| Menzolit® BMC 2300 is a bulk moulding compound based on unsaturated polyester resin. The product is glass fibre reinforced and contains mineral fillers. In case of fire the product doesn’t melt, neither does it form droplets nor is smoke generation excessive. The material is injection moulded in heated steel moulds. It is recommended to work with chrome plated tools. The product contains no halogens. Menzolit® BMC 2300 is a special BMC with exceptional high fire retardancy. The glass content is set to a level that provides sufficient mouldability with high strength and stiffness properties. Fire retardancy is exceptionally high and the material is not burnable. The high fire retardancy makes it especially suited for switch gear components, for high voltage and high current applications.&& |
