Saint-Gobain® Norseal® 515GF Silicone Foam Tape
Saint-Gobain® Norseal® 515GF Silicone Foam Tape is a flame-retardant, lightweight tape made from F-15 modified silicone foam and paired with a film-supported acrylic adhesive. Designed for use in aerospace, electronics, and industrial sealing applications, 515GF offers a unique balance of compressibility, weather resistance, and dimensional stability. Its closed-cell structure resists water, air, and dust ingress, while maintaining excellent thermal and environmental performance across a broad temperature range.
Applications include: Military, drones, GPS, walkie talkies, environmental gasketing.
- Durable performance in harsh environments (UV, ozone, moisture)
- Ideal for gasketing, thermal insulation, and sealing in compact or weight-sensitive assemblies
- Available from thickness ranging from 0.063 in to 0.25 in
