Product Description:

Mica insulator is an entirely mineral material that basically consists of mica and glass- a binding agent that can be vitrified by fusion. These elements are mixed and combined in powder form, and then heated under pressure: the particles of glass when they melt, cover the flakes of mica to form a compact and hard mass.

Glass-mica compounds hold a privileged position among the wide variety of insulators offered to the electrical industry. They are positioned by their temperature of use between plastics and ceramics but they possess the ability to be moulded and to be machined like the former but with the hardness and indestructible qualities of the latter. Mica insulator adds a series of physical and chemical properties to these practical advantages which makes it an entirely exceptional insulator.

Mica insulators can be used for high speed train break resistor, as ideal insulation materials.
We provide various types of insulator, R-M52 and R-M259 are two of them. The specification and characteristics are displayed as following tables.
