PEG-4000 (Rubber Processing & Release Aid)
Polyethylene Glycol 4000 (PEG-4000) is a multifunctional rubber processing aid that improves the dispersibility of fillers, especially carbon black and silica, by coating hydrophilic surfaces and reducing filler agglomeration. In silica-filled compounds, PEG-4000 deactivates acidic silanol groups that would otherwise retard the cure system and absorb DPG. It also acts as an internal mold release agent and extrusion lubricant in various rubber compounds.
