EMI 1384 Closed-Cell Silicone Foam Tape

EMI 1384 Closed Cell Silicone Foam Tape is an extra-firm, liquid-cast silicone foam designed for heavy-duty sealing, gasketing, and vibration isolation in extreme environments. Engineered for superior mechanical performance and environmental durability, EMI 1384 withstands high compression forces, resists weathering and aging, and retains flexibility even at sub-zero temperatures. Comparable to HT-840, it meets UL 94 V-0 and HF-1 flame resistance standards and is FDA compliant for repeated food contact, making it ideal for the most demanding applications in transportation, electronics, and industrial systems.

Applications include: High temperature or indirect food contact applications ranging from transportation, electronics, appliances, to enclosure sealing.

 
 
  • Ideal for high-force sealing, enclosure gasketing, and long-term protection in harsh or thermally extreme environments
  • Available from thickness ranging from 0.063 in to 0.5 in
