欧洲的统计数据显示，每百万台电视机每年发生325次大火，而在美国只有6台。这样做的主要原因是，旧大陆上的电视外壳通常仍然是由几乎没有火焰的材料制成的。亚博网站下载在美国，使用具有V-0分类的材料，符合美国消亚博网站下载防安全标准UL94。
The risk of fire produced by televisions and IT equipment is now increasingly a focus of attention for the media and the public. The International Electrotechnical Commission (IEC) is also responding to the growing safety demands, with the IEC TC 108 - the standards committee with global responsibility for this area - currently laying down new requirements for flame retardance in TV sets. These can already be met by Bayblend® FR grades, flame-retardant polycarbonate (PC) blends from Bayer MaterialScience AG, and special grades of the Bayer MaterialScience polycarbonate Makrolon®.
“ IEC TC 108的目的之一是更有效地保护电视机免受外部点火源的保护，例如燃烧的蜡烛已经推翻了，”
explains Michael Halfmann, fire safety expert at Bayer Industry Services.
Some 12 to 20 percent of all TV fires do not originate in the set but from an external fire source. The new standard therefore specifies areas of a TV set that can be reached by the flame of a candle that has fallen over. The TV must not catch fire in these areas even if it is exposed to the flame for three minutes.
"Our flame-retardant PC/ABS blends and PC grades do not just conform to IEC standards. They can also be used without any problems as a housing material that conforms to the WEEE and RoHS EU directives," says Guido Nachtigäller, Senior Sales Manager for the IT industry atBayer MaterialScience。WEEE代表“废物电气和电子设备”，并指出必须从二手电气和电子设备中除去含有溴化火焰的塑料，并分别app亚博体育处置。“电气和电子设备中某些危险物质的使用限制”（ROHS）指令禁止在电气和电子设备中使用某些溴化化学物质。app亚博体育Bayblend®FR（FR = Flame-Nardant）和Makrolon®相关等级的Flame-Nardant包装不含溴，氯和锑。
例如，长期以来，PC/ABS混合物是用于打印机，计算机，监视器和电视机的住房材料，因为它们具有出色的机械性能，例如高度稳定性，刚度高以及在较大温度范围内的出色韧性。此外，它们很容易满足现有的照明要求，以便在内部使用。
Bayblend® FR 3005 HF is especially well suited for flame retardant TV housings and other large parts with thin walls as it is particularly free-flowing and can be processed extremely cost-effectively.
诸如Makrolon®6557之类的火焰 - 雷力PC等级可用于生产透明的外壳。例如，飞利浦使用Ambilight™技术使用两种类型的材料，用于其宽屏平板电视。在集合的侧面生成光，以补充屏幕上的颜色和光强度，并通过由火焰 - 耐药的makrolon®制成的半透明条散发到周围区域。该灯可以营造出氛围，提供更轻松的电视观看，并增强主观图像对比度。飞利浦Ambilight™电视的其余房屋由Bayblend®FR制成。
