| Menzolit® SMC 2400 is a sheet 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 compression moulded in heated steel moulds. It is recommended to work with chrome plated tools. The product contains no halogens. Menzolit® SMC 2400 is a SMC with extraordinary fire retardancy. The glass level has been selected to combine mouldability with strength and stiffness properties. The fire retardancy is especially high, and the material is virtually nonburnable. In case of fire smoke is released to a small extent. Smoke is, except for carbon monoxyde non-toxic! This makes SMC 2400 very suitable for railway interior or exterior applications, like wall panels, window frames, lugage bins, seat shells and structures or similar rail way components. Fire safe furniture or sanitary furniture on ships, trains or prison cells are another typical use. Within the electrical industry it is used for arc quenching chambers or switch gear components that are exposed to high power switching operations and resulting electrical arcs (peak loads of temperature and fire).&& |
