Saint-Gobain® Norseal® 200A Silicone Sponge Tape

Saint-Gobain® Norseal® 200A Silicone Sponge Tape is a durable, high-performance pressure-sensitive tape designed for sealing, gasketing, and insulating applications in challenging environments. It features a compressible silicone sponge backing paired with an aggressive acrylic adhesive that provides strong initial tack and long-term adhesion to a wide variety of surfaces. Ideal for high-vibration or uneven surfaces, 200A delivers excellent sealing, noise reduction, and cushioning while maintaining performance across a broad temperature range.

Applications include: Military, drones, GPS, walkie talkies, energy storage devices, environmental gasketing, noise reduction, clamping high temp parts, and electrolysis reduction between dissimilar metals.
