Study on Curing Properties of Ployether PU Rubber

Effect of different vulcanization systems on the properties of ployether PU rubber,is investigated with the PUR cured by sulfur vulcanization systems and DCP vulcanization systems.The results showed that sulfur vulcanization systems could increase T10,T90,MH,but decrease ML,enhance the damping of PU rubber,while DCP vulcanization systems could distinctly decrease compress set and the elongation at break.
