Phenyl silicone rubber introduces phenyl side groups onto the siloxane backbone, significantly enhancing radiation resistance and ultra-low temperature performance. Its glass transition temperature can drop as low as -120°C, maintaining elasticity even in liquid nitrogen, while offering excellent ozone and UV resistance. Widely used in spacecraft seals, nuclear power cable insulation, and polar expedition equipment, it is a reliable material for deep space radiation and extreme cold environments.
