DongHai Peptizing Agent: How Temperature Shapes Peptizing PerformanceEvery rubber compounder recognises that interplay. The internal mixer heats up, the polymer softens, and the viscosity begins to drop. A Peptizing agent accelerates this molecular breakdown, but its activity does not remain constant across all temperatures. YG-1, operating under the DongHai brand since 1985, formulates processing aids that respond to the thermal conditions inside the mixer. The...0 Commentarios 0 Acciones 851 Views 0 Vista previa
