Flex Heaters

Fralock’s heater technologies are unsurpassed in the industry, with solutions for a wide range of critical applications. We offer capabilities that satisfy requirements spanning many applications.

All Polyimide Adhesiveless Heaters – Flexible, Lightweight, Rugged
Our polyimide flexible heaters with etched foil circuits deliver reliable and precise heat exactly where you need it, when you need it, utilizing our unique thin, flexible adhesiveless proprietary design.

Fralock has developed a unique capability to produce multi-layer, all polyimide heaters with technology that uses no adhesives of any type, called Adhesiveless Lamination Technology (ALT). Other competing constructions use adhesives that form weak links with physical properties that interfere with the heaters’ conformation and reliability. By eliminating the structural weak links, Fralock heaters surpass historical limitations of traditional heater construction. We can help with design and fabricate of your heaters to fit a multitude of shapes, sizes, and wattages. We offer single zone, multi-zone, as well as multi-layer heaters. We can also integrate thermal management onto the heater (thermistor, RTD, thermocouple) allowing more precise thermal control, and we can add connectors to provide a full turnkey thermal solution. Flexible polyimide heaters made with ALT are included in our ALT Dura™ product group.

Structurally similar to our flexible flat cables and flexible circuits, thermofoil heaters incorporate etched metal tracings between two sheets or strips of polyimide material, and are ideal for applications that require complex shapes and contours, as well as those with tight space and weight constraints.

ALT Dura™ polyimide heaters are thin and lightweight with excellent dielectric strength, multi-element redundancy, embedded sensing and an average 20% mass savings over classic foil heater construction utilizing adhesives. Polyimide heaters are preferred for applications with limitations on space, weight, and outgassing.
