Black Silicone Sponge: Durable and Versatile Sealing Solution
Yunli Technology presents its high-performance black silicone sponge, a robust and adaptable material engineered to deliver exceptional sealing, cushioning, and insulation across a wide range of industrial applications. Manufactured with precision and consistency, this closed-cell foam material combines the inherent advantages of silicone-excellent temperature resistance, weather ability, and flexibility-with a uniform sponge structure ideal for demanding environments. The black silicone sponge is particularly valued for its durability, UV stability, and reliable performance in both indoor and outdoor settings.
Our advanced manufacturing process ensures optimal cell structure and consistent density, allowing the material to perform effectively in temperatures ranging from -60°C to 200°C. The black color not only provides a professional appearance but also enhances weatherability and UV resistance, making it suitable for long-term outdoor use. With good compression set resistance and recovery properties, this sponge material maintains its sealing integrity over time, even under repeated compression cycles.
Key Features:
Excellent thermal stability and flame retardancy (UL 94 V-0 available)
Superior resistance to ozone, UV, and weathering
Good acoustic and thermal insulation properties
Customizable density, thickness, and compression hardness
Closed-cell structure prevents moisture absorption
Applications:
Automotive: Sealing for doors, windows, and electronic compartments
Electronics: Gasketing, EMI shielding, and vibration damping
Construction: Weather seals and expansion joint fillers
Industrial: Machinery isolation, pipe insulation, and protective padding
HVAC: Air duct sealing and thermal insulation
Available in sheets, rolls, or custom die-cut forms, Yunli's black silicone sponge can be tailored to meet specific application requirements, including custom dimensions, adhesion options, and specialized formulations. With ISO 9001 certification and a commitment to quality, we ensure every batch meets rigorous performance standards. Contact our team to discuss how this reliable material can enhance your products.

Feature |
Rugged - When silicone is required, silicone sponge parts offer better toughness as compared to silicone foam products. Wide operating temperature - Silicone sponge has a temperature range of -58°F to 500°F (-50°C to 260°C). Water sealing - the closed cell structure allows for good water sealing with relatively low compressive forces.
Compression set resistance - Silicone offers excellent compression set resistance (ability to rebound to original thickness), especially at higher temperatures, compared to most rubber material. Low compression set silicone sponges are available for even better performance than general purpose grades.
UV and ozone resistance - Silicone products have excellent UV and ozone resistance due in part to their inorganic backbone. This provides long term performance. |

FAQ: Black Silicone Sponge
Q1: How does the black silicone sponge perform in constant outdoor exposure compared to other materials?
A: Our black silicone sponge maintains excellent performance under prolonged outdoor exposure, with UV resistance exceeding 5,000 hours in accelerated weathering tests. It outperforms EPDM and neoprene in ozone resistance (ASTM D1149) and retains over 90% of its original flexibility after extended UV exposure, making it ideal for automotive, marine, and construction applications.
Q2: Can the material be customized for specific compression requirements in vibration damping applications?
A: Yes, we offer customized compression hardness ranging from soft (10-15% deflection under 5 psi) to firm (30-35% deflection under 5 psi). Our engineering team can tailor the cell structure and density to achieve specific vibration damping coefficients, with typical transmission loss of 15-25 dB across frequencies of 100-1000 Hz.
Q3: What certifications does your black silicone sponge hold for industrial applications?
A: Our material meets UL 94 V-0 flame retardancy, RoHS, REACH, and ASTM E84 Class A standards. We provide full certification documentation, including material safety data sheets and performance test reports, ensuring compliance with international industrial and environmental regulations.
Q4: How does the closed-cell structure enhance performance in liquid environments?
A: The closed-cell structure provides water absorption rates of less than 1.5% by volume (ASTM D1056), making it suitable for liquid immersion applications. It maintains its sealing integrity even when exposed to oils, chemicals, and moisture, with minimal swelling or degradation over time.
Q5: What technical support do you offer for large-scale projects?
A: We provide comprehensive project support including material selection guidance, prototyping, performance testing, and on-site installation consultation. For large orders, we assign dedicated technical managers to ensure seamless integration and optimal performance throughout your project lifecycle.
