摘要:
The invention relates to the preparation of a divided solid composition comprising a talc powder at least a fraction of which consists of grains of talc bonded together in the form of aggregates whose average size is greater than that of said grains of talc. As well as being highly compatible with a large number of thermoplastic resins and having a high talc content, at least of the order of 75%, a divided solid composition obtained according to the invention can be dispersed into fine talc particles in thermoplastic materials during the shaping of these thermoplastic materials (processes with low shear, such as injection moulding, extrusion of sheets/films, etc.) using conventional techniques and equipment. The invention accordingly permits the production of thermoplastic articles loaded with talc without having to use expensive composites (or compounds).
