2. Usage
Active white carbon has very high surface activity. It is also transparency or semi-transparency in some rubber products. So it is very suitable for making light, colorful, transparency and semi-transparency rubber products. In addition, it can be used as separator of latex; anti-precipitating, thickening and thixotropic agent of paint and printing ink; open agent for all kind of plastic film; granulated fertilizer and dispersing agent; carrier of dynamite; adhesive and grinding agent of tooth paste. Also can be used in middle and high-grade puffy.
