Saint-Gobain® Norseal® 512AF Silicone Foam Tape
Saint-Gobain® Norseal® 512AF Silicone Foam Tape is a lightweight, flame-resistant foam tape designed for superior sealing, cushioning, and environmental protection in high-performance applications. Constructed with F-12 modified cell structure silicone foam and a film-supported acrylic adhesive, 512AF offers excellent compression recovery, long-term durability, and reliable adhesion. Its l design helps block moisture, air, and particulates, making it ideal for use in enclosures, electronics, aerospace, and transportation environments requiring dependable flame and weather resistance.
Applications include: Military, drones, GPS, walkie talkies, environmental gasketing, noise reduction, clamping high temp parts, and electrolysis reduction between dissimilar metals.
- Moisture-, UV-, and weather-resistant
- Ideal for enclosure gasketing, environmental seals, and thermal insulation in sensitive electronic and aerospace assemblies
- Available from thickness ranging from 0.063 in to 0.25 in
