有机硅、硅-有机杂化物和硅烷

一系列用途广泛的材料,可针对众多要求严苛的客户应用进行定制

硅基材料具有多种形态(气体、液体、凝胶和固体),其性质与有机基产品显著不同。硅烷和有机硅可轻松配制成具有独特的性质和性能的可固化组合物,还可通过有机功能进行改性,以定制源自无机和有机特性组合的特点,从而实现各种重要的应用。

材料背后的科学

硅烷和有机硅之所以与众不同,是因为富含于地壳中的硅原子(例如沙子,也称为石英)。通常,这些材料中的硅原子与氧原子和主要来自甲醇的简单有机成分结合在一起。硅-氧含量的增加使这些材料更像“玻璃”,从而提高热稳定性、耐久性和实现“固态”形态;硅-有机含量的增加使这些材料更像“有机物”,有助于实现独特的表面特性、防水性和“流体”形态。有机硅的性质和形态取决于这些成分的平衡。将更复杂的有机基团附着在这些基本结构上,就能形成“硅-有机杂化物”,带来一系列非凡的性质和社会效益。

功能和优点

与有机基材料相比,硅基材料通常可实现要求更苛刻的应用,从在极端温度下运行的应用到在恶劣环境条件下长期运行的应用,不胜枚举。它们用作添加剂,可提供表面活性、防水性以及出色感官体验等,使有机硅技术成为实现为我们的日常生活添彩的各种应用的关键因素。
