白炭黑是目前最常用的补强填料之一,因为它能增强高技术橡胶产品(尤其是轮胎和橡胶工业制品)的性能。据报导,与传统炭黑相比,白炭黑能更好地平衡轮胎性能,特别是滚动阻力、生热性和湿路面抓地力,因此是轮胎炭黑填料的一种良好替代物。然而,在橡胶胶料中采用白炭黑也会带来某些缺点,这通常影响加工和硫化等方面。

Silica is currently one of the most commonly used reinforcing fillers because it enhances the performance of high-tech rubber products, especially for tires and rubber industrial products. It has been reported that silica provides better balance of tire performance than conventional carbon blacks, particularly rolling resistance, heat build-up and wet road grip and is therefore a good alternative to tire carbon black filler. However, the use of silica in rubber compounds also brings with it some disadvantages, which often affect processing and vulcanization.
