Phenyl silicone rubber used in aerospace materials has good resistance to radiation degradation, excellent ozone resistance, and excellent resistance to thermal cycling. It has obvious advantages because it can withstand the extreme temperatures in space and can operate at very low temperatures. It remains flexible at temperatures where other materials would harden and crack, and its elastomeric properties suppress the unwanted effects of emitted vibrations. In addition, performance changes encountered during space flight, such as temperature changes, will cause a surface to shrink or hinder the propagation of electromagnetic waves and subatomic particles. Phenyl silicone rubber has good high and low temperature resistance and can well resolve this problem.

Although radiation in space will 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 and are suitable for use under radiation conditions and can still Maintain good mechanical properties. ‍
