NEW DEVELOPMENTS AND IMPROVEMENTS FOR BROMTNATED FLAME RETARDANTS

摘要

Bromine is used as the basic element for some of the most effective flame retarding agents available to the plastics industry today. They are used to protect against the risk of accidental fires in a wide range of Electrical and Electronic Equipment (EEE). Brominated flame retardants (BFRs), as all flame retardants, act to decrease the risk of fire by increasing the fire resistance of the materials in which they are applied. There is a perception that BFRs affect adversely the end-of-life management of plastics through formation of Poly Brominated Dioxins and Furans (PBDD/F). In fact, there exists a wide range of data and practical experience demonstrating that the end-of-life management of plastics containing BFRs is fully compliant with legislation setting the strictest limit values for PBDD/F and is fully compatible with an integrated waste management concept. On the other hand, the production chain for fire-retarded plastics is continuously looking for improvement at all steps of their life cycle. The SaFRon series is materializing DSBG's contribution to address these existing and future market needs. It is more a concept than a product line and offers to the market a partnership with the new dimension of sharing know-how, time and costs between supplier and user during the development stage. The bromine branch organisation EBFRIP has investigated recycling and recovery of these plastics with BFR's thoroughly the last 5 years. Mechanical recycling, co-combustion and feedstock recycling are the main projects.
