Electronics produce HEAT and must be COOLED

This is a growing problem for:


A new category
of thermal metamaterials to redirect heat within electronics

We deliver a new category of thermal metamaterials. Physically speaking, this results in shrinking or removing heat sinks, decreased weight, volume and material costs. EMI shielding is also being explored.

Being cool by design
has advantages

Energy savings

Testing has shown that increases in cooling performance
of electronics can be made through the use of thermally anisotropic materials. The bottom line: cost savings for the user!





FAQ / Technical Questions

What can I expect from this material?

HyMet is a composite thermal interface material manufacturing technology for applications within computing, telecom, e-mobility and consumer goods. It's unique characteristics allow it to:

  • spread heat like a graphene
  • deformed plastically like a putty
  • wet surfaces like a grease
  • be cut or stamped like a silicone
  • manufactured to specific thicknesses from 0.2 to 1.0mm
  • be applied in sheets over large areas
  • maintain unbeatable performance/price ratios
How does it work?

Our composite thermal interface material has two primary components, a solid phase and a liquid phase. This makes it naturally tacky and workable.

The solid phase redirects heat and conforms to uneven surfaces, the liquid phase helps maintain a highly thermally conductive boundary layer between all contact points. Together they make an extremely versatile and stable material which is also highly thermally anisotropic. HyMet materials easily deform and stick to rough or uneven surfaces, requiring little pressure for up to 70% plastic deformation.

Heat spreading materials are excellent for keeping the exterior of consumer goods cool

Large uniformly thick sheets of HyMet TIMs can replace messy and complicated gap fillers and foams

Heat sink dimensions in 5G technology can be reduced significantly

HyMet TIMs can save size and weigh in many emergent technologies

Our Roadmap?
Is HyMet material a heat spreader or a thermal interface?

Yes. HyMet is a composite material which behaves as both a heat spreader AND a thermal interface material. Its surfaces are wet and its consistency is flexible so that it can be bent around curved or uneven objects. It can be cut like a thermal pad but also molded or layered like a putty, but keep in mind that it will always conduct heat very well along its XY axis, it is a highly anisotropic material in this respect.

Is there only one kind of HYMET material?

No. We have designed a process for manufacturing a new class of composite material. This material is made up of several phases and is processed in order to achieve its special properties. The materials used in each phase of the composite can be replaced or exchanged with other materials that have more desirable properties that suit an application. As a result, HyMet materials can be customized for your applications.

Do I need also need to apply a thermal grease in order to make good contact when using this?

This composite material is "self wetting" and when a light activation pressure is applied, a small amount of the liquid phase is released which creates a good, even contact with the surfaces, eliminating voids and air pockets.

Can I bend HYMET material?

This material can be bent or wrapped around objects and conducts heat extremely well in-plane. Cylindrical batteries can be wrapped easily.

What is the largest area I can cover with this material?

This HyMet material is currently produced in 20X15cm sheets with the end goal of 100X100cm sheets. This format makes it excellent for applications to large areas where foams or gap fillers are typically used.

Does HYMET material "off-gas"?

Offgassing is the result of the materials chosen to manufacture our composite, if non-offgassing materials are required, they can be incorporated.

How well developed is this technology?

Currently our material has reached TRL5 and XY thermal conductivity has been validated to be over 45W/mK in our first composite.

Can I test this material out?

We are conducting proof of concept testing with a variety of potential customers. If interested, please just reach out and tell us about your proposal or the specifications you are trying to reach and are interested testing.
