It is a special grade of Kaolin clay filler characterized by its plate-like particle structure. This unique morphology enhances the air retention capability of the final product, making it highly effective in improving airtightness. It is commonly used in the radial tire industry, particularly in inner-liners, where excellent air permeability properties are required.<\/p>\n
