Procedure for recovering waste from a polymeric composition that includes a peroxy crosslinking agent

摘要

A process for recovering waste from a polymer composition that includes at least one peroxide curable polymer and at least one peroxide crosslinking agent, comprising mixing the waste with at least one antioxidant agent suitable for sulfur vulcanized elastomeric compositions, at a lower temperature that the decomposition temperature of the at least one peroxy crosslinking agent; wherein the at least one antioxidant agent is selected from: secondary phenylamines, and low molecular weight hindered phenols having a molecular weight of less than 1000; wherein the method includes using the recovered polymer composition as a filler material for electric cable cores.
