Practice has proved that: When the ZnO / AC = 0.1, the most obvious effect of foaming additives [3]. Considering with VA content CHINA EVA FOAM crystalline decreases, and its crystal zone temperature above its melting point (i.e., within the limits of its melt), the viscosity sharply, which is detrimental to the foam, so to be added the cross linking agent to increase its viscosity. The DCP was chosen as a cross-linking agent, and select one, 22 divinylbenzene as cross linking agents.

1.3 Sample Preparation

1.3.1 Process

Crosslinked CHINA EVA FOAM foam process is as follows:

Practice found: Since CHINA EVA FOAM low viscosity in the materials are mixed, kneaded and process can be omitted, only mixing step feeding method.
