## Abstract

The present invention relates to an additive to improve processability in the manufacture of ethylene, propylene and diene compounds, comprising Ethylene Propylene Diene type M (EPDM) and paraffinic mineral oil, and a method for producing additive to improve processability in the manufacture of ethylene, propylene and diene compounds, comprising the steps of: a) heating one fifth of paraffinic mineral oil until reaching a temperature of 100° C.±5° C.; b) once the paraffinic mineral oil portion reaches the indicated temperature, add Ethylene Propylene Diene type M (EPDM), maintaining constant temperature and stirring until complete dissolution to generate Mixture 1; c) Add the remaining four fifths of the paraffinic mineral oil to Mix 1 and continue stirring until dissolution is complete while maintaining the temperature; and d) once complete integration of Blend 1 and the remaining four fifths of the paraffinic mineral oil is achieved, filtering the additive to remove any remnants and/or impurities.
