performance RTV sealants, the material has been successfully applied in critical areas such as spacecraft window sealing and instrument module bonding. Measurement data from a certain satellite model indicates that seals prepared using this material show less than 15% performance degradation after three years of orbital operation. In the nuclear energy equipment field, its exceptional radiation resistance makes it a key material for nuclear power plant instrument seals and radiation environment protection.
With the rapid development of deep space exploration and new energy technologies, important progress has also been made in modification research of hydroxy phenyl silicone rubber. New-generation products demonstrate further improved processing characteristics and environmental adaptability while maintaining excellent performance. Industry experts note that this material's technological breakthrough will provide crucial material support for the innovative development of China's high-end equipment manufacturing industry.
