金属めっき系高機能フィラー ミクロパール™

High-Performance Metal Plated Filler Micropearl™

High-performance functional filler that combines flexibility and conductivity without causing damage

A high-performance metal-plated filler, developed using our proprietary particle manufacturing technology, delivers excellent particle size uniformity and dispersibility. It is flexible and ensures stable conductivity across a wide contact area while minimizing damage to contact surfaces. It applies to a broad range of fields, including semiconductors, electronic devices, and lithium-ion batteries (LIBs).

  • Evaluation reference value based on resin core of 10 μm
  • The above is not the standard value. This varies depending on the particle size and metal film thickness.

Comparison in specific gravity with metal powders

As Micropearl™ boasts lower specific gravity compared to metal powders, it can reduce sedimentation in composite material and reduce the material weight.
