Patent number: 6491853Abstract: The present application relates to storage-stable plastics additives which are prepared by cooling a mixture of 99.9 to 10% by weight of molten additive material and 0.1 to 90% by weight of crystalline additive material after a shaping process. The shaping process is carried out by forcing the mixture out of a tool provided with die openings, and cooling can be carried out on a cooled conveyor belt. Even after prolonged storage and/or handling, these plastics additives remain free-flowing and do not stick.Type: GrantFiled: November 6, 1996Date of Patent: December 10, 2002Assignee: Clariant GmbHInventors: Karl Gaa, Günter Nowy, Gerhard Pfahler, Matthias Zäh
