The conductive filler socketless fitting can be divided into

Metals, carbon, metal oxides, inorganic salts, a conductive polymer, the composite conductive filler and as
The surfactants used as an antistatic agent. The first conductive filler metal is silver, the advantage of power
Resistance is low, the rate of oxidation is slow, and the conductive oxide, the use of silver as a conductive filler mainly two
Problems: First, the price is expensive; is Transfer evils. Silver migration can be controlled by the water in the coating
Points to resolve. Copper is a metal conductive filler, but not having electrical conductivity due to its oxide, in the
Must prevent copper oxidation, and must be processed before use, that is, to take effective oxidation technology
Surgery. In addition to the development of nickel powder, metal alloy powder conductive filler.

Carbon-based conductive filler comprises carbon black and graphite, metal oxide based conductive filler is the resistivity in the range of 0.01 --- 1.
Oil cm between the metal oxide, a conductive polymer can also be used as the filler added to the insulating film-forming material
Made to add conductive coating. In order to reduce costs and improve the conductive properties, the composite conductive filler. As
Mica, glass beads or other inexpensive metal powder outer cladding on the use as a conductive filler such as silver, copper,
The composite powder and composite fibers.
