Our engineering team is an extension of your team, providing expertise in those niche areas possibly not covered by your engineering experience.  We can quickly understand your performance needs and make design suggestions or model as appropriate to offer improvements in design.

Adhesiveless Lamination Technology

Our extensive history and experience has generated unique manufacturing processes that produce robust solutions suitable for use in the most demanding environments. Fralock’s pioneered Adhesiveless Lamination Technology (ALT) eliminates the need for degradable adhesives, and produces bonded polyimide components that are able to withstand extreme thermal, physical, and chemical stresses. Components made with adhesiveless lamination are used in space, medical, industrial, and other industries that require integrity under extreme conditions and/or for extended time.

ALT is highly suitable to multiple applications such as thermal barriers, flex and rigid flex circuits and cables, heaters, gaskets, and more. Fralock is the sole licensee of DuPont Cirlex®, a thick polyimide that can be fabricated into a wide range of shapes and sizes and can be precision machined. Made from 100% DuPont Kapton® adhesiveless polyimide film, Cirlex® delivers performance and value for all your demanding applications.

Fralocks’ polyimide thermofoil heaters are manufactured with our adhesiveless lamination, producing thin, lightweight, flexible and incredibly durable all-polyimide heaters.

Fralock Specialty Laminates

Fralock provides laminated solutions for a range of capabilities used in several different industries.

Depending upon your requirements for chemical resistance, temperature range, and outgassing concerns, we have a solution that is right for you.

Our laminate processes and materials are suitable for applications that require stable adhesion ranging from -269°C degrees to 350°C. Choose from pressure-sensitive tapes, heat-activated adhesives, high-performance adhesiveless all-polyimide lamination solutions that provide durable bonding for extreme environmental conditions.

Our all-polyimide flex circuits are smaller, lighter, and can seamlessly integrate into almost any form you need. Fralock builds flex circuits to your exact specifications with predictable performance and high reliability. Rigid-flex circuits combine a flex circuit with a rigid conductor such as a connector or a circuit board, and can be found in applications ranging from medical infusion pumps to aircraft guidance systems.

Fralock’s flex and rigid-flex solutions include flexible all polyimide heaters, flex cables flex and rigid flex circuits, electronic assemblies, and electrostatic chucks (semiconductor manufacturing).

Our advanced flex circuit technology can help achieve your manufacturing goals when unique components and functions are needed.

Fralock’s Flex Cables

Learn about our Etched Foil Flex Cables

Flexible Etched Foil Cables for Power Distribution – conductive metal tracings are sealed between two layers of polyimide insulation. Only Fralock’s flex cables are made with our 100 percent Adhesiveless Lamination Technology (ALT), which mechanically bonds the layers of foil and polyimide insulation with each other, locking the conductive elements in place and eliminating the use of adhesives. Legacy technology uses PTFE to bond the layers of material together, but the bond is weak, often resulting in poor adhesion that can cause cracking and delamination. This produces fragile cables with poor radiation resistance and less structural integrity.

With our polyimide ATL bonding, delamination and cracking is eliminated, and cables are fully operational in extreme environmental conditions. Fralock can produce high 4,000 to 8,000 dpi registration, and can be produced in lengths up to 50 ft.

Device and equipment manufacturers demand thermal and electrical interface materials that provide high-end performance and consistent long lasting reliability. Our solutions provide excellent electrical insulation for high-voltage applications, as well as thermal barriers/breaks in extreme heat up to +351°C (+664°F).  We provide product realization for seals, gaskets, rings, and thermal spreaders.

Ceramic Solutions

Learn about our Ceramic Solutions.

Fralock provides technical ceramics for a variety of applications. We engineer and manufacture metalized active ceramic heaters as well as structural ceramics.

Using a unique formulation of Aluminum Nitride (AlN) ceramic with co-fired internal Tungsten (W) traces for heating and temperature sensing, we design and manufacture rapid-fire and heaters with exceptional thermal uniformity, watt density, and temperature ramping capabilities. This solution is suitable for applications that require precise, rapid control of heat and cooling.

Our engineered structural ceramics are used in a wide array of  applications to provide chemical stability over a wide temperature range, hardness, electrical insulation, dielectric capabilities, durability, and high strength. We apply high-precision technology (laser machining, drilling, ceramic machining, lapping),  to produce almost any shape and size needed.
