Hydroxyphenyl silicone rubber is gaining traction in nuclear energy, aerospace, and military applications for its ability to maintain integrity under high heat and radiation. The phenyl structure grants superior thermal and oxidative resistance, while hydroxy end groups enable enhanced reactivity with fillers and crosslinking agents.

In sealing systems for reactor containment doors, high-temperature aerospace gaskets, and physics lab equipment, this material resists gamma and X-ray exposure while maintaining elasticity and tight seals. Its versatility supports compression molding, extrusion, and coating processes.

With increasing global demand for long-life, high-reliability sealing materials, hydroxyphenyl silicone rubber is poised to become a critical solution in the next generation of advanced engineering projects.
