High Temperature, Flexible & Rigid-Flex Heaters

All Polyimide Adhesiveless Heaters- Flexible & Rigid-Flex

Fralock’s adhesiveless heater technologies are unsurpassed in the industry. We offer a proven success in a wide range of critical applications. Our heaters deliver reliable, precise, heat exactly where you need it, when you need it, utilizing our unique thin, flexible adhesiveless proprietary design.

Fralock’s ability to make multi-layer, all polyimide, and heaters is what makes us unique. This technology uses no adhesives of any type, only true adhesiveless polyimide films. Fralock’s proprietary technology to create a multi-layer, all polyimide heaters that have no adhesive of any type are unmatched in the industry.

Other competing constructions use adhesives that form weak links and have other physical properties that interfere with the heaters construction and reliability.  By eliminating the structural weak links, Fralock heaters surpass historical limitations of traditional heater construction.

Fralock custom manufacturing can design and fabricate your heaters to a multitude of shapes, sizes and wattage. Polyimide heaters are thin and light weight with excellent dielectric strength. Polyimide heaters are preferred for applications where space, weight, and low out gassing limitations exist.
