Product Description

Product Description

Low-Density Silicone Foam Thermal Liner for Aerospace Applications

 

Foamed silicone is an advanced, lightweight, and porous elastomer derived from silicone rubber. It is specifically engineered to possess a unique cellular structure composed of numerous air or gas-filled pockets, which are evenly distributed throughout the material. This cellular architecture is typically achieved through the use of chemical foaming agents, mechanical aeration techniques, or the injection of gases during the vulcanization or curing process. The result is a soft, resilient foam matrix with low density that retains the core performance characteristics of solid silicone rubber, such as flexibility, chemical inertness, and long-term durability, while serving as an effective thermal liner for aerospace applications with enhanced cushioning properties.

Key Performance Characteristics

Foamed silicone exhibits excellent thermal insulation properties, primarily due to the entrapped air within its internal cells, which acts as a natural barrier against heat transfer-making it a high-performance thermal liner for aerospace applications. This allows it to effectively regulate temperature and protect sensitive aerospace components against extreme thermal fluctuations. It is capable of withstanding a broad temperature range, from as low as -60°C up to +200°C or higher, without significant degradation in physical or mechanical performance, ensuring reliable thermal liner functionality in the harsh thermal environments of aerospace operations.

In addition to its thermal stability, foamed silicone offers outstanding resistance to ultraviolet (UV) radiation, ozone, oxidation, and a wide range of chemicals-critical properties for aerospace applications exposed to extreme outer space or high-altitude conditions. This makes it highly suitable for long-term use in aerospace thermal liners, where material integrity under extreme environmental stress is paramount. Its superior compressibility and energy-absorbing properties, combined with low density, make it an ideal choice for vibration damping, shock absorption, and sealing solutions in sensitive aerospace assemblies, while maintaining efficient thermal insulation as a liner.

Foamed silicone is available in both open-cell and closed-cell configurations, allowing for application-specific customization as a low-density thermal liner for aerospace applications. Open-cell foam provides excellent breathability, while closed-cell foam delivers superior resistance to water, moisture, and other fluid ingress-making it ideal for thermal liner and sealing applications in aerospace systems where environmental protection and low-density performance are critical.

 

 

 

Key Features of Foamed Silicone Products

Foamed silicone is a specialized category of silicone elastomers, engineered with a cellular structure containing air or gas-filled pockets.
