医疗器械

ELASTOSIL®和SILPURAN®有机硅弹性体整体性能独特，是医疗应用的理想选材。这种纯净的材料具有众多优势，可消毒，化学及物理稳定性优异，无需额外添加稳定剂仅为其中三种。

瓦克的ELASTOSIL®或SILPURAN®有机硅弹性体能够为医疗技术领域各种复杂程度的高敏感应用提供令人满意的解决方案。

可用于挤出成型工艺的固体硅橡胶可主要用来生产制药及医疗用软管，包括：

  • 引流管、蠕动软管、呼吸软管
  • 喂食软管
  • 导尿管
  • 输液管

用注射成型或压缩成型工艺加工而成的液体及固体硅橡胶可用来生产：

  • 垫片
  • 气囊
  • 阀门
  • 隔膜
  • 过滤膜和薄膜
  • 呼吸面具、呼吸波纹管及呼吸枕
  • 工具手柄
  • 消毒盘垫
  • 医疗用品
  • 锁闭器及塞子
  • 医疗线缆

挤出成型

横头挤塑机简图

硅橡胶在这种连续式生产工艺中被压入可调整挤出件造型的喷管，然后固化。此时通常使用螺旋输送机对材料进行调匀、压缩和排气，同时施以所需压力，以制成医疗及制药工业所需的软管等产品。

注射成型

如果需要在大批量生产的同时确保产品质量稳定，注射成型工艺便是目前最重要的对有机硅进行加工的方法，可用来将固化及液体硅橡胶制成密封件、薄膜或阀门等产品。瓦克的液体硅橡胶产品以双组分（A/B）形式供货，分20公斤小桶装和200公斤大桶装两种。瓦克为成型应用提供的固体硅橡胶则为单组分或双组分系统，并有室温硫化型和过氧化物固化型可供使用。
