Considering EVA FOAM MANUFACTURER crystallinity decreases
Practice has proved that : When the ZnO / AC = 0.1 , the most obvious effect of foaming additives [ 3 ] . Considering EVA FOAM MANUFACTURER crystallinity decreases with VA content , and its crystallization zone temperature above its melting point (i.e., within the limits of its melt ) , the viscosity sharply , which is detrimental to the foam , the cross-linking agent to be added in order to increase its viscosity. The DCP was chosen as a cross-linking agent , and select one , 22 divinylbenzene as crosslinking agents.
EVA FOAM MANUFACTURER crosslinked foam process is as follows :
Practice found : Since EVA FOAM MANUFACTURER low viscosity in the materials are mixed, kneaded and process can be omitted , only mixing step feeding method .

2 Results and discussion
Basic formula [ mass ( parts ) ]
EVA FOAM MANUFACTURER: 100; 1, 22 divinylbenzene : 0.5; DCP: 0.5; Hst: 1.0; ZnO: 1.5; AC: 15
2.1 DCP amount of foam on the impact of EVA FOAM MANUFACTURER
EVA FOAM MANUFACTURER, Hst the quantitative , Zn / PAC ratio unchanged , DCP is a variable, as the crosslinking agent system 1 , 22 , divinyl benzene, with the amount of DCP to maintain a certain ratio to prepare the sample and measuring its performance.
