HDPE是一種由乙烯共聚生成的熱塑性聚烯烴。雖然HDPE在1956年就已推出，但這種塑料還沒達到成熟水平。這種通用材料還在不斷開發其新的用途和市場。我國國內高密度聚乙烯（這里的高密度聚乙烯不包括全密度聚乙烯裝置生產的高密度聚乙烯）的生產商有中石油、中石化、中海油三大企業，截至2006年年底，屬于中石油的高密度聚乙烯裝置有4套，即蘭州石化高密度聚乙烯裝置、大慶石化高密度聚乙烯裝置、遼陽石化高密度聚乙烯裝置、吉林石化高密度聚乙烯裝置
HDPE is a polyolefin produced by copolymerization of ethylene thermoplastic. Although HDPE in 1956 has been launched, but the plastic hasn't reached the mature level. This versatile material continues to develop its new uses and markets. China's domestic HDPE (high density polyethylene high density polyethylene here do not include the full density polyethylene device production) producers in the oil, Sinopec, CNOOC three large enterprises, as of the end of 2006, high density polyethylene device belongs to the oil in 4 sets, namely Lanzhou Petrochemical HDPE device, Daqing Petrochemical HDPE device, Liaoyang Petrochemical HDPE device, Jilin Petrochemical HDPE device
高密度聚乙烯通常使用Ziegler-Natta聚合法制造，其特點是分子鏈上沒有支鏈，因此分子鏈排布規整，具有較高的密度。該過程在管式或釜式低壓反應器中以乙烯為原料，用氧或有機過氧化物為引發劑引發聚合反應。
High density polyethylene usually use Ziegler-Natta manufacturing polymerization, which is characterized by no branched chains, therefore molecular chain arrangement of regular, have a higher density. In the process of tubular or kettle type low voltage reactor to ethylene as raw material, with oxygen or organic peroxides as initiators and polymerization.
高密度乙烯屬環保材質，加熱達到熔點，即可回收再利用。須知塑膠原料可大分為兩大類：“熱塑性塑膠”（Thermoplastic）及“熱固性塑膠”（Thermosetting），“熱固性塑膠”是加熱到一定溫度后變成固化狀態，即使繼續加熱也無法改變其狀態，因此，有環保問題的產品是“熱固性塑膠”的產品（如輪胎），并非是“熱塑性塑膠”的產品（如 塑膠棧板 注:棧板在港澳被稱為“夾板”)，所以并非所有“塑膠”皆不環保。
High density polyethylene belongs to the environmental protection material, heating to the melting point, can be recycled. For plastic materials can be divided into two categories: "thermoplastic plastic" (Thermoplastic) and "thermosetting plastic" (Thermosetting) ", thermosetting plastic" is a cured after heated to a certain temperature, even if the heating can not continue to change its state, therefore, environmental problem is the product of the "thermosetting plastic" products (such as tire), is not "thermoplastic plastic" products (such as plastic pallets note: pallets in Hong Kong and Macao is called "splint"), so not all the "plastic" are not environmental protection.

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.

This is the main determinant of HDPE characteristics, while the 4 variables mentioned did play interbs. Ethylene is a polyethylene the main raw material, the other comonomers few, such as 1 butene, one or 1 l was a octene, often used to improve the perbance of polymer, HDPE, more than a few monomer content of less than 1% - 2%. Copolymerization of monomers were slightly reduced the crystallinity of polymers. This change in general by the density to measure, there is a linear relationship between density and crystallization rate. American general classification according to the provisions of ASTM D1248, the density of HDPE in 0.940g/. C or above; medium density polyethylene (MDPE) density range from 0.926 to 0.940g/CC. Other classification sometimes the MDPE is classified as a HDPE or LLDPE. Homopolymers with the highest density, maximum stiffness, anti permeability and the highest melting point is good, but generally has poor resistance to environmental stress cracking (ESCR). ESCR PE anti by mechanical or chemical stress induced cracking ability. Higher density generally improved mechanical strength, such as tensile strength, stiffness and hardness; thermal properties such as softening point temperature and heat debation temperature; anti permeability, such as air permeability and water vapor permeability. Low density to improve the impact strength and ESCR. The polymer density is mainly affected by the comonomer to join, but to a less extent is also affected by the molecular weight. High molecular weight percentage density decreased slightly. For example, homopolymer in a wide molecular weight range with different density.
