MASTER BATCH FOR CERAMIC- OR METAL-POWDER INJECTION-MOLDING, AND METHOD FOR PREPARING SAID MASTER BATCH

摘要

The invention relates to a master batch for molding, including at least one inorganic powder, advantageously ceramic or metal powder, and an organic mixture, advantageously a polymer mixture, including: a stable polymer having high ductility properties and constituting 30 to 90 wt % of the mixture; a lubricant constituting 5 to 50 wt % of the mixture; and a plasticizing polymer constituting 5 to 30 wt % of the mixture. The ratio of [wt % of the lubricant]/[wt % of the stable polymer] is less than or equal to 1, advantageously strictly less than 1.
