Silicone Foam Tube

The silicone foam tube is a closed-cell elastomer material. It is expanded when it is heat-cured to generate many tiny bubbles that are not connected through the passage of the material. Thus creating excellent sealing and insulating resistance to fit a variety of applications.

We offer a wide range of sizes with inner diameter from 2mm up to 60mm and outer diameter from 6mm up to 80mm. We can customize the length and thickness based on your exact requirements. Our silicone foam tube comes with round type, rectangular type, irregular type, etc. that match your specific requirements.
