Why Use Aviation Silicone

This synthetic rubber offers many outstanding properties that make it practical for aerospace environments. Aviation-grade silicone has excellent resistance to water, extreme temperatures, pressure fluctuations, shocks and chemicals. Certain forms of silicone form an airtight seal with electrical insulation to protect sensitive components. Silicone can be moulded to precise tolerances for gaskets and other parts or applied as a “quick repair” sealant to fix leaks and join materials.

Silicone has many uses in an aircraft, including sealing critical components in the engine, fuel system, landing gear, cockpit and cabin. It is also used to coat wiring and circuit boards, as well as a caulking material for filling larger gaps.

Aircraft Silicone from Silmid

We offer aerospace silicone in many forms, including fluids, greases, primers, moulding rubbers and encapsulants. Order silicone RTV which cures at room temperature for ease of application. Specialty aviation silicones such as resin, insulating wrap and peelable solder masks offer unique solutions for manufacturing needs. Use the filters to browse certain categories and find the information you need about each product such as curing time.

With the ability to quickly and accurately process small and large volume orders, Silmid serves businesses worldwide looking for aviation products that meet exact specifications. Customers who need a regular supply of aerospace silicones will get them with bulk discount pricing and automated inventory management.
