What's PTC heat film?

PTC is Positive temperature coefficient of resistance.


A positive temperature coefficient (PTC) refers to materials that experience an increase in electrical resistance when their temperature is raised. Materials which have useful engineering applications usually show a relatively rapid increase with temperature, i.e. a higher coefficient. The higher the coefficient, the greater an increase in electrical resistance for a given temperature increase. A PTC material can be designed to reach a maximum temperature for a given input voltage, since at some point any further increase in temperature would be met with greater electrical resistance. Unlike linear resistance heating or NTC materials, PTC materials are inherently self-limiting.


Positive Temperature Coefficient (PTC) technology is the new cutting edge technology that has changed the heating industry. It is rapidly heating, with a heating system that is self refulating and the heat is uniform across the whole surface.
This new way of heating is extremely durable and uses far less power than traditional technologies.Our UL passed PVC pets heating mat with the PTC technology is water and corrosion resistant leading to longer service life.
No thermostat control is necessary as the technical design of the is made to attain a maximum of 45°C whether it is covered or not.
