Used for aerospace material of phenyl silicone rubber with good resistance to radiation degradability, excellent ozone resistance, excellent thermal circulation resistance obvious advantages, because it can withstand extreme temperature in space, and can at very low temperatures (other materials can harden and rupture) maintain good flexibility, and its features of elastomer inhibits launch the adverse effects of vibration. And performance changes encountered in space flight, such as temperature changes will lead to a surface shrinkage or hinder the propagation of electromagnetic waves and subatomic particles, and phenyl silicone rubber has good resistance to high and low temperature performance will solve this problem.

Although radiation in space can cause changes in the properties of space materials similar to thermal aging, some special silicone materials, such as phenyl silicone rubber, have excellent radiation resistance, which is suitable for use under radiation conditions and still maintain good mechanical properties. ‍
