AKROCHEM Accelerator R is recommended for uses where a non-blooming or non-staining sulfur donor is required. It contains approximately 27% sulfur, which is released at curing temperatures. Additional acceleration by thiazoles, sulfenamides, or thiurams is recommended. It can be used for EV or semi-EV compounds as a partial or complete replacement for elemental sulfur. It provides excellent aging resistance in synthetic and natural rubbers, including heat and reversion resistance. Accelerator R is also available as Akroform DTDM PM (75). This polymeric masterbatch contains 75% Accelerator R and has a specific gravity of 1.20. Polymer bound or encapsulated dispersions are a proven means of upgrading plant safety, efficiency, quality and raw material control. |
