A specialty silicone rubber incorporating phenyl functional groups, Methyl Phenyl Vinyl Silicone Rubber, is emerging as a new favorite in the aerospace and high-end electronics sectors due to its exceptional resistance to extreme cold and radiation.

While conventional silicone rubber becomes brittle at very low temperatures, the phenyl ring structure introduced into its molecular chain effectively inhibits molecular chain crystallization at low temperatures. This allows it to maintain excellent flexibility and elasticity at temperatures as low as -100°C and beyond. This characteristic makes it the material of choice for seals and damping components in deep-space probes. Concurrently, its resistance to high-energy radiation far surpasses that of standard silicone rubber, making it suitable for components in satellites, space stations, and other radiative environments.

In the field of high-end electronics, this material is also used for chip carrier trays and the encapsulation of precision sensors. Its dimensional stability under rapid temperature fluctuations protects delicate electronic components, ensuring device reliability in complex environments and showcasing the immense potential of specialty polymer materials.
