如今，在环保壁垒之下，由C8逐渐转型至C6。据统计，2014年整个中国市场消耗的氟化物约为13000-15000吨，而C8产品就占了85%，如此大的用量也充分说明C8优异的防水防油效果。现在，在环保的相关标准限定下，C8产品已经在某些模块限制使用了，取而代之的就是C6。但是，有种观念早已植入大家心里，就是：C6的防水效果始终敌不上C8的。那么，是什么原因导致C6的效果不如C8呢？下面我们主要从3个方面来探讨探讨：
1. The problem of carbon chain length (i.e. fluoride content): fluorine element is embedded in the carbon chain. If there is more fluorine element embedded, the carbon chain will become longer. If the carbon chain is longer, the stability between molecules will also decrease. With strengthening, the stability is strengthened and the ability to resist external dirt and oil stains is also enhanced. �</p
2.布面的洁净程度影响：关于面料表面的杂质，对C6的影响会高于C8，C6在处理前要确定布面的洁净；C8也会有所要求，但是要求并没有C6的要求高。所以布面的洁净程度这个对C6而言至关重要。
3.与配套柔软剂的影响：这也是与碳链的长短有关联的，柔软剂对防水效果都会有影响，只不过说C8的影响小于C6。
综上所述，相信大家对C6防水效果不如C8防水效果也有了一定的了解。
