Bisco®
Type
1) BISCO Cellular Silicones are ideal for use as gaskets
and seals, cushions, and thermal and acoustic insulation in demanding
conditions. Both open- and closed-cell offerings withstand temperatures
from -67°F up to 400°F (-55°C to 204°C). All of these
products possess unsurpassed compression-set resistance. They pass
stringent smoke and toxicity regulations and carry the most stringent
UL flame ratings available, 94V-0 and 94HF-1.
