电子电气产品主要使用阻燃材料,以确保在电气故障引起的火焰点燃情况下具有良好的性能。几十年来,卤素基材料以高性能和成本效益着称,但 ROHS 强调了二十年前第一代卤化阻燃剂的毒性,最近一些氯化和溴化阻燃剂被列入 Reach SVHC 清单和整个 BFR /CFR 系列包含在 IEC 62474 数据库的标准 3 列表中。此外,施耐德电气还收到来自世界某些地区,主要来自欧洲的对无卤产品的市场需求。此外,当技术解决方案确实存在时,施耐德电气正在考虑用非卤化替代品替代卤化阻燃剂基材料的可能性,以避免未来可能面临限制的昂贵材料认证。自本世纪初以来,这些替代品正在缓慢改进,但在某些情况下,这些替代品在成本、脆性或腐蚀性方面仍面临一些缺点。仍需通过研发研究改进替代性,寻找基于协同效应或技术组合的突破性解决方案,而不是渐进式创新。
E&E products are mainly using flame retarded materials to ensure a great behavior in case of flame ignition induced by electrical fault. Halogen based materials are known from decades to be highly performant and cost efficient but ROHS highlighted the noxiousness of first generation of halogenated flame retardant twenty years ago and more recently some chlorinated and brominated flame retardants were included in Reach SVHC list and the whole BFR/CFR families were included in criteria 3 list of IEC 62474 database. In addition, Schneider Electric is receiving market requests for Halogen Free products from some part of the world and mainly from Europe. Also, Schneider Electric is considering the possibility to replace halogenated flame retardant based materials by non-halogenated alternatives when the technical solution does exist to avoid expensive qualification of materials which may face restriction in the future. These alternatives are slowly improving since the beginning of century but, in some cases, the alternatives are still facing some drawbacks in term of cost, brittleness or corrosivity. R&D studies are still required to improve the substitution and find breakthrough solutions based on synergetic effects or mix of technologies instead of incremental innovation.
