Product Description
Menzolit® BMC 2500 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 2500 is a special BMC for high voltage isolating applications. The glass content is set to a level that combines good mouldability with good strength and stiffness properties. The fire retardancy level HB according to the UL 94 is achieved. The electrical properties are improved to have exceptional high isolation properties. When moulding this material, a high moulding pressure is important to achieve a well densified material matrix to guarantee high voltage applications. Typical applications are isolating components in high voltage applications.
