While engineers will often discuss how various metals and composites are crucial for the integrity and overall functionality of an aircraft, many other materials also play large roles in standard operations and construction. Rubber in particular is a material that is beneficial to many applications due to its water resistance, heat resistance, strength, and resiliency. For aircraft in particular, rubber material components can be produced to act as adhesives, sealants, heat shields, and many other part types. In this blog, we will provide a brief overview of how various natural rubber and synthetic rubber materials are used in aircraft and how their characteristics benefit such applications.
