梓哲高密度聚乙烯PE管DN90mm全新料生产给水用管PE树脂，是由单体乙烯聚合而成，由于在聚合时因压力、温度等聚合反应条件不同，可得出不同密度的树脂，因而又有高密度聚乙烯、中密度聚乙烯和低密度聚乙烯之分。在加工不同类型PE管材时，根据其应用条件的不同，选用树脂牌号的不同，同时对挤出机和模具的要求也有所不同。pe管分为PE32、PE40、PE63、PE80、PE100五个等级，而用于燃气管和给水管的材料主要是PE80和PE100。我国对聚乙烯管材料没有分级，这使得国内聚乙烯燃气管和给水管生产厂家选择原材料比较困难，也给聚乙烯管材的使用带来了不小的隐患。

Zizhe high density polyethylene PE pipe dn90mm new material produces PE resin for water supply pipe, which is polymerized by monomer ethylene. Due to different polymerization conditions such as pressure and temperature, resins with different densities can be obtained. Therefore, it can be divided into high density polyethylene, medium density polyethylene and low density polyethylene. When processing different types of PE pipes, according to different application conditions, different resin grades are selected, and the requirements for extruder and die are also different. PE pipes are divided into five grades: PE32, PE40, pe63, PE80 and PE100, and the materials used for gas pipes and water supply pipes are mainly PE80 and PE100. Polyethylene pipe materials are not graded in China, which makes it difficult for domestic polyethylene gas pipe and water supply pipe manufacturers to select raw materials, and also brings no small hidden dangers to the use of polyethylene pipes.

主要ABS生产商近期订单增量，预售节奏加快，现货供应余量紧张。但中小下游工厂对当前高价抵触，主流市场拉涨动能减弱，中间商倾向于灵活走单，部分成交趋于灵活，预计明日ABS价格补排除局部小跌，华南地区台湾奇美757主流市场价格参考在17500元/吨左右。

Recent orders of major ABS manufacturers have increased, the pace of pre-sale has accelerated, and the surplus of spot supply is tight. However, small and medium-sized downstream factories are in conflict with the current high prices, the rising momentum of the mainstream market is weakened, middlemen tend to take orders flexibly, and some transactions tend to be flexible. It is expected that ABS prices will supplement and exclude some small declines tomorrow. The price reference of Taiwan Qimei 757 mainstream market in South China is about 17500 yuan / ton.

我国PE在产的企业有30多家，前十企业占国内总产能的近一半。进出口方面，我国聚乙烯树脂进口量呈稳定增长的趋势，出口量在低位波动变化。

There are more than 30 PE enterprises in production in China, and the top ten enterprises account for nearly half of the total domestic production capacity. In terms of import and export, the import volume of polyethylene resin in China shows a stable growth trend, and the export volume fluctuates at a low level.

合聚乙烯英文名称：polyethylene ，简称PE，是乙烯经聚合制得的一种热塑性树脂。在工业上，也包括乙烯与少量 α-烯烃的共聚物。聚乙烯无臭，无毒,手感似蜡,具有优良的耐低温性能(最低使用温度可达-70～-100℃),化学稳定性好,能耐大多数酸碱的侵蚀(不耐具有氧化性质的酸),常温下不溶于一般溶剂,吸水性小,电绝缘性能优良。

Polyethylene is a thermoplastic resin prepared by polymerization of ethylene. In industry, it also includes ethylene and small amounts α- Copolymers of olefins. Polyethylene is odorless, non-toxic and feels like wax. It has excellent low temperature resistance (the minimum service temperature can reach - 70 ~ - 100 ℃), good chemical stability, can resist the erosion of most acids and bases (not resistant to acids with oxidation properties), is insoluble in general solvents at room temperature, has small water absorption and excellent electrical insulation performance.
