What Are Flexible Heaters? Polymide vs. Silicone

Introduction Flexible heaters are thin, lightweight, and customizable heating elements used for precise temperature control in compact or complex spaces. These heaters are designed to convert electrical energy into heat through resistance heating. This process involves electricity flowing through a resistive element embedded within the flexible substrate, which generates heat as it meets resistance. The materials used are highly effective at conducting electricity and distributing heat evenly. Based o......

Choosing the right 3M Adhesives Backing for Flexible Heaters: 9448A vs. 468MP vs. 55236

In the world of modern electronics, whether you're working on medical devices or industrial automation, getting thermal management right is absolutely critical. Flexible heaters, typically made from polyimide or silicone, are fantastic tools that give us the versatility to heat complex surfaces. But here’s the catch: a heater's performance is only as good as its mounting. A weak or improper bond can lead to thermal hotspots, mechanical failure, and a product that dies long before its time. This is whe......

EV Battery Thermal Management with Flexible Heaters: What You Need to Know

Electric vehicles (EVs) depend on lithium-ion batteries that are highly sensitive to temperature changes. In cold environments, battery capacity and charging efficiency drop significantly, reducing range and performance. To address this, EV battery thermal management systems regulate battery temperature to maintain optimal operating conditions. Flexible heaters are a key component of these systems, providing fast and even warming directly to the battery pack to maintain safe, reliable operation and ex......

Choosing Insulating Materials for Flexible Heaters

Introduction When it comes to designing any thermal system, the heating element alone isn’t the whole picture. The performance, safety, and longevity of a flexible heater are then ultimately defined by its insulating materials. These insulating materials are not just a protective covering - they are effectively a part of the construction of a heater and define thermal performance, electrical integrity, and mechanical robustness. For engineers designing embedded systems or any product, selecting the ri......

Choosing the Right Substrate for Flexible Heaters: A Guide to Copper, Stainless Steel, and FeCrAl

Introduction Developing a heating element for a small medical device or a rugged outdoor sensor presents a unique thermal engineering challenge. The solution usually does not lie with the heater, but instead with the substrate. Flexible heaters are an effective modern solution to these complicated thermal challenges. However, the performance of the flexible heater is determined by the substrate material on which it is constructed. Many flexible heaters are constructed on polyimide or silicone, but the......
