Self-Regulating Heat Tracing Technology
Raychem self-regulating heating cables can be used to protect pipes from freezing, maintain process temperatures for liquids, heat tanks, melt snow on roofs and surfaces, provide instant hot water at the tap and even to heat floors.
As the inventor of self-regulating heat-tracing technology, with over 1.8 billion feet (550,000 km) of heating cable sold in over 100 countries, Raychem is the most recognized brand and global standard in heat tracing.
How Self-Regulating Heating Cables Work
Raychem self-regulating heat trace cables consist of two parallel conductors embedded in a heating core made of conductive polymer. The core is radiation-cross-linked to ensure long-term reliability.
Heat is generated as electric current passes through the conductive polymer core between the cable’s conductors. As the ambient temperature drops, the number of electrical paths through the core increases and more heat is produced. Conversely, as the temperature rises, the core has fewer electrical paths and less heat is produced.
Raychem self-regulating cable technology is available in a range of products suitable for use in the home, in construction for larger buildings, and for industrial-based applications.

50 Years of Self Regulating Technology
In 1972, the heat tracing division of the Raychem Corporation (now a part of Chemelex) patented and produced the world’s first commercially successful electric self-regulating heat tracing cable. Since then, the company has sold and installed over 1.8 billion feet (550,000 km) of heating cable in over 100 countries.
