COMPRESSION PRESS FOR A PULVERULENT MATERIAL WITH A NON-STICK SURFACE AND A PRESS FITTED WITH SUCH A PUNCH

摘要

The present invention relates to the production of a compression press for a pulverulent material for a tablet press comprising a preformed active part intended to be in contact with said material with a view to compressing said material, characterised in that said active part is produced from a material having a surface whereon are grafted, by covalent bonding, radicals comprising molecular groups having a non-stick effect. Advantageously, said molecular group is a fluoroalkyl group, for example of the CnF2n+i type, n being an integer higher than or equal to 1.
