Aerospace rubber supply is essential for the aviation, space, and defence industries, providing high-performance materials and components for sealing, insulation, vibration control, and fuel system applications. At Delta Rubber Limited, we supply a range of specialist rubber materials and precision-engineered rubber products designed to perform in extreme aerospace environments.

Materials such as Viton, Fluorosilicone, and Silicone are widely used due to their exceptional heat resistance, chemical compatibility, and durability, while Neoprene and EPDM offer excellent weather resistance and mechanical strength. These materials are used in critical aerospace applications, from fuel system seals to thermal insulation components.

In an industry where safety, reliability, and compliance are vital, sourcing the right rubber materials and products is crucial. This guide explores the key materials, industry standards, and common aerospace rubber applications, helping you find the right solutions for your requirements.

 

Rubber Materials for the Aerospace Industry

The aerospace industry relies on high-performance rubber materials that can withstand extreme temperatures, harsh chemicals, and demanding operating conditions. At Delta Rubber Limited, we supply a range of specialist aerospace-grade rubber materials designed for sealing, insulation, vibration damping, and fluid resistance.

The aerospace sector requires high-performance rubber materials capable of withstanding extreme conditions, including high temperatures, fuel exposure, and mechanical stress. At Delta Rubber Limited, we supply a range of specialist aerospace rubber materials, each suited to different applications within the industry.

Viton Fluoroelastomer & Viton Sponge

Viton is a high-performance fluoroelastomer widely used in aerospace due to its exceptional resistance to fuels, oils, and high temperatures. It is commonly found in fuel system seals, gaskets, and O-rings where prolonged exposure to jet fuels, hydraulic fluids, and lubricants demands long-lasting durability. Viton sponge provides the same chemical and heat resistance but with a compressible, lightweight structure, making it ideal for sealing applications requiring flexibility and cushioning.

Fluorosilicone

Fluorosilicone is a highly durable elastomer designed to perform in extreme temperatures and harsh chemical environments. It offers the flexibility of standard silicone but with added resistance to fuels, oils, and solvents, making it suitable for aviation fuel systems, seals, and gaskets in critical aerospace applications. Fluorosilicone components are widely used in aircraft engines, fluid transfer systems, and sealing solutions where chemical exposure is a key concern.

Neoprene (BS Standard & Commercial Grades)

Neoprene is valued in aerospace for its versatile mechanical properties and resistance to weathering, oils, and moderate chemicals. We supply both British Standard BS Neoprene and commercial-grade neoprene, ensuring compliance with aerospace requirements where needed. Flame retardant neoprene is also available, making it suitable for insulation, protective covers, vibration damping, and sealing applications in aircraft and ground support equipment.

Silicone (Standard, Flame Retardant & Electrically Conductive)

Silicone is a high-temperature-resistant elastomer commonly used in aerospace applications that require thermal stability, flexibility, and electrical insulation. We offer standard silicone, flame-retardant silicone for fire-critical applications, and electrically conductive silicone used in EMI/RFI shielding. Silicone is widely applied in sealing, gasketing, and thermal insulation for both aircraft and spacecraft due to its ability to perform in extreme environmental conditions.

 

Common Aerospace Rubber Products

Aerospace rubber products are designed to meet the demanding needs of the industry, offering solutions for sealing, insulation, and vibration control. These products are used in various components of aircraft, spacecraft, and other aerospace systems to ensure safe, efficient, and reliable performance under challenging conditions. Some of the most common aerospace rubber products include:

  • Gaskets: Gaskets create reliable seals between surfaces, preventing leaks in critical systems like fuel, hydraulic, and engine systems. Aerospace-grade gaskets are designed to withstand extreme temperatures and pressures, providing long-term performance in high-stress environments.
  • O-Rings: O-rings are used to seal joints and connections in a wide range of aerospace applications. Their reliable sealing properties are vital for systems such as fuel tanks, hydraulic lines, and pressure vessels, where they prevent leaks and ensure system integrity.
  • Vibration Dampeners: These rubber components reduce vibrations and absorb shock, protecting sensitive equipment from the damaging effects of oscillations and movement. They are commonly found in engine mounts, landing gear, and structural components, minimising wear and tear on critical parts.
  • Fuel Hoses and Tubing: Made from high-performance rubber materials like Viton and Fluorosilicone, fuel hoses and tubing provide secure and durable pathways for fuel transfer in both aviation and spacecraft applications, even under high pressure and extreme temperatures.
  • Thermal Insulation Components: Aerospace rubber products used for thermal insulation help to protect components from excessive heat. Materials like silicone and fluorosilicone are commonly used to safeguard sensitive areas, such as engines and fuel systems, from temperature extremes.

 

Applications of Aerospace Rubber Components

Aerospace rubber components play a crucial role across a wide range of applications in the aviation, spacecraft, military, and maintenance, repair, and overhaul (MRO) industries. These components are designed to perform under extreme conditions, ensuring safety, efficiency, and reliability. Below are some key applications:

Aviation / Aircraft

In the aviation industry, rubber components are used throughout the aircraft for sealing, insulation, and vibration control. O-rings, gaskets, fuel hoses, and vibration dampeners are commonly used in critical systems such as engines, fuel tanks, and hydraulic lines. Rubber materials like Viton and Neoprene ensure the integrity of these systems while withstanding the high temperatures, pressures, and mechanical stresses encountered during flight.

Spacecraft / Satellite

For spacecraft and satellite applications, rubber components provide crucial sealing, thermal insulation, and vibration dampening. Fluorosilicone and silicone are used for their excellent resistance to extreme temperatures and space-related conditions, including exposure to chemicals and radiation. Rubber products are used in fuel systems, connectors, thermal protection, and sealing systems to ensure reliable performance in harsh space environments.

Military and Defence

In the military and defense sector, rubber components are used in various applications, from seals and gaskets to vibration isolators in aircraft, submarines, and military vehicles. These products must meet strict reliability standards, often requiring custom specifications for extreme conditions, including high-stress environments, exposure to chemicals, and fluctuating temperatures. Delta Rubber Limited works closely with MOD companies, ensuring discretion and confidentiality for sensitive projects.

Maintenance, Repair, and Overhaul (MRO)

MRO operations rely on high-quality rubber components to keep aerospace systems running smoothly. From replacement seals and gaskets to custom rubber parts for repairs, MRO applications require fast turnaround times and reliable materials. Common products used in this sector include gaskets, O-rings, rubber sheet/strip, and vibration dampeners. These components help maintain the performance and safety of ageing equipment and ensure continued operation of aerospace systems.
