LegenDay Silicone Foam
The silicone foam is a type of synthetic rubber used in firestops, sheets, and gaskets. It is accessible in the cure, solid form, and single liquid components for installation fields. The silicone foam is manufactured through a casting process to ensure smooth skin on both sides. It is classified as open cell silicone foam, closed cell silicone foam, and expanded silicone foam.
In China, LegenDay is committed to supplying silicone foams with excellent performance properties, including high-temperature stability, low compression set, and low-temperature flexibility. We can guarantee that our silicone foam products are flame rated with FAR and UL 94. It also meets the requirements of environmental sealing like UL 508 and UL 50.

Our open cell silicone foam is widely utilized for dust sealing, cushioning, or light water sealing. These are available in different firmness.

LegenDay closed cell silicone is widely used for wash-down gaskets, outdoor gaskets, and resilient cushioning pads.

The expanded silicone foam is mostly used for high-temperature applications. It can provide excellent water and dust sealing.

LegenDay gasket silicone foam, with its excellent performance properties, is widely used in different industries that require long-term performance.

The insulation silicone foam tube has outstanding heat-resistant air aging performance, strong sealing, ozone resistance, and is moisture-proof.

LegenDay silicone foam sealing strip has outstanding properties, such as low and high-temperature resistance, fire-resistant, wear-resistant, etc.
Benefits of Silicone Foam

Our silicone foam can resist temperature variations, ranging from -67°F to 392°F (-55°C to 200°C).

LegenDay silicone foam provides excellent water sealing with respectively low compressive forces.

Both closed cell and open cell silicone foam is used for sealing dust with minimum compressive forces.

It provides good compression set resistance – the ability to recoil to the original thickness.
High Thermal Insulation
LegenDay silicone foam is a great thermal insulator for several reasons:
- Made from blown materials. It can guarantee that the cells resist heat transfer well.
- Our silicone foam has high heat resistance.
- Our silicone foam can withstand a compression set after heavy heat exposure.


Specifications of Silicone Foam Materials
Legenday manufactured silicone foams that meet UL standards, such as UL 157, UL 1572, UL 1571, UL 1570, UL 508, UL 50E, UL 50, UL 94 requirements.
Our silicone foams also meet ASTM D6576, AMS3195, AMS3196, MIL-R-6130 Type II, MIL-R-46089, and UL 94V-0 requirements.
Silicone Foam Benefits
