Project Description

conductive-Ni-particlesEPRUI supplies highly uniform nickel plated particles which has high conductivity and appropriate elasticity. There is also a strong adhesion between the metal layer and the resin core of EPRUI conductive Ni particles. As a conductive filler, Nickel conductive spacers are used in coatings, adhesives, printing ink, plastics, and rubber to provide electrical conductivity, electromagnetic shielding, and antistatic resistance in electronics, communication devices, and avionics.

1. Monodisperse resin particles as core and metallic nickel as shell

2. Broad size selection: 3.0 µm − 10.0 µm (in 0.1 µm increment)

3.Uniform in size and shape, coefficient of variation (CV) ≤ 3.5%

4. Good dispersivity, no overlaps or aggregates

5. Suitable hardness for high conduction reliability

6. Low resistance, high stability under heat and humidity
