Aeronautics Performance Enhancements | Lightweight | Durability

We Commit to Quality : Our custom silicone seals are designed to meet the most severe conditions and reliability requirements of the aerospace industry.

Not only do our high performance seals excel in extreme temperatures and offer weather resistance for enhanced aeronautic performance, but thanks to their light weight they also reduce fuel consumption. And given, silicone is recognized as a non-toxic material with high durability, Covison seals ensure strict adherence to aerospace Fire, Smoke and Toxicity (FST) norms as well as offer minimal maintenance requirements.

Aerospace Industry Standards Compliance

Since security is crucial to the aerospace market, Saint-Gobain makes compliance a priority. Covison silicone seals meet all necessary tests and criteria and comply with national and international aerospace standards.

Examples of industry standards that our seals meet:

DIN standard
WL standard
AMS3302
AA59-588 series
Wide range of Airbus approved standards: AIMS, ABR, etc.

Co-Development

Our use of advanced technology enables us to deliver seals in various formulations, compounds and processes: extrusions, compression molding, injection moldings, reinforced composite moldings, or finishing processes such as self-adhesive.

Additionally, we utilize the innovative process of Finite Element Analysis (FEA) to anticipate seal behavior and detect potential problems before they occur.
