铁路工业

要保障铁路运输的顺畅,相应设备的部件就必须拥有高度的耐久性、可靠性和持续使用性。瓦克的有机硅以独特的韧性、稳定性及耐久性组合,能够满足此处的严苛要求。

瓦克有机硅被广泛应用于轨道交通工具的内内外外,如,电缆、连接车厢的波纹管、门窗密封条,或用来驱动和调控铁路运行的电气技术部件。

瓦克现有产品组合中经认证的固体及液体硅橡胶,能够满足对轨道交通工具大部分现行的,尤其是R22和R23的消防要求。

优势:

  • 阻燃
  • 烟气毒性低
  • 过氧化物交联
  • 符合DIN EN 45545-2标准

应用领域:

  • 安装用窗户密封件、窗玻璃密封件
  • 门的密封件
  • 连接车厢的波纹管
