Single-core silicone wire, resistant to high temperatures, very flexible SiFF 1x0.5mm² yellow 45208

High-temperature silicone wire – flexibility and safety

This single-core silicone wire is an ideal solution where resistance to extreme temperatures and high flexibility are required. The HELUTHERM SiFF wire, made of high-quality materials, ensures reliable operation in harsh industrial conditions and beyond. Its construction guarantees safety thanks to its halogen-free composition, minimizing the risk of toxic gas formation in the event of a fire.

Construction and application

The wire is characterized by a cross-section of 0.5 mm² and is designed to operate in a wide temperature range – from -60°C to +180°C (flexible) and permanently up to +180°C. The exceptional flexibility of the wire, resulting from the use of a multi-strand core (class 6), facilitates installation and routing even in tight spaces. The wire finds application in many industries, such as: steel, metallurgical, aviation, shipbuilding, cement and ceramic. It can also be used in power plants.

Key features and benefits

• High temperature resistance: Trouble-free operation in high-temperature environments, increasing the safety and reliability of installations.
• Exceptional flexibility: Facilitates installation and routing of the wire, even in hard-to-reach places.
• Halogen-free: Ensures fire safety by minimizing the emission of toxic gases during combustion – compliant with IEC 60332-1-2 and DIN VDE 0482-754-1/DIN EN 60754-1/IEC 60754-1 standards.
• Wide operating temperature range: Possibility of use in extreme temperature conditions (-60°C to +180°C).
• Chemical resistance: Exhibits resistance to oils, vegetable and animal fats, alcohols, plasticizers and many other chemicals.
• Rated voltage: The wire is designed to operate at 300/500 V.
• Minimum bending radius: Flexible 12.5x wire diameter; when laid permanently 5x wire diameter – ensures long-term mechanical durability.
• Outer diameter: Approximately 2.4 mm – compact dimensions facilitate installation.

This wire is not only an element of electrical installation – it is a guarantee of safety and reliability in demanding working conditions. Its technical parameters and physical properties make it an optimal choice for both professionals and end-users looking for a durable and safe solution.
