In many industries, the performance of materials is severely tested in extreme environment operations. However, silicone rubber, with its unique molecular structure and physical - chemical properties, shows extraordinary adaptability, and its applications in such environments are constantly expanding.

In high - temperature environments, silicone rubber is a top performer. Its main chain is composed of silicon - oxygen bonds (Si - O) with high bond energy, endowing the material with excellent thermal stability. In scenarios such as the sealing of high - temperature components in aircraft engines and the heat - dissipation modules of electronic devices, silicone rubber seals and thermal conductive pads can maintain elasticity and functionality for a long time at temperatures as high as 200 °C or even higher. Taking aircraft engines as an example, the seals around the combustion chamber need to withstand the impact of high - temperature gas. Silicone rubber seals can not only effectively block gas leakage but also, with their good flexibility, adapt to the thermal expansion and contraction of components during the thermal cycle, ensuring the stable operation of the engine. In electronic devices, as the performance of chips improves, the heat - generation problem becomes more prominent. Silicone rubber thermal conductive pads can efficiently transfer heat and will not experience performance degradation at high temperatures, ensuring the stable operation of electronic devices under high - temperature working conditions.
Low - temperature environments are also no challenge for silicone rubber. Even in extremely cold conditions of tens of degrees below zero, such as in polar scientific research equipment and low - temperature refrigerated transportation equipment, silicone rubber can still maintain good elasticity and toughness. In the polar regions, the sealing of outdoor equipment faces the challenge of extremely low temperatures. Ordinary rubber materials will become brittle and lose their sealing effect, while silicone rubber seals can maintain a tight fit, preventing the intrusion of water vapor, dust, etc., and protecting the precision components inside the equipment. In low - temperature refrigerated transportation, silicone rubber is used for the sealing and shock absorption of refrigeration equipment, ensuring the stable operation of the cold - chain system and the quality and safety of transported goods.
In high - radiation environments, such as in nuclear power plants, space exploration and other fields, silicone rubber also performs outstandingly. Its chemical stability gives it a certain resistance to radiation and can, to a certain extent, resist the damage of rays to the molecular chain. In nuclear power plants, silicone rubber materials are used for the insulation and sealing of some equipment, which can operate reliably for a long time in a high - radiation environment, ensuring the safety and stability of the nuclear power plant. In the space environment, silicone rubber is selected for the protective components and sealing materials of satellites, probes, etc., which can effectively resist cosmic ray radiation, extend the service life of the equipment, and ensure the smooth implementation of space missions.
