Phenyl silicone rubber is a high-molecular-weight material with excellent ablation and radiation resistance, formed through the copolymerization and modification of monomers such as methylphenyl tricyclic bodies, methyl mixed cyclic bodies, and vinyl cyclic bodies.

The ablation resistance of phenyl silicone rubber is primarily due to the presence of phenyl groups. As the phenyl content increases, the ablation resistance of the silicone rubber gradually enhances, exhibiting remarkable stability in high-temperature and flame environments. Medium phenyl silicone rubber (with a phenyl content of 15-25%) can self-extinguish once ignited, making it an important choice for fire safety materials.

Simultaneously, phenyl silicone rubber possesses outstanding radiation resistance. High phenyl silicone rubber (with a phenyl content above 30%) maintains a stable molecular structure when exposed to radiation, resistant to degradation or crosslinking reactions, thereby extending the material's service life. This characteristic broadens its application prospects in radiation environments such as nuclear power plants, reactors, and radioactive wastewater treatment plants.

In addition to ablation and radiation resistance, phenyl silicone rubber also exhibits good weatherability and aging resistance. However, it should be noted that the double bonds in the phenyl structure are susceptible to oxidation reactions under ultraviolet radiation, leading to material aging and cracking. Therefore, in outdoor or long-term sunlight exposure applications, appropriate protective measures are needed to extend the material's service life.

In summary, phenyl silicone rubber plays a significant role in fire safety, nuclear energy, and military fields due to its excellent ablation and radiation resistance, as well as its good weatherability and aging resistance.
