Closed-Cell Silicone Sponge Foam Tubes – Reliable Sealing & Insulation

Closed-cell silicone sponge foam tubes are a type of closed-cell elastomeric material. It is expanded when it is heat-cured to generate many tiny bubbles that are not connected through the passage of the material. The tubes exhibit good high-temperature resistance, low-temperature resistance, oxidation resistance, and corrosion resistance, making them suitable for various applications like sealing, sound insulation, and insulation. With FDA certification, they are non-toxic and food-safe. Their high tear strength, wide operating temperature range, excellent flexibility, compression resilience, and resistance to UV, ozone, and other chemicals make them a versatile, durable, and reliable solution for sealing and insulation.
