Abstract:
The present invention relates to a process for producing a pelletized stabilizer mixture for halogen-containing plastics, comprising the following steps: (a) heating, at from 40 to 100° C. in an extruder or kneader, a mixture comprising (A) at least one lubricant, (B) at least one substance having stabilizer activity, and (C) auxiliaries and additives, where at least 1% by weight of all of the substances, based on the total amount of the mixture, has a melting point below 100° C., (b) forcing the material through a pelletizing die, (c) carrying out die-face pelletization under water, (d) transporting the pelletized stabilizer mixture away in a stream of water, (e) extracting the pelletized stabilizer mixture from the water, and (f) drying the pelletized stabilizer mixture. The present invention further relates to pelletized stabilizer mixtures producible therefrom, and also to use of these.
