Norseal F-12 and F-20 silicone foam rubber provide excellent flame retardance (UL 94 V-0) with low toxicity and smoke generation in a conformable expanded cellular material.
Norseal F-12 has a modified cell structure and is produced in a low density for light gasketing and insulation applications.
Norseal F-20 has a finer cell structure (closed cell) and produced in a medium density for Mass Transit and Transportation applications.
Available thicknesses range from 1/32” (0.8mm) to 1” (25.4mm). The standard color is gray for both F-12 and F-20, but other options like white and black are available, with minimum quantity requirements.
