ABSTRACT:
Disclosed is a composition for injection moulding which is composed of a sinterable powder comprising at least one metal or alloy and a binder. The binder contains from 10 to 80% by weight of a low-density polyethylene from 10 to 80% by weight of a paraffin wax and from 5 to 35% by weight of a boric acid ester. The ratio of the sinterable powder to the binder in the composition is from 30 to 70% by volume of the former and from 70 to 30% by volume of the latter. The binder can be removed from the green body to be prepared by injection-moulding the composition unexpectedly rapidly without interfering with the properties of the final product sintered.
