Accoseal系列软木橡胶-可靠且应用广泛的密封材料

Accoseal 是一系列市场知名且广泛指定的基于软垫圈技术的密封材料,在汽车密封环境中具有悠久的历史,同时提供具有成本效益的最终产品定制和制造选项。

软木和精选橡胶的独特混合物产生了用于软垫圈密封的材料,由于减少了侧流,允许更大的接触面积和更高的压缩比,从而保证有效的密封屏障,防止潜在的法兰表面缺陷、扭曲和泄漏路径。

材料一致性

在冲压钢或轻质组件中,Accoseal 软木橡胶材料特别有用,能够以较小的紧固件负载和最小的硬件变形进行压缩,从而实现整体优化的系统设计。与其不可压缩的对应物(如橡胶)相反,它的受控侧流允许凹槽组装而无需余量(无挤出现象)。

耐化学性

Accoseal® 产品具有针对汽车应用介质(如燃料、润滑剂和冷却剂)的广泛特性。专用等级是 UL 列出的,如 NC710、NC711 和 NC711G,属于 UL157 燃料类别。尤其是我们的环氧氯丙烷级 NC711G 已经在生物柴油和生物乙醇燃料混合物中进行了广泛的测试,成绩显著。
