In the scientific research station on the Antarctic ice sheet, the thermometer points to -80℃, but the sealing ring in the equipment cabin still rotates flexibly; at the rocket launch base, the thermal insulation pad around the engine nozzle is resisting the high temperature of thousands of degrees Celsius; in the nuclear industry laboratory, the pipe interface in the radiation environment is always kept sealed - in these extreme scenes, there is a "material all-rounder" that is silently sticking to it, and it is RTV phenyl silicone rubber.



This seemingly ordinary elastic material actually has a lot of "hard skills". Let's start with its "antifreeze skills". Common rubber will become brittle and crack at minus dozens of degrees Celsius, but RTV phenyl silicone rubber can maintain its elasticity in an ultra-low temperature environment of -120℃, which is equivalent to being nearly 30℃ lower than the most extreme low temperature in Antarctica (about -94.2℃). It can still be as flexible as a young bud in early spring. This means that in drilling equipment for polar scientific research, it can be used as a sealing gasket to prevent leakage of cryogenic liquids; in the instrument cabin of deep space exploration satellites, it can keep the line interface stably connected in the extreme cold of interstellar space;Even in ultra-low temperature laboratories, pipes made of it can safely transport refrigerants such as liquid nitrogen, fundamentally avoiding the dangers of ordinary materials being frozen and cracked.

It can withstand severe cold and even more so "fire". When an aircraft passes through the atmosphere, the surface temperature will soar to thousands of degrees Celsius. At this time, the insulation material covering the outside depends entirely on RTV phenyl silicone rubber to "stabilize the situation". Its inherent ablation resistance can act like an invisible protective shield, slowly carbonizing under high temperature, consuming heat through the material's own sacrifice to protect internal equipment from damage. In the industrial field, the sealing rings around automobile engines and the insulation pads of boiler pipes can work in an environment above 200°C for a long time as long as it is added with heat-resistant additives. Even after repeated alternation of hot and cold, it will not harden or break.

Even more amazing is its "anti-radiation shield" capability. In an environment with radiation, the molecular structure of ordinary materials is easily destroyed, resulting in a sharp drop in performance, but RTV phenyl silicone rubber can resist the "erosion" of radiation. This makes it an ideal choice in the nuclear industry: the anti-radiation coating applied to the surface of the equipment can reduce the impact of radiation on the instrument; the sealing ring used for the pipe interface can maintain sealing performance even in a radiation environment for a long time, adding an important link to safe operation.
