Superior Material Properties and Performance Advantages

The unique closed-cell sponge structure of our tubing delivers benefits that solid silicone cannot match, making it ideal for gasketing, sealing, and damping.

• Exceptional Compressibility and Recovery:

• Our silicone sponge tube can be compressed up to 50% of its original thickness, exerting low sealing force while providing excellent recovery. This property ensures a reliable seal on uneven surfaces and against fragile components without causing damage or distortion.

• Wide Temperature Resilience:

• Designed for extreme conditions, our tubing maintains flexibility and performance in continuous operating temperatures from -70°C to 260°C. It remains pliable at cryogenic temperatures and will not melt or support combustion at high temperatures, ensuring reliability in thermal cycling environments.

• Closed-Cell Construction:

• The uniform closed-cell structure provides inherent low water absorption and excellent resistance to moisture intrusion, making it an effective barrier against humidity, dust, and liquids for long-term sealing applications.

• Superior Environmental Resistance:

•  Our tubing exhibits outstanding resistance to ozone, UV radiation, and weathering, ensuring long-term performance and integrity in both indoor and outdoor applications without cracking or degrading.

Comprehensive Applications Across Demanding Industries

The versatile properties of Shenzhen Forbest’s silicone sponge tubing make it a critical component in numerous high-performance sectors:

• Aerospace and Aviation:

• Used as thermal and environmental seals in aircraft doors, access panels, and insulation jackets, where wide temperature fluctuations and pressure changes are common.

• Automotive and Transportation:

• Ideal for gasketing in engine compartments, sealing electronic control units (ECUs), and providing vibration damping for sensors and components exposed to heat and fluids.

• Electronics and Electrical:

• Serves as protective sleeving for wires and cables, providing insulation and strain relief, especially in applications requiring flame retardancy per UL 94 V-0 standards.

• Food and Beverage Processing: Our FDA-compliant and NSF 51 certified

•  grades are perfect for sanitary gaskets, seals in processing equipment, and insulation for beverage dispensing lines, ensuring safety and hygiene.

• Industrial Machinery:

• Used as door and panel gaskets on ovens, furnaces, and electrical enclosures, providing an effective thermal and environmental seal.

We can manufacture tubing in virtually any combination of inner diameter (ID) and outer diameter (OD), with a maximum OD exceeding 2.5 inches, providing unparalleled design flexibility.

• Specialty Formulations: Our product line includes tubing engineered for specific regulatory and performance needs:

• • Flame Retardant Grades: Compliant with UL 94 V-0 and UL HB for use in safety-critical electrical and aerospace applications.

  • Food & Medical Grades: Compliant with FDA CFR 21.177.2600 and other relevant standards for use in food processing and medical equipment.

  • Low-Smoke, Low-Toxicity Formulations: For applications where passenger safety is paramount, such as mass transit and aviation.

Why Choose Silicone Sponge Tubing Over Solid Silicone or Other Materials?

The decision to use silicone sponge is driven by its unique performance characteristics:

• Lower Sealing Force: Requires less compression force than solid rubber to achieve an effective seal, reducing the structural load on assemblies and fasteners.

• Superior Conformability: Easily conforms to irregular and rough surfaces, filling gaps more effectively than solid materials.

• Excellent Thermal and Acoustic Insulation: The trapped air within the closed-cell structure provides superior insulation properties compared to solid elastomers.

• Lightweight: The sponge structure results in a lighter weight material, which is critical in aerospace and automotive weight-saving initiatives.

• Enhanced Vibration Damping: The compressible nature of the sponge absorbs shock and dampens vibration more effectively than solid rubber.
