| Résumé : |
Since August 2015, the flame retardant hexabromocyclododecane (HBCD) may not be used for insulating materials. After many years of research and development, an adequate substitute has been developed, which is suitable for extruded as well as expanded polystyrene foams. It is neither toxic nor bioaccumulative according to the European REACH regulation and the Stockholm Convention's worldwide POP (persistent organic pollutant) list. |

- Balancing Act between regulations, environment, and fire protection
- Licensed protection of the flame retardant
- Comprehensive environmental testing
- FIGURES : The chemical structure of the polymeric flame retardant is a brominated styrene-butaniene-styrene block copolymer with a molecular weight of more than 60 000 g/mol and a 1.2 isomer fraction of >50%. The higher molecular weight reduces the risk of migration through cell membranes - 2. Compared with the new development, the previously used and no longer permitted hexabromocyclododecane (HBCD) has considerably lower molecular weight of 642g/mol - 3. The new sustainable flame retardant, shown here in pure form as a flm, is itself a plastic or polymer with thermoplastic properties
- TABLE : Except from the EPA risk report on HBCD substitute materials and their health and environment-related properties |
