The space industry is constantly pushing the boundaries of innovation, developing advanced materials to enhance spacecraft performance, fuel efficiency, and durability. With extreme environmental conditions in space, the materials used must withstand intense radiation, temperature fluctuations, and mechanical stress.
RD Rubber Technology Corporation plays a crucial role in this sector, providing precision-engineered rubber sealing solutions tailored for aerospace applications. As a trusted manufacturing partner in the industry, we adhere to the strict requirements of government agencies and contracts, including the United States Space Force (USSF).

Key Materials for Satellites and Spacecraft
Selecting the right space industry materials is critical to the success of any mission. These materials must endure the rigors of launch, operation in the vacuum of space, prolonged exposure to cosmic radiation, and the extreme temperatures of space travel and reentry into the Earth’s atmosphere. Some of the most commonly used elastomers in the space industry include:
- Neoprene. This is a versatile elastomer with high resilience, low compression set, and moderate resistance to oil, ozone, and water. It functions within a temperature range of -65°F to 260°F, making it ideal for sealing applications in dynamic environments. It’s not suitable for exposure to phosphate esters, ketones, or brake fluids due to its limited chemical resistance.
- EPDM (Ethylene Propylene Diene Monomer). Known for its excellent weatherability and low gas permeability, EPDM withstands temperatures between -60°F and 280°F. It provides exceptional resistance to ozone, water, and brake fluids—ideal for sealing and insulation applications in extreme environments. It has limited resistance to petroleum oils and diester lubricants, restricting its use in hydrocarbon-based systems.
- Silicone. With the broadest operating temperature range of -150°F to 500°F, silicone excels in high-temperature stability and resistance to brake fluids and high aniline point oils. Its flexibility and low toxicity make it a preferred choice for aerospace applications requiring thermal insulation and sealing. However, its relatively poor tensile strength and tear resistance can limit its mechanical durability in certain high-stress environments.
