Rubber Products in the Aerospace Industry

The aerospace and aviation industry is one of the fastest growing industries on a global scale, affecting millions of people on a daily basis.

Reliable aircraft demands top tier components. These parts must have properties of high performance and endurance, since they will be exposed to a range of extreme weather conditions, such as excessively hot or cold temperatures, and different types of oils and gases. It is crucial that jets, commercial planes, and other aircraft can protect both passengers and cargo from the elements.

Many aerospace and aviation components are now being sourced from rubber. Rubber products are becoming more popular due to their durability under extreme environmental conditions and cost-effectiveness.

Rubber Designed for Flight

Rubber products are an excellent option for flight applications. Synthetic rubbers from various sources can withstand highly aggressive aerospace fluids, including:

  • Engine lubrication oils
  • Jet fuels
  • Hydraulic fluids
  • Oxidizers
  • Rocket propellants

Some of the common materials that engineers utilize for aerospace and aviation applications include:

  • Neoprene. This is a good general purpose elastomer that has many desirable characteristics. It has high resilience with low compression set and boasts moderate oil, ozone, and water resistance. It successfully operates within a temperature range of -65°F to 260°F. However, neoprene is not recommended for certain applications like phosphate esters, ketones, and brake fluids.
  • EPDM. Also known as Ethylene Propylene Diene Monomer, EPDM contains excellent weatherability properties and low gas permeability. It works within a temperature range of -60°F to 280°F. While it is highly resistant to ozone, water, brake fluids, and other substances, it has a low resistance threshold for petroleum oils and diester lubricants.
  • Silicone. Able to effectively operate in temperatures from -150° to 500°F, silicone boasts the greatest total temperature range of currently used elastomers. While it also has excellent resistance to a number of environmental conditions and outside substances, such as dry heat, brake fluids, and high aniline point oils, it is not an optimal solution for certain applications due to poor tensile strength and tear.

Rubber materials have an array of qualities that make them the perfect choice for aerospace and aviation applications. Some characteristics that stand out include:

  • A high endurance threshold under extreme stresses
  • Endurance under extreme temperatures
  • No need for lubrication between parts
  • Very little maintenance required, if any
  • Sound and shock absorption
  • Long life spans

Applications That Demand Rubber Products

Rubber products have become popular across a broad spectrum of industries. In the aerospace and aviation industry, they have delivered superior performance in applications, such as:

  • Thermal insulation
  • Window and door seals
  • HVAC seals and gaskets
  • LED lighting gaskets
  • Vent ducts
  • Vibration dampening
  • Instrument panel seals and engine gaskets
  • O-rings utilized in connectors, valves, and other applications
  • Hydraulic actuators
  • Bleed air valves and fittings
  • Firewall seals
  • T-seals
  • Bumpers
  • Hatch seals and covers
  • Rubber extrusions
  • Extruded tubing and seals
  • Protective boots and bellows
