By combining cost effective screen-printing techniques, flexible substrates, and the latest functional inks; Butler Technologies, Inc. produces flexible printed heaters and warming elements for many applications such as:
- Automotive Seat Warming
- Food service
- Healthcare and Medical applications
- Consumer Products
What are Flexible Printed Heaters?
Simply put, Flexible Printed Heaters are warming elements that are screen printed on flexible materials. Through the precise control of design elements and deposition of functional inks, flexible printed heaters can be made to specific operating parameters. To create these unique heater applications; a full range of conductive, resistive, and positive temperature coefficient inks are used in combination with flexible substrates such as polyester (PET), polyimide (PI), polycarbonate (PC), Kapton ® RS Conductive Film, and thermoplastic polyurethanes (TPU).
BTI produces traditional fixed resistance wire heaters , Kapton ® RS film heaters and PTC (Positive Temperature Coefficient) self-regulating heaters. The traditional fixed resistance heaters utilize printed silver or carbon ink coils to produce heat. This type of heater is generally simple to produce and cost-effective but typically requires the use of external diagnostics or controls as they do not self-regulate. Kapton ® RS offers consistent unform heat with temperatures up to 240° C.
Positive Temperature Coefficient (PTC) Heater
A screen-printed PTC heater utilizes a silver BUS system with self-regulating carbon elements. This means that the printed heater is capable of regulating its temperature without any outside controls. When power is applied, the resistance increases and limits the electrical current to the heater causing it to cool. As the heater cools, electrical current will increase again causing it to reach its operating temperature, thus self-regulating. This creates a safe and efficient warming element which eliminates the risk of overheating. Flexible Printed PTC heaters provide more uniform heat with no hot spots, require less power to operate and are safer to use due to their cold-state failure mode.
