Moulding material composition specially intended for sanitary appliances such as plastic material sinks, baths or wash-basins, likely to be moulded underhigh pressure and at high temperature, comprising: - a polyester resin cross-linking in a monomer liquid with a polymerisable vinylgroup: - a thermoplastic non-shrinking polyethylene type polymer soluble in the resin mixture, - an organic peroxide catalyst to trigger cross-linking of the resin by the provision of free radicals during their destruction at high temperature; - reinforcement fibres such as glass fibres to ensure the rigidity of the cross-linked material, - a component stripping agent such as calcium or zinc stearate, characterised by the fact that it contains fillers selected from: 1°/ chemically coated soda calcium glass micro-beads, 2°/ calcium carbonate in its marble crystalline form with or without pigment coating, to reduce the glass fibre deterioration and obtain a sanitary appliances productresisting abrasion, heat and water. Application in the field of the sanitary appliances industry and more particularly moulded components for products serving as products for use as bathroom or kitchen equipment, such as sinks, baths or wash-basins.
