Flexible Foil Heaters Ireland, Heat Precisely Where Standard Heaters Cannot Reach

When your component has a curved surface, a tight space, or must be heated uniformly across a flat area without rigid mounting points, flexible heaters are the solution. Also known as foil heaters or silicone rubber heaters, they conform to the shape of your component and deliver precisely controlled heat where it is needed nothing more, nothing less.

Frequently Asked Questions — Flexible Heaters Ireland

What is the difference between a silicone rubber heater and a Kapton heater?

Silicone rubber heaters are thicker, more durable, and better for industrial applications where the heater may be handled or flexed repeatedly. Kapton (polyimide) heaters are ultra-thin (as thin as 0.2mm), extremely flexible, and ideal for tight spaces or precise applications where minimal heater mass is critical, such as aerospace and medical instruments.

Can flexible heaters be made to a custom size or shape?

Yes. Custom flexible heaters are available in any shape round, rectangular, irregular, or with cutouts/holes for mounting fasteners or sensors.
