EMI 1387 Closed-Cell Silicone Foam Tape
EMI 1387 Closed Cell Soft Silicone Foam Tape is a lightweight, liquid-cast silicone foam engineered for versatile performance in sealing, cushioning, and vibration isolation. With its soft, compressible structure and excellent rebound, EMI 1387 excels in both protective and environmental sealing roles. It offers superior thermal stability, aging resistance, and food-contact compliance, making it an ideal material for use in electronics, appliances, transportation, and industrial enclosures. The foam meets UL 94 V-0 and HF-1 flame resistance standards for added safety in sensitive applications.
Applications include: High temperature or indirect food contact applications ranging from transportation, electronics, appliances, to enclosure sealing.
- Ideal for low-compression sealing, shock absorption, and food-grade thermal protection applications
- Available from thickness ranging from 0.063 in to 0.5 in
