Experimental-numerical analysis of kaolin-silicone biocomposites / Ahmad Faridzal Rosli

Kaolin is one of the widely uses clay in many applications such as cosmetics, pottery and ceramic, adhesives and tiles. Furthermore, kaolin is also being used as a filler for several applications for example filler for paper coatings, paint and cosmetics, because of its inertness to skin, low viscos...
