| Description | Silicone foam tubing, also known as silicone sponge tubing or silicone foam rubber tubing, is a specialized type of flexible, compressible tubing made from silicone rubber foam. Its distinctive characteristic lies in its closed-cell structure, formed through a heat-curing process that generates countless minute, isolated air pockets within the material. The closed-cell configuration effectively seals out external elements, making it exceptionally resistant to moisture, air, and contaminants. Superior thermal and acoustic insulation. This combination of sealing and insulating capabilities, coupled with the material's inherent flexibility, durability, and resistance to a wide range of chemicals and temperatures, positions silicone foam tubes as a preferred choice across numerous industries. Closed-cell silicone foam tube is ideal for applications requiring watertight seals. Such as weatherstripping, seals, and insulation. |
