What are PTC heating films?

PTC heating films are flat, flexible heating elements in which a special heating layer made of PTC material is embedded between carrier and cover layers.

They only heat up to the extent necessary for their respective application and require no additional sensors or control units. This makes them particularly safe, economical, and low-maintenance.

PTC heating films are used wherever uniform, even heat is required, e.g. in batteries, technical devices, medical applications or vehicle components.

PTC heating foils: Special paste ensures integrated heat regulation

PTC films become by means of PTC paste (Positive Temperature Coefficient) and conductive silver are produced using a screen printing process. The PTC paste is a special conductive organic substance containing components with a positive temperature coefficient of electrical resistance.

This property enables the production of heating elements that can regulate their own temperature without external control elements. And all this with extremely low profiles starting at 200 µm.

Do you want to reliably control the temperature of your products without additional regulation effort? Then rely on self-regulating PTC heating films from Embro.

How does the temperature control work?

• When electricity flows through the PTC paste, it heats up.
• As the temperature increases, the electrical resistance of the paste also increases.
• This increased resistance limits the current flow, thereby reducing further heating.
• This effect leads to a self-regulating heating effect, in which the temperature is kept at a stable level.

The advantages of PTC heating elements at a glance:

Self-regulating and safe warmth: The integrated PTC technology enables automatic adjustment of the heating power, thus preventing overheating and ensuring safe operation. No external control is required.

Energy efficiency and cost savings: Intelligent heat distribution minimizes energy consumption, reduces operating costs and protects the environment.

Space-saving integration and shape flexibility: The low profile (from 200µ) and low weight allow for space-saving integration, while the flexible shape allows adaptation to different geometries.

Fast response times and flexibility: Short heating times allow for immediate use, and the flexible design allows for use in almost any product and application.

Maintenance-free and resistant to malfunctions: Since there is no wear and tear, no regular maintenance is required. Furthermore, partial damage or breaks in the heating film do not significantly affect the heating performance, which increases reliability. Continued operation is therefore possible even in the event of damage.

EMC compatibility and uniform heat distribution: Low electromagnetic emissions allow for use in sensitive electronics environments, while homogeneous heat dissipation ensures uniform temperature control.

Precise temperature control: PTC technology enables very precise control of the desired temperature.

Application example: PTC heating films for optimized battery performance

PTC heating films can be integrated into numerous applications. These heating elements play a crucial role in, among other things, the following: Optimizing battery performance and lifespan, especially from Lithium Ion BatteriesTheir ability to self-regulate heat dissipation enables efficient temperature management, which is advantageous in the following areas:

Preheating batteries:
At low temperatures, PTC heating films ensure rapid and even preheating to guarantee battery performance.

Temperature management:
They contribute to a uniform temperature distribution within the battery pack, thereby avoiding hotspots and extending the lifespan of the cells.

Frost protection:
In extremely low temperatures, PTC heating films protect batteries from damage by keeping them at a safe temperature.

The self-regulating properties of PTC heating films ensure safe operation and minimize the risk of overheating, which is particularly important in applications such as electric vehicles.
