The phenyl content in phenyl raw rubber has a significant impact on its application. Raw rubber with different phenyl content has its own performance and is suitable for different fields. The specific analysis is as follows：


Low phenyl raw rubber (phenyl content 5%~15%)
Low-phenyl raw rubber has excellent low temperature resistance as its core advantage.When the molar fraction of phenyl is 0.05~0.10, the hardening temperature can be reduced to -115℃, and the soft elasticity can still be maintained at -100℃. It is one of the best varieties of rubber with medium and low temperature performance.This characteristic makes it an ideal material for ultra-low temperature environments. For example, in the aerospace field, it can be used to manufacture sealing rings, gaskets and other components to ensure that the sealing performance can be maintained at extremely low temperatures. In the field of electronic appliances, it can produce low-temperature resistant pipe and cable coating materials to ensure the stable operation of equipment in low-temperature environments.In addition, low-phenyl raw rubber also has high damping characteristics, which is suitable for scenes that require damping and shockproof, such as shockproof bases for precision instruments.


Medium phenyl raw rubber (phenyl content 15%~25%)
Medium-phenyl raw rubber has outstanding performance in terms of flame resistance and damping properties.The increase in phenyl content enhances the ablation resistance of rubber and makes it self-extinguishing. Once it catches fire, it can be quickly extinguished. This characteristic makes it widely used in the fields of electrical and electronic engineering and aerospace.For example, in the fields of machinery and electronics, medium-phenyl raw rubber can be used to manufacture sealing materials that are resistant to high and low temperatures, effectively waterproof, moisture-proof and provide insulation protection; in the aerospace field, its flame-resistant properties can meet the high requirements of aircraft for fire safety.In addition, the physiological inertness of medium-phenyl raw rubber makes it suitable for the field of medicine and health, such as as a sealing material for blood refrigeration or medical pipes to ensure safety when in contact with the human body.


High phenyl raw rubber (phenyl content of more than 30%)
High-phenyl raw rubber has excellent radiation resistance and ablation resistance as its core advantages.In a high-radiation environment, the rigidity of its molecular chain increases, which can effectively resist radiation damage and maintain material stability; at the same time, its high temperature resistance is excellent, and it is suitable for the manufacture of sealing materials and molded products with special needs.For example, in the nuclear industry, high-phenyl raw rubber can be used to manufacture radiation-resistant seals and protective materials; in the aerospace field, its high temperature resistance and radiation resistance characteristics can meet the requirements of aircraft adaptability to extreme environments.In addition, high-phenyl raw rubber also has the excellent characteristics of small compression deformation and resistance to saturated vapor pressure, which is suitable for sealing applications in high-pressure environments.
