Description

Magnetite for Toner

Toner is powdery material used for copy machine, beam printer and fax machine and it is exhausted material to be printed and adhered to paper. Magnetite for toner is one of the core ingredients for toner which is black crystalline particle with resin. Its average radius is 0.2~0.3㎛. It requires highly careful quality control as a critical factor that determines toner?s main attributes such as clearness, consumed quantity and efficiency of copying.

Saehan Media Co., Ltd started development of magnetite for toner in 2000 based on composition technology of Iron Oxide for audio, video tape and quality system. It succeeded in commercializing magnetite for toner in 2001 and now is extending sales in the world diversifying products of magnetite for toner.

Magnetite for video tape

SMT-01S
SMT-01S is used to produce toner for laser printer.
It generates high resolution due to its low coercive force and even magnetism distribution.
