FAQ

What Temperature Range Can Silicone Foam Withstand?


Most silicone foam materials can operate continuously between -60°C and 250°C, making them suitable for electronics, battery systems, industrial equipment and high-temperature manufacturing applications.

Can SENMA provide custom thickness and hardness?

Yes. We support customized thickness, density, hardness, color and adhesive backing options.

What Is The Difference Between Silicone Foam And Silicone Sponge?

Silicone foam typically features a finer closed-cell structure, providing superior sealing and lower water absorption.
Silicone sponge is generally softer and more compressible, making it ideal for gasketing and cushioning applications.

Is Silicone Foam Waterproof?

Yes. Closed-cell silicone foam provides excellent resistance to water, moisture and environmental contaminants, making it suitable for outdoor and industrial sealing applications.

Is Silicone Foam Flame Retardant?

Most industrial-grade silicone foam materials comply with UL94 flame-retardant requirements and are widely used in electronics, battery and transportation industries.

Can Silicone Foam Reduce Vibration?

Yes. Silicone foam provides excellent shock absorption and vibration damping, helping protect sensitive electronic and mechanical components.

How Fast Can You Provide Samples?

Standard material samples are usually available within 1-3 days.
Custom die-cut samples are typically completed within 3-7 working days depending on complexity.

Why Do Global Manufacturers Choose Silicone Instead Of Ordinary Rubber?

Because silicone offers:

✔ Wider temperature resistance
✔ Better aging resistance
✔ Superior flame retardancy
✔ Longer service life
✔ More stable performance

This often reduces maintenance costs and improves product reliability over time.
