Thermal Putty pads

High Compressibility and Thermal Conductivity


Thermal putty pads

Thermally Conductive Putty Pads provide high thermal performance and solid thermal reliability. The material’s putty-like consistency enables excellent gap-filling capability for applications with large dimensional variances.

Special surface reinforcement enables easier handling for operators, with no pull-out during high-volume assembly. The product is naturally tacky and requires no additional adhesive to mate to the heat source and heat sink. Putty pads combine ultra soft - high compressibility with a low surface impedance that is complemented by natural tackiness and ease of application.

Typical applications for putty pads can be found in EV battery & charging stations, automotive electronics, power devices & modules, telecommunications & network servers.

Thermal putty pads are available in thicknesses ranging from 0.5mm to 5.0mm.

What are the benefits of Thermal putty pads?

The material’s putty like design makes it ultra soft and compressible and enables excellent gap filling capability for applications with large dimensional variances. Special surface reinforcement enables easier handling for operators during high volume assembly.

The hardness is completely different compared to gap pads. Putties are soft and require little to no pressure, something that makes them good replacements for thermal gels. They are non electrically conductive and come in large form factors they work great if properly handled.

Additionally, they are naturally tacky and require no additional adhesive to mate the heat source and heat sink.
