5 colorant foam products generally are colored, it is necessary to add a coloring agent in the formulation to the color. China EVA foam product palette can be used toner, colored plastic, of course, better to use masterbatch. MS product cannot use computer color, probably because this thing is too big foam front color change,China EVA foam the computer is also equipped with immortality.

China EVA foam Generally speaking, there are three processes. Traditional large flat foam, small China EVA foam and injection mold.

Traditional large flat foam are generally small factories now use this. Machinery and equipment costs are relatively lower. This process is made out of sheet metal,China EVA foam and then through punching, milling and other processes to make products. Foaming conditions are relatively fixed, the temperature at 160-170, the time determined by the mold thickness, generally 90-110 seconds / MM, pressure 150KG / square CM. $ V) WOaE.

Small foam mold this process is mainly used in the shoe on. Sports shoes do the second first foam midsole. Enhancing the granulation according to the formula,China EVA foam weighed and placed in a good mold, foaming out that the general appearance of shoes. The difficulty of this process is symmetrical mold and formulations,China EVA foam would be difficult to control both magnification and hardness. Size is often qualified, hardness is not enough. Hardness enough size too small.
