How it works

The two electric cables are surrounded by a polymer (insulating plastic) containing graphite particles.

1. It is cold: the polymer contracts. The graphite particles come into contact with each other. The heating tape becomes warm.
2. It is warm: The polymer expands. There is no longer any contact between the graphite particles. The heating tape does not heat up.
