In the journey of human exploration of the universe, silicone rubber, with its characteristics of resistance to extreme environments and high reliability, has become an indispensable "space material" for spacecraft. From satellite components to astronauts' equipment, it is breaking through the limits of the universe with its "flexibility".

The "Interstellar Armor" of Satellites and Probes

Solar Panel Encapsulation: The silicone rubber film can withstand extreme temperature differences ranging from -200°C to 150°C, protecting the solar cells from damage caused by cosmic rays.

Thermal Control Coating: The silicone rubber coating with added ceramic particles maintains a constant temperature inside the satellite through radiative heat dissipation.

Sealed Connectors: The silicone rubber sealing ring maintains its elasticity in a vacuum environment, preventing air leakage in the spacecraft.

Case: The landing buffer device of China's Tianwen-1 Mars probe uses silicone rubber materials, which still maintain good buffering performance in an environment of -130°C on the surface of Mars.

The "Life Support" for Astronauts' Equipment

Extravehicular Spacesuits: The silicone rubber joint seals ensure stable air pressure, and the fingertips of the gloves use conductive silicone rubber to enable the operation of extravehicular equipment.

Emergency Breathing Apparatus: The silicone rubber breathing valve precisely controls the airflow in a weightless state, ensuring the safe return of astronauts.

Radiation Protection Layer: The silicone rubber apron containing lead elements effectively shields the reproductive system from cosmic radiation damage.

The "Flexible Infrastructure" of Space Stations

Deployable Structures: The silicone rubber spring system helps the solar panels deploy in space, and the contracted volume is only 1/10 of the deployed state.

Water Recycling System: The silicone rubber membrane separates the water in urine, with a recovery rate of up to 95%, supporting long-term space habitation.

In-cabin Vibration Damping: The silicone rubber vibration isolators reduce the vibration transmission during the operation of the space station's robotic arm.

Future Trend: In the "Space Planting Cabin" developed by NASA, the silicone rubber matrix simulates lunar soil, supporting the growth of plants in a microgravity environment.
