Product

High-performance extruded sponge/foam silicone tubing designed for extreme temperature resistance, superior thermal insulation, and exceptional sealing performance. Featuring a lightweight, closed-cell microcellular structure, our silicone foam tubes deliver low compression set, excellent weatherability, and UL94 V-0 flame retardancy. Custom densities, wall thicknesses, profiles, and colors are available for demanding applications in EV battery systems, industrial HVAC, railway, and electronics sealing.

Our Sponge & Foam Silicone Tubing is engineered using premium high-consistency silicone rubber processed through advanced continuous vulcanization technology. Designed with a flexible, closed-cell porous structure, this tubing offers an ideal balance of soft compressibility and robust mechanical resilience.

Unlike standard solid silicone tubing, silicone foam tubes provide outstanding thermal protection, shock absorption, and noise damping while drastically reducing overall weight. Engineered to perform reliably under harsh environmental conditions, they withstand continuous temperatures ranging from -60°C to +200°C (with high-temp grades reaching up to +250°C). Whether you require strict UL94 V-0 flame-retardant performance, FDA food-grade compliance, or custom co-extruded profiles, we provide tailormade sealing solutions engineered to your exact specifications.

• Extreme Temperature Stability: Operates continuously from -60°C to +200°C (-76°F to +392°F) without cracking, shrinking, or losing elasticity.

• Superior Compression Set Resistance: Rapidly recovers shape after long-term compression, ensuring long-lasting air, dust, and water-tight seals.

• Lightweight & Closed-Cell Structure: Prevents moisture, fluid, and gas absorption while significantly reducing component weight compared to solid rubber.

• Flame Retardant & Safety Compliant: Available with UL94 V-0 certification, halogen-free, generating low smoke and non-toxic fumes during combustion.

• Excellent Weather & Aging Resistance: Highly resistant to UV radiation, ozone, extreme weather, and harsh chemical environments for outdoor durability.

• High Thermal & Acoustic Insulation: Ideal for thermal management and noise dampening in compact, enclosed housings.

• Fully Customizable: Custom inner/outer diameters, densities (0.25–0.85 g/cm³), colors, and complex co-extruded profiles.
