Self-vulcanizing silicone tape PYROSIL used for sealing the PYROJACKET cover and PYROTAPE. It does not have an adhesive layer, but when overlapping itself or on PYROJACKET or PYROTAPE, it vulcanizes in a few seconds. Resistant to radiant heat, moisture, and vibrations. Due to its very good dielectric strength, it is suitable as an electrical insulator. A 50% overlap and a clean, dry surface are recommended during installation. Not recommended for contact with flames and splashes of molten metal. Material: silicone in rust color. Operating temperature: up to +246°C.
