Meeting Today’s Data Center Challenges 

The rapid expansion of cloud computing, AI/ML, and IoT is driving demand for higher-density, higher-speed servers. These systems generate heat, vibration, and acoustic noise while requiring stringent safety and reliability standards. 

PORON® 40V0 polyurethane foam is engineered to meet these challenges. The material combines a UL 94 V-0 flame rating with softness, high conformability, and acoustic performance—helping protect sensitive electronics while reducing noise and cost. 

Why PORON® 40V0 Foam for Data Centers? 

• UL 94 V-0 Certified: Meets stringent flammability standards to enhance system safety. 

• Soft and Conformable: Ideal for gap-filling in densely packed server components. 

• Acoustic Performance: Reduces fan-generated noise and vibration that can interfere with data accuracy. 

• Halogen-Free¹: Produced with non-halogenated flame-retardant materials for compliance with environmental and safety regulations. 

• Siloxane-Free²: Mitigates risk of contamination in sensitive electronic environments. 

• Cost-Effective Alternative to Silicone: Provides required flame rating at a lower cost in cases where extreme temperature and water sealing are not needed. 

• Proven Long-Term Reliability: Engineered to maintain sealing and cushioning performance throughout the service life of data center equipment. 

¹ The International Electrotechnical Commission (IEC) defines “halogen-free” materials as those containing less than 900 ppm of chlorine or bromine, and less than 1500 ppm of total halogens, as outlined in standard IEC 61249-2-21. 
² D3–D10 free per ASTM F2466-10 (non-detected limit = 5 ppm). 

Data Center Applications 

• Gap-Filling and Cushioning → Protects boards and modules with soft, compressible material. 

• Fan Seals and Acoustics → Reduces vibration and absorbs low-frequency fan noise to improve system accuracy.

Performance Advantages in Data Centers 

• High Compressibility 
  Low-density formulation compresses easily, delivering effective gap-filling in densely packed server assemblies. 

• Superior Stress Relaxation 
  Maintains pushback force under constant compression over time, allowing seals to maintain performance over time. 

• Sound Absorption 
  Absorbs acoustic energy generated by high-speed cooling fans, reducing interference with data reading/writing and helping control system noise.
