EMI 1380 Closed-Cell Silicone Foam Tape
EMI 1380 Closed Cell Silicone Foam Tape is a medium-firm, liquid-cast silicone foam engineered for rugged sealing, cushioning, and vibration isolation in demanding environments. With a balanced combination of durability and compressibility, EMI 1380 is well-suited for high-temperature and food-grade applications. Comparable to HT-800, it meets UL 94 V-0 flame resistance standards and is FDA compliant for repeated food contact, making it an excellent solution for transportation, electronics, appliances, and enclosure gasketing tasks.
Applications include: High temperature or indirect food contact applications ranging from transportation, electronics, appliances, to enclosure sealing.
- Ideal for high-temp gasketing, shock absorption, and environmental sealing in food-safe and industrial applications
- Available from thickness ranging from 0.031 in to 0.5 in
