What is a Flexible Heater? The Basics Explained

Flexible heaters are thin, lightweight heating elements that can conform to curved or irregular surfaces.

Unlike traditional rigid heaters, they're built on flexible substrates like polyimide (PI) or silicone rubber with etched or printed resistive heating traces.

They're perfect for applications where space is limited or the heating surface isn't flat - think 3D printer beds, medical devices, aerospace components, and battery thermal management.

Typical thickness ranges from 0.1mm to 3mm depending on the construction.
