# LSR Gasket For Aircraft Electronic Compartment
*Manufactured by 橡楚(湖北)橡胶有限公司*
---
LSR Gasket for Aircraft Electronic Compartment is a custom-molded liquid silicone rubber sealing component engineered specifically to meet the demanding environmental and performance requirements of aircraft avionics compartments. Designed to protect sensitive on-board electronic systems from moisture, dust, vibration, and extreme temperature fluctuations, this product leverages the inherent advantages of high-purity liquid silicone rubber to deliver reliable long-term performance in commercial, general aviation, and military aircraft applications.
At 橡楚(湖北)橡胶有限公司, we formulate and mold these LSR gaskets in our production facility 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, with strict process control aligned with our quality management system standards. Each gasket is manufactured to meet tight dimensional tolerances, ensuring a consistent, precision fit for electronic compartment enclosure assemblies. Unlike traditional organic rubber gaskets, our LSR gaskets resist thermal degradation, ozone exposure, and aging in high-altitude operating environments, maintaining sealing integrity over decades of service life.
This product is suitable for both original equipment manufacturing (OEM) assembly and aftermarket replacement of aircraft electronic compartment gaskets. It can be custom cut or molded to match any enclosure geometry, from small modular avionics boxes to large bulk electronic compartment panels.

Our aircraft electronic compartment gaskets are manufactured from 100% pure, high-molecular-weight platinum-cured liquid silicone rubber, with no added fillers that compromise performance. Key material properties are listed below:
All performance values are tested per ASTM D2000 standard for rubber products:
All our LSR gaskets are produced via precision liquid injection molding (LIM) or compression molding, followed by post-curing to eliminate residual volatiles:

Aircraft electronic compartments operate in conditions that range from freezing high-altitude temperatures to heat generated by on-board avionics systems. Our LSR gaskets maintain consistent elasticity and sealing force across a -60°C to +200°C temperature range, far outperforming organic rubber alternatives that become brittle at low temperatures or soften and degrade at high temperatures. The low water absorption and inherent hydrophobicity of LSR prevent moisture ingress that can cause short circuits, corrosion, or signal interference in sensitive electronic equipment.
Aircraft structures are exposed to constant vibration from engines, aerodynamic turbulence, and landing gear operation. Liquid silicone rubber has natural damping properties that absorb vibration, reducing stress on both the sealing joint and electronic components. Additionally, LSR is resistant to ozone, UV radiation, aircraft hydraulic fluid, jet fuel vapors, and common cleaning chemicals, so it does not crack, shrink, or degrade over decades of service. This extends gasket replacement intervals, reduces maintenance costs for aircraft operators.
We produce LSR gaskets to match custom design requirements for any aircraft electronic compartment enclosure. Whether you need a simple rectangular gasket for a small avionics unit or a complex contoured gasket for a large bulkhead compartment, our precision injection molding process delivers tight dimensional tolerances and consistent quality. We can add self-adhesive backing for easy installation, or integrate mounting holes and notches to match your assembly design.
Our platinum-cured LSR formulation does not contain sulfur, low-molecular-weight siloxanes, or corrosive additives that can damage sensitive electronic components or react with aluminum and composite aircraft structures. This eliminates the risk of surface corrosion, contact contamination, or electrical leakage that can occur with lower-quality cured rubber gaskets.

LSR Gaskets for Aircraft Electronic Compartment are designed for use in a wide range of aircraft avionics and electronic system applications, including:
These gaskets are suitable for use in narrow-body, wide-body, regional commercial aircraft, general aviation aircraft, helicopters, and military training and transport aircraft, where reliable protection of electronic systems is critical to flight safety.

Choose the appropriate LSR hardness based on your application and sealing joint design:
We do not maintain a standard stock size for aircraft gaskets, as each application requires a custom fit matched to the enclosure geometry. We can manufacture gaskets up to 1200 mm x 800 mm in a single piece, and can produce multi-piece gasket assemblies for larger compartments if required. All gaskets are produced per customer-provided CAD drawings or sample measurements.
We offer two standard material grades to meet different application requirements:

At 橡楚(湖北)橡胶有限公司, all production processes are managed under our ISO 9001 certified quality management system, from raw material incoming inspection to final product shipment. Every batch of LSR material is tested for physical and mechanical properties before production, and each finished gasket undergoes 100% dimensional inspection and visual quality check to ensure compliance with customer requirements.
We maintain full production traceability for every gasket order, with records of raw material batches, production parameters, and inspection results retained for future reference. For customers requiring additional testing, we can provide material test reports (MTRs) per your project requirements.
