Self-regulating heaters with PTC ink

PET foil heaters printed with PTC self-regulating ink

Alper promotes PTC (Positive Temperature Coefficient) technology. A special carbon ink with PTC effect is printed on a flexible and thin PET substrate by screen-printing. The "self-limiting" heater reaches the temperature defined by the PTC ink without exceeding it.

How does an Alper PTC heater work?

When the temperature of the system increases, the PTC heater increases its resistivity with the consequent decrease in its power.

PTC ink printed Alper heaters feature intelligent technology.

Alper heating elements printed with PTC ink are self-limiting, as the temperature of the system increases, the PTC heater increases its resistivity with the consequent decrease in its power. This peculiarity, which distinguishes these Alper flexible heaters, makes them suitable even for the most particular and delicate applications, such as those that come into contact with skin and textiles. The PTC ink heater does not require any accessory temperature limiters.
In this way, the heater is thin as a foil and production costs are reduced in order to take advantage of more convenient prices.

On request the product can be adhesive, even in part, and can be completed with any type of cable and connector.
The continuous search for new materials has allowed Alper to make its PTC heaters extremely flexible and performing with long life.

Our production processes guarantee high quality standards combined with a high production capacity. Additive production processes, produce harmless waste to the environment and humans.
