Phenyl silicone rubber for aerospace materials has the obvious advantages of good radiation degradation resistance, excellent ozone resistance, excellent thermal cycling resistance, because it can withstand the extreme temperatures in space, and can maintain good flexibility at very low temperatures (other materials will harden and crack), and its elastomer properties can inhibit the adverse effects of emission vibration. And the performance changes encountered in space flight, such as temperature changes will cause a surface shrinkage or hinder the propagation of electromagnetic waves and subatomic particles, and phenyl silicone rubber has a good resistance to high and low temperatures will be a good solution to 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. ‍
