Saint-Gobain® Norseal® 512GF Silicone Foam Tape
Saint-Gobain® Norseal® 512GF Silicone Foam Tape is a lightweight, foam tape designed for demanding gasketing and environmental sealing applications. Made from flame-retardant F-12 silicone foam and paired with a film-supported acrylic adhesive, 512GF offers reliable compression, excellent thermal stability, and strong resistance to UV, moisture, and ozone. Its soft, conformable structure makes it ideal for sealing enclosures and protecting sensitive electronics in harsh indoor or outdoor environments.
Applications include: Military, drones, GPS, walkie talkies, environmental gasketing.
- Excellent UV, ozone, and weather resistance
- Ideal for low-compression-force gasketing, sealing, and vibration isolation applications
- Available from thickness ranging from 0.063 in to 0.25 in
