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.
