Rubber Materials for The Aerospace Industry

First, let’s have a look at some of the different types of rubber materials you can use for aerospace products:

  1. Nitrile Rubber (NBR): Many aerospace oil and fuel system components use NBR. This is because nitrile has excellent oil and fuel resistance properties.
  2. EPDM: This rubber material performs exceptionally well against ozone, weathering, and heat. Thus, it easily withstands harsh conditions in aerospace applications.
  3. Silicone: the engine gaskets and seals used in airplanes often use silicone rubber. Why? Because silicone incredibly resists heat and has a low compression set.
  4. Neoprene: whether its heat, chemicals, or ozone, neoprene withstands them all. Moreover, the material has a high demand for electrical and weather applications thanks to its insulating properties.
  5. Polyurethane: This material offers excellent durability. Also, it can withstand abrasions, making it a suitable choice for hoses and cables. 

Types of Aerospace Rubber Molding Methods

Different types of rubber molding processes help produce aerospace-custom molded rubber parts. These include:

Compression Molding

Compression molding requires a set amount of rubber. This rubber is then placed inside a heated mold. Moreover, the final shape derives from a combination of pressure alongside heat.

Transfer Molding

This method uses the pot and plunger mechanism. A set amount of uncured rubber goes into the pot, also known as the chamber. It is then transferred into a heated mold using a plunger. As a result, transfer molding helps create exact custom-molded parts.

Injection Molding

In this molding process, the manufacturer takes uncured rubber and injects it into a heated mold. Moreover, they also apply pressure which helps shape the rubber into the desired form. This molding technique helps create small rubber components for aerospace applications.

The Benefit of Using Molded Rubber Products for Aerospace

The most prominent benefits of custom-molded rubber parts in the aerospace industry include:

  1. Flexible: custom molded rubber offers excellent elastic properties. Hence, they become a suitable option for dynamic applications.
  2. Durable: rubber tends to withstand challenging conditions in the aerospace industry. This has mostly to do with the durability of vulcanized custom-molded rubber components.
  3. Versatile: rubber components also offer incredible versatility. This includes altering their shape, size, color, and even material. Moreover, you can also place customized orders as per need.
  4. Economical: rubber molded products are pretty cost-effective compared to alternate materials. Moreover, they also have a long shelf and service life. Hence, they reduce maintenance and replacement costs in the long run.

Molded Rubber Products Used In Aerospace

  • Seals: help prevent leaks in aerospace fuel and hydraulic systems.
  • Gaskets: help seal two surfaces tightly together, such as fuel tanks and joints.
  • O-rings: used in oil systems and fuel systems for sealing purposes.
  • Tubing: used for transfer purposes such as transferring fuel or oil from one component to another.
  • Bushings/Mounts: used for isolating vibrations and reducing noise
  • Diaphragms: helps control flow and pressure in fuel and oil systems.
