Imerys' solutions contribute to the performance of a large number of applications and address four types of use:
functional additives: they are added to the mineral formulation of customers’ products but constitute a minor part of the finished product properties;
mineral components: they are an essential constituent in the formulation of the customer’s product;
process enablers: they are used in customers’ manufacturing processes but are not present in the end product;
finished products: they are used as such, with no subsequent processing by the customer.
