較高的分子量導致較高的聚合物粘度，不過粘度也與測試所用的溫度和剪切速率有關。用流變或分子量測量對材料的分子量進行表征。HDPE的品級一般具有的分子量范圍是40 000～300 000，重均分子量大致與熔融指數范圍相對應，即從100～ 0． 029g/10min(230℃，2.16kg)。通常地，更高的MW（更低的熔融指數MI）增強了熔體強度、更好韌性和ESCR，但是更高MW使加工
The high molecular weight resulted in higher viscosity of the polymer, but the viscosity and the test temperature and shear rate. By the rheological and molecular weight measurements were used to characterize the molecular amounts of material. The range of molecular weight is HDPE grade is 40000 ~ 300000, the weight average molecular weight and melt index roughly corresponding to the scope, that is from 100 to 0 029g/10min (230 ℃, 2.16kg). Generally, the higher MW (melt index MI lower) enhanced the melt strength, better toughness and ESCR, but higher MW processing
過程更難或且需要更高的壓力或溫度。
Process more difficult or and higher pressure or temperature.
分子量分布（MWD）：PE的WD根據使用的催化劑和加工過程而有從窄到寬的不同。
The molecular weight distribution (MWD): PE WD according to the catalyst and process used and different from narrow to wide.
最常用的MWD測量指數是不勻度指數（HI），它等于重均分子量（MW）除以數均分子量（Mn）。所有HDPE品級的這個指數范圍是4—30。窄MWD提供了在模塑過程中的低翹曲性和高沖擊性。中到寬MWD提供了對多數擠塑過程的可加工性。寬MWD也可改進熔體強度和抗蠕變性。
Measurement of MWD index is the most commonly used irregularity index (HI), it is equal to the weight average molecular weight (MW) divided by the number average molecular weight (Mn). 4 - 30 is the index of all HDPE grade. The narrow MWD provides low warp and high impact during the molding process. In the wide MWD provides most of the extrusion process of machining. The b of MWD can also improve the melt strength and creep resistance

Method for the production of PE is the most common by slurry or gas phase process, there are a few with solution phase processing. All of these processes are made of vinyl monomer, a- olefin monomer, catalyst system (may be more than one compound) exothermic reb and various types of hydrocarbon diluent participation. Hydrogen and catalyst is used to control the molecular weight. A slurry reactor is stirred tank or large loop reactor, a more common, in which the slurry can cycle stirred. When ethylene and a comonomer (as required) and catalyst contact, will b the polyethylene particles. After removal of the diluent, polyethylene particles or powder is dried and additive dosage, the production of pellets. Large reactor with double screw extruder production line, each hour pounds more than the PE40000 production. The development of new catalysts and contribute to the perbance improvement of the new class HDPE. Two kinds of catalyst is the most commonly used chrome oxide Philip based catalyst and titanium compound alkyl aluminium catalyst. Philip type catalyst for producing HDPE in b distribution of molecular weight; molecular weight titanium alkyl aluminium catalyst production of narrow distribution. With the production of narrow MDW complex reactor polymer catalyst can also be used in the production of wide MDW grade. For example, the production of different molecular mass production of two series reactor can produce Shuangfeng the polymer molecular weight, molecular weight distribution of the polymer has a full b domain.

HDPE is a high degree of crystallinity, non-polar thermoplastic resin. The original state of HDPE milky white appearance, with a certain degree of translucent at thin section. PE has excellent chemical resistance properties with the most life and industry. Some kinds of chemicals will produce chemical corrosion, such as corrosive oxidizer (nitric acid) (Er Jiaben), aromatic hydrocarbons and halogenated hydrocarbons (carbon tetrachloride). The polymer is not hygroscopic and has good waterproof steam, and can be used for packing. HDPE has good electrical properties, especially the insulation of high dielectric strength, so it is suitable for wire and cable. Medium to high molecular weight grades with excellent impact resistance, at room temperature even in the -40F low temperature so. The unique characteristics of various grades of HDPE is an appropriate combination of four basic variables: density, molecular weight, molecular weight distribution and additive. Different catalysts are used in the production of customized special properties of polymer. These variables are combined to produce the different uses of HDPE grade; in the perbance of the best balance.
