Our PTC heating technology portfolio has evolved over the past 6 years - developed with the goal to provide safe and efficient heating products globally. Compared to traditional carbon fiber or wire options, PTC heating is safer, more reliable, and it can be used in a variety of applications, from healthcare equipment to automobiles.
In this article, we’re exploring how this technology works, and we’re sharing the benefits of using PTC heating technology on flexible substrates.
Traditional heating technology uses elements like coils or carbon fibers to generate heat. With this type of technology, an electrical current flows through the coil, and the electrical energy is converted into heat, which then radiates from the heating element.
For example, if you look inside a toaster and see glowing coils or ribbons, this is exactly what’s happening. While this technology has been used for years, it comes with many challenges, such as overheating, uneven heating, higher energy consumption, and more.
PTC heating, which stands for “positive temperature coefficient,” solves many of these challenges. PTC heating technology uses conductive ink that is printed on flexible materials. As the name suggests, conductive ink is a material that conducts electricity. It essentially allows you to draw or create working circuits on thin materials and textiles, such as polymer-based substrates. The ink is typically infused with graphite, silver, or other conductive materials.
Moreover, PTC heaters are self-regulating and use “positive temperature coefficient” materials, which means that the electrical resistance increases whenever the temperature increases. In other words, this self-regulating material restricts the electrical current when temperatures rise, and it allows more current to pass when temperatures decrease. Because it runs open-loop, there is no need for external diagnostic controls.
PTC heating technology has opened up a new world of opportunities for manufacturers. Since substrates are so thin and flexible, this makes it possible to include heating elements virtually anywhere, without the need for bulky coils.
Here are some of the main benefits of using PTC heating technology on flexible substrates:
