Shanghai Daoqin Plastics Co., Ltd.

        2019 year 9 month 份, 独山子石化老 ethylene plant/unit rear, production 3840UA, belongs to plastics new product, its property can versus 当于齐鲁石化 production 7149U, 我国滚 plastics industry again new formed 员.

         rotational molding molding also 称旋塑, molding, 旋转模塑, molding and other, is Rotational Moulding, is rotomolding or rotocasting. plastics processing molding methods has multiple, remove Common injection molding, blow molding, extrusion molding and other process outer, rotational molding is plastics products types important processing methods, especially in in molding 方面, rotational molding more tool has advantages.

         rotational molding molding process is will plastics raw materials powder material add mold in, rear 不断旋转 mold add hot mold, this mold inner plastics raw materials in heavy force and hot can function lower, uniform melt coating mold cavity surface upper, rear make mold cooling, demolding rear plastics products is rotational molding products. 近, 随 人们 for rotational molding advantages day understanding, rotational molding industrial in inner accelerated development trend.

         in rotational molding raw materials 方面, related industry machine in year 调研 知 currently inner in rotational molding products in, market upper polyethylene (PE) and its composite/compounding material rotational molding rotational molding product ratio/proportion currently 约75%, 99% above rotational molding products raw materials is PE, its in 95% also is non combined rotational molding molding rotational molding grade LLDPE, outer rotational molding polyethylene (PE) material ratio/proportion large is: LLDPE is 65%, XHDPE(crosslinked polyethylene (PE)) is 2%, HDPE is 10%, LDPE is 5%.

         Domestic raw materials currently has 齐鲁石化 production 7149U, 7151U, 扬子石化 production YLR-3505, 独山子石化 3840UA.

         from in 显示, 2018-2019 year inner plastics price obvious high 于普通线 property, price 差距逐步 expand large, 2019 year relatively 普通线 property high 50-850元/吨. currently inner polyolefin industry production capacity 剩, inner 石化一直致 force high product R&D, high field/area, 以获取 relatively large profit. from property 区域 看, due to production capacity 剩, 7042 price year 一直处于 lower 行通道, decrease profit. property industry, in recent years, R&D main/primary direction in in C8线 property, metallocene, plastics and other, its in plastics is separation 支, year R&D relatively more.
