# Liquid Silicone Rubber Seal For Avionics (Aerospace Avionics Equipment Sealing Rings)
Liquid Silicone Rubber (LSR) seals for avionics equipment are high-performance custom-molded sealing components designed and manufactured by 橡楚（湖北）橡胶有限公司 to meet the demanding operating requirements of modern aerospace electronic systems. Engineered from high-purity liquid silicone rubber, these seals deliver reliable long-term sealing performance across extreme temperature fluctuations, vibration cycles, and atmospheric exposure common in commercial, military, and general aviation applications.
Located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, our production facility specializes in custom LSR products, with dedicated process control for aerospace-grade sealing components. Our avionics LSR seals address core challenges faced by avionics system integrators: preventing moisture, dust, fuel vapor, and hydraulic fluid ingress while maintaining electrical insulation properties and mechanical resilience over the service life of aircraft electronic systems. Unlike generic rubber seals, our LSR avionics seals are formulated to retain elasticity and sealing force after thousands of hours of thermal cycling, resisting permanent compression set that causes premature seal failure in critical avionics components.
Our avionics LSR seals are manufactured from addition-cure liquid silicone rubber formulated specifically for aerospace electronic applications. Key material properties are outlined below:
Our liquid injection molding (LIM) process for avionics seals adheres to the following controlled manufacturing parameters:
Unlike organic rubber materials that degrade or harden at extreme low or high temperatures, our platinum-cured LSR retains consistent elasticity and sealing force across the full -60°C to +200°C operating range common in aircraft avionics bays. The material resists degradation from ozone, UV radiation, and atmospheric aging, with no significant change in hardness or compression set after 1000 hours of accelerated aging testing, ensuring long-term reliability in unconditioned avionics compartments.
Our avionics-grade LSR formulation produces seals with extremely low volatile content, eliminating the risk of outgassing that can contaminate sensitive optical sensors, connector pins, and electronic circuit boards. The platinum-cure process produces no corrosive byproducts, so the seal will not cause corrosion of metal components or degrade insulating materials in avionics assemblies over time. This meets the strict low-outgassing requirements for sealed electronic enclosures in aircraft.
Using liquid injection molding (LIM) technology, we can produce avionics seals in custom sizes and complex cross-sections with tight tolerances to fit a wide range of avionics components, from small connector seals to large equipment enclosure gaskets. Our production process ensures consistent part-to-part uniformity for high-volume orders, with no flash or blemishes that could compromise sealing performance.
All our avionics LSR seals are formulated to meet FAR 25.853 flammability requirements for aircraft interior components, with low smoke emission and no halogenated additives that would produce toxic fumes in the event of a fire. This makes our seals suitable for use in both cabin and airframe-mounted avionics systems.
Our Liquid Silicone Rubber Seals for Avionics are designed for use in a wide range of aircraft avionics and related aerospace applications, including:
Choosing the correct hardness for your avionics seal depends on the application and assembly requirements:
All our avionics LSR seals are custom-manufactured to match your component's dimensional requirements. We support:
We offer two standard material grades for avionics LSR seals:
橡楚（湖北）橡胶有限公司 maintains a full quality management system certified to ISO 9001, with rigorous quality control processes implemented at every stage of production, from raw material incoming inspection to final part testing before shipment. Each batch of avionics LSR seals undergoes dimensional inspection, visual inspection for molding defects, and verification of key material properties (hardness, compression set, volatile content) to ensure compliance with our specifications and your requirements.
We maintain full batch traceability for all products, with raw material lot records and production documentation retained for the lifetime of the product. For customers requiring additional testing or documentation, we can provide material test reports (MTRs) and process certification to support your system qualification requirements.
