Use of Halogens卤素的使用
• BFRsare added to plastics used in electrical and electronic
equipment (EEE) to slow down or prevent the ignition of fire
溴化阻燃剂添加到电子电气产品中用的塑料里面，以减轻
或防止火灾的发生。
• PVC is used as the base resin for certain cable jacketing
and vibration dampening materials 聚***乙烯以树脂基
形态用在某些线缆的外被和减震材料中。
• Halogenated compounds (chlorinated and brominated)
used as reducing agent in solder flux 卤素化合物，包
括***化物和溴化物，在助焊剂中用作还原剂。
• Polytetrafluoroethylene(PTFE) as a high performance
PCB substrate
更为熟知的聚四***乙烯是高性能的PCB基材。

Halogens in Epoxy Resins
环氧树脂中的卤素
• Most PCB Resins are Epoxies
大多数树脂都是环氧型树脂。
• Epoxy resins contain measurable levels of
Chlorine
环氧树脂中的***含量本身已达到可测得水平
• Additional halogens are added to PCB
laminates through glass sizes, wetting agents,
curing agents and resin accelerators.
卤素还会以其他形式添加到PCB中，例如玻纤胶
料，润湿剂，固化剂，树脂促进剂，等。

Why use Brominated Flame Retardants?
为什么要使用阻燃剂？
• The major human health hazard is fire itself, not
which materials are burning
危害人类健康主要是火灾本身，而非燃烧的物体。
non flame retarded UK-FR standard
• Flame retardants must (EU standard)
balance health,
environment,
performance, cost
阻燃剂的使用必须权衡健
康、环境、性能、成本等
因素。
