Gap Filler 1400SL液體空隙填充材料擁有熱傳導(dǎo)和硅基材料特點。這種材料擁有非常低的粘度，從而使得其會自動流平和自動填充空隙，導(dǎo)致熱傳導(dǎo)更佳。液體材料能夠滿足各種不同的間隙形狀厚度，而且在位移時應(yīng)力極小，可以解決個別應(yīng)用中對界面材料厚度和形狀的需求。Gap Filler 1400SL間隙填充導(dǎo)熱材料應(yīng)用于不需要牢固粘接結(jié)構(gòu)的熱傳導(dǎo)界面。
典型的應(yīng)用包括：汽車電子.電信.封裝半導(dǎo)體和磁性元件與散熱片.有機(jī)硅敏感應(yīng)用.照明.電力供應(yīng)
