| description | PURPOSE: A producing method of high density polyethylene is provided to secure the high parison stability, and to prevent the thickness deviation of the upper side and the lower side of a molded product using the polyethylene. CONSTITUTION: A producing method of high density polyethylene comprises the following steps: dispersing 0.001~2.5 parts of peroxide by weight to 100 parts of low density polyethylene by weight with the density of 0.900~0.925 grams per cc; cross-linking the low density polyethylene in which the peroxide is dispersed; mixing 100 parts of high density polyethylene resin by weight with the density of 0.935~0.965 grams per cc produced by a ziegler-natta catalyst, and 1~45 parts of the cross-linked low density polyethylene by weight; and melt-extruding the mixture from the previous step. |
