电绝缘材料行业

有机硅树脂尽管不为肉眼所见,却是许多电绝缘材料和复合材料不可或缺的组分。例如,瓦克SILRES®系列的产品被作为耐高温的憎水性电绝缘基料用于许多日常用品,而这些日常物品使用起来是如此可靠而让人放心,大家都已经“习以为常”了。
无论是烤面包机、吹风机、热水壶、洗碗机、洗衣机,还是有轨​电车,瓦克能够为这些最终应用领域所需电绝缘材料和复合材料提供对口的有机硅产品。

用硅树脂粘合的云母、玻璃纤维或矿物纤维基层压制品能够在持久承受极端温度的同时,保持电气性、憎水性及高度的机械强度。

SILRES®硅树脂是预陶瓷制品,以及基于无机基质材料的陶瓷模压制品或烧结模压制品出色的基料。

优势:

  • 在大跨度的温度和频率范围内具有优异的电绝缘性
  • 耐温性强
  • 憎水,对湿气或潮气的抗耐性强
  • 具有阻燃性,在燃烧时不会释放有毒气体
  • 热解后可转化为电气绝缘后续产品
  • 耐候性和耐辐射性持久
  • 耐介质

为此,基于矿物填料的防护涂层和填料需要使用像SILRES®系列的硅树脂这样耐热、阻燃、电绝缘的基料。

出于美观考虑,防护涂层可用有机硅光泽漆进行“修饰”。

优势:

  • 耐温性强
  • 电绝缘性出色
  • 热解后可转化为电气绝缘后续产品
  • 具有阻燃性,燃烧时不会释放有毒气体
