Keratherm® Ceramic tape
KERATHERM® are highly flexible products made of thermally conductive and electrically insulating single or multi-component polymers, which are filled with ceramic or thermally conductive materials.
Keratherm® thermal interface materials ensures efficient cooling of the electronic components by connecting the heat source to the heat sink.
A mechanical reinforcement of Keratherm® by means of integrated glass fiber fabric or other materials offers the user a versatile product. Due to its flexibility and very good physical properties, extensive applications in electronics is possible.
Keratherm® is commonly used in conjunction with power electronics inautomotive applications such as batteries, electric powertrains, LED lighting, on-board chargers, sensors and much more.
- Keratherm® thermal conductive foils have a high thermal conductivity and have an electrically insulating effect.
- By using Keratherm® products, assembly problems such as smearing and assembly errors can be avoided.
- Compared to conventional heat conducting materials, Keratherm® products do not dry out in continuous use and therefore retain their good heat conducting properties for years.
- In contrast to discs made of mica, aluminum or polyamides, Keratherm® products can be used without thermal paste.
- Silicone-based Keratherm® facilitates component assembly due to its self-adhesive properties .
