Is PYROSIL Self-Fusing Silicone Repair Tape safe for continuous use at +246°C and resistant to moisture and vibrations?

Yes. PYROSIL Self-Fusing Silicone Repair Tape is safe for continuous use at up to +246°C and is resistant to moisture and vibrations. Its self-vulcanizing silicone composition bonds to itself and to PYROJACKET/PYROTAPE, creating a seamless, durable seal with excellent resistance to radiant heat, moisture ingress, and mechanical vibration. It also provides high dielectric strength for electrical insulation. Installation on a clean, dry surface with a 50% overlap ensures optimal performance. Note: not intended for direct exposure to open flames or molten metal splashes.

Can PYROSIL Self-Fusing Silicone Repair Tape be used to electrically insulate splices and connectors in high-vibration industrial environments?

Yes. PYROSIL Self-Fusing Silicone Repair Tape is suitable for electrically insulating splices and connectors in high‑vibration industrial environments. Its self‑vulcanizing silicone bonds to itself and to PYROJACKET/PYROTAPE within seconds, creating a seamless, durable layer with outstanding dielectric strength. The material resists radiant heat, moisture and vibrations, and is engineered for continuous service up to +246°C, making it appropriate where both mechanical and electrical protection are required. For best results install on a clean, dry surface with 50% overlap to ensure maximum sealing efficiency and long‑term durability. Note: it is not intended for direct exposure to open flames or molten metal splashes.
