| Menzolit® BMC 0400 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 nor any heavy metals. Menzolit® BMC 0400 is a low profile DMC/BMC for automotive applications. It fulfils the requirements of the automotive industry regarding painted body panels including reduced C-emissions. For highest surface quality we recommend processing on mirror finish chrome-plated steel moulds. The material shows a high thermal resistance for on-line painting at 190- 200 °C. Adhesion of paint is excellent. The material doesn’t shrink during moulding, it even expands. Therefore warpage is reduced and dimensional stability is excellent.&& |
