Is PYROSIL self-vulcanizing silicone tape suitable for use as an electrical insulator at high temperatures?

Yes. PYROSIL self-vulcanizing silicone tape is suitable as an electrical insulator at high temperatures. It has very good dielectric strength, resists radiant heat, moisture and vibrations, and is rated for continuous operation up to +246Â°C. For reliable insulation, ensure a clean, dry surface and overlap the tape by about 50% so it vulcanizes properly; it vulcanizes quickly when overlapped or applied to PYROJACKET/PYROTAPE. Note: do not use it in direct contact with open flames or molten metal splashes.

Can PYROSIL self-vulcanizing silicone tape be used on damp or dirty surfaces without affecting vulcanization?

No - PYROSIL self-vulcanizing silicone tape should not be applied on damp or dirty surfaces if you want reliable vulcanization. Although the tape vulcanizes rapidly when overlapped or applied to PYROJACKET/PYROTAPE and is resistant to moisture once cured, the manufacturer recommends a clean, dry surface and a 50% overlap for proper bonding and performance. Moisture, dirt or contamination can impair the vulcanization process and compromise sealing, insulation and durability.

Can PYROSIL self-vulcanizing silicone tape withstand continuous exposure to radiant heat up to +246Â°C without degradation?

Yes. PYROSIL self-vulcanizing silicone tape is rated for an operating temperature up to +246Â°C and is described as resistant to radiant heat, moisture, and vibrations. Under continuous exposure to radiant heat up to +246Â°C it should withstand the conditions without degradation, provided it is installed correctly (50% overlap, clean dry surface). Caveats: it is not recommended for direct contact with open flames or splashes of molten metal, so exposure to such higher-intensity heat sources may cause degradation despite the specified operating temperature.
