Saint-Gobain® Norseal® F-20 Silicone Foam Tape

Saint-Gobain® Norseal® F-20 Silicone Foam Tape is a high-performance, flame-retardant foam tape designed for critical sealing and insulation applications in harsh environments. Constructed from a medium soft closed-cell silicone foam, F-20 provides superior durability, dimensional stability, and resistance to weathering, temperature extremes, and chemical exposure. Its medium density and robust adhesive system make it ideal for sealing enclosures, dampening vibration, and providing thermal protection in aerospace, electronics, and industrial applications.

Applications include: Outdoor lighting, aerospace, medical equipment, rail car.
