Products and Technology

High heat conductivity resin

Binding small amount, low-cost filler material together effectively allows formation of thermal conductive channels with 10 to 30 times thermal conductivity as much as ordinary resins.
These materials can also be used as products to help thermal discharge, and their high degree of fluidity means they can be formed into complex shapes.

Characteristics

  • It has 10-30 times thermal conductivity as much as the general resin.
  • It is usable as substitute from die-casting and ceramic for heat release. In addition, cost down is possible.
