A significant amount of China Clay (Kaolin) is used for filling rubbers to improve resistance to abrasion and strength. To achieve this, the Kaolin must be complete kaolinite without any other impurities. In other words, China Clay is a preferable additive to rubber because of its “booklet” particle structure that enhances the stiffness and mechanical strength of the rubber product through high-quality stress transfer.
In the rubber products industries, kaolin is an affordable substitute for precipitated silica without losing the actual physical properties. The main purpose of adding China Clay in rubber production is to improve tensile strength. Soft China Clays have greater grain sizes and are used where high loading & faster extrusion rate are more essential than mechanical and tensile strength. Hard China Clay imparts high modulus, stiffness, abrasion resistance and tensile strength.
Water-washed clay is nowadays used in applications like cable manufacturing as it offers strong reinforcement and higher volume resistivity. Regular China Clay is used in conveyor belts, footwear, and molds. High-end China Clay is used in tire production.
