Self-limiting temperature electric heating tape overview
Self-limiting temperature electric heating tape, also known as self-regulating temperature 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 resistance of its PTC heating element has a high positive temperature coefficient and is connected in parallel.
Self-limiting electric heating tape features
Self-limiting electric heating tapes can automatically control the heating temperature and adjust the output power according to the temperature of the heated object; they can be cut to any length or extended within a certain range; they allow multiple crossings and overlaps without the risk of overheating and burning; they are easy to maintain and energy-efficient.
