Etched Foil Mica Heaters

Durex Industries’ mica heaters are engineered using etched foil heating elements laminated between two high-temperature mica layers. This construction delivers rapid heat-up times and excellent thermal transfer, making them ideal for applications requiring consistent, high-temperature performance in a compact, lightweight form factor.

To ensure structural integrity and optimal performance, clamped mica heaters must be securely mounted between rigid plates or heated surfaces to prevent delamination.
 

Why Choose Electric Mica Heaters?

Electric mica heaters offer a conductive heating solution designed for high-temperature applications that demand uniform heat distribution. Unlike traditional high-temperature heaters with limited element coverage, Durex mica heaters achieve over 50% element coverage, enabling efficient heat dispersion—even across complex geometries.
