Phenyl silicone rubber used in aerospace materials has the obvious advantage of good resistance to radiation degradation · excellent ozone resistance · excellent thermal cycling resistance because it can withstand extreme temperatures in space and maintain good flexibility at very low temperatures (other materials will harden and crack). And its elastomeric properties can suppress the adverse effects of launch vibration. And the performance changes encountered in space flight, such as temperature changes, can cause a surface to shrink or hinder electromagnetic waves and subatomic particles from propagating, and the good resistance to high and low temperatures of phenyl silicone rubber will be a good solution to this problem.


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