High Temperature, Flexible & Rigid-Flex Heaters

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.
