MICAVER® is a mica-glass insulating material with many applications in the rail sector such as insulators and stand-off insulators. They are produced by over-moulding metallic inserts for use in rheostatic components for brakes, heating elements, electrical cable fixtures. MICAVER® has a very long life cycle, reducing maintenance costs for the railways companies. MICAVER® is used world-wide in locomotives, high speed trains and metros.
Saint-Gobain Quartz SAS is for more than 50 years a leading supplier of MICAVER® in the railways industry.
MICAVER® exists now in various shapes for long creeping distance electrical insulation.
MICAVER® compounds holds a priviledged position among the wide variety of materials available. They are positionned between plastics and ceramics in terms of temperature resistance, have the ability to be moulded like plastics, have the impact strength of plastics, have the durability, UV resistance and fire resistance of ceramics.
Saint-Gobain Quartz has recently developped a new grade called MICAVER® HT; it can be used at higher temperature up to 700°C and its color is white.
The MICAVER® HT glass ceramic is also machinable. This enables to produce low quantities or samples by machining as well as bigger series by moulding.
