Overview of Self-limiting Electric Heat Trace

Self-limiting temperature electric heating tape, also known as self-regulating electric heating tape, is a new generation of strip-shaped constant temperature electric heating product. It is composed of high polymer conductive carbon particles, two parallel busbars, and an insulating layer. The PTC heating element has a high positive temperature coefficient of resistance and is connected in parallel.

Self-limiting temperature electric heating tape features

Self-limiting heating tape can automatically control the heating temperature and adjust the output power according to the temperature of the heated object; it can be cut to any length or extended within a certain range; allows multiple overlaps without the risk of overheating and burning; easy to maintain and energy-saving.
