Key Features and Benefits
Temperature Resistance
Performs well across a broad temperature range, typically from -100°F to +500°F (-73°C to +260°C).
Chemical Resistance
Resistant to a wide range of chemicals and solvents.
Weather Resistance
Excellent resistance to ozone, UV light, and other environmental conditions.
Low Water Absorption
Due to the closed-cell structure, it does not absorb water, making it suitable for sealing and gasket applications.
Resilience and Flexibility
Retains its shape and properties under compression and after extended use.
Applications of the ASTM D1056 Soft Closed Cell Silicone Sponge
ASTM D1056 Soft Closed Cell Silicone Sponge is ideal for use in:

More Information on ASTM D1056
- FAR 25.853 is a regulation part of the Federal Aviation Regulations (FARs), addressing flammability requirements for materials used in constructing commercial aircraft.
- The regulation mandates that materials inside the aircraft cabin, such as seat cushions, wall panels, and flooring, must be flame-resistant and can withstand specific fire tests.
- It includes specific criteria and test methods for assessing the flammability of these materials, ensuring that they do not ignite and, if they do, then burn slowly and self-extinguish.
- Adherence to FAR 25.853, which focuses on improving passenger safety by reducing the risks connected with in-flight fires, is essential for aircraft certification.
