Coated expandable polymer particle

摘要

Expandable polymer particles coated with at least one plasticizer, comprises at least one alkyl ester of cyclohexanecarboxylic acid having a boiling point of >= 160[deg] C and/or at least one 10-21C alkane sulfonic acid phenyl ester having a boiling point of >= 150[deg] C. An independent claim is also included for producing expandable polymer particles, in which the coating is applied by spraying or tumbling.
