| Menzolit® BMC 0390 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 0390 is a low profile DMC/BMC. Because of its low shrinkage, the material shows good surface quality as well as very low warpage. The product is suitable for applications if a better surface quality is necessary that cannot be achieved with low shrink material. Because of the low shrinkage, tool design is more difficult and the user should take care to allow proper part ejection from mould. Typical applications are housings or covers that call for improved surface quality and dimensional stability. Because of this painting may be desired. Paint adhesion of appropriate paint systems is very good. Chrome plating of punch and cavity surfaces is recommended.&& |
