China’s 1-hexene copolyethylene market status and analysis of major companies in 2022
Polyethylene is an important synthetic resin with the characteristics of easy processing and molding, high thermal decomposition temperature and excellent comprehensive properties. At present, the comonomer types of polyethylene mainly include 1-butene, 1-hexene and 1-octene. Among them, butene copolymerized polyethylene is the variety with the largest production volume in the world, and 1-hexene copolymerized polyethylene is the fastest growing variety. Fast varieties, newly developed PE products abroad mostly use 1-hexene as comonomer.
The “2022-2026 1-Hexene Copolymerized Polyethylene Industry In-depth Market Research and Investment Strategy Suggestions Report compiled and released by the Industrial Research Center 》 shows that 1-hexene is a kind of α-olefin with good impact resistance, tear resistance and tensile strength. It is mainly used in the production of linear low-density polyethylene (LLDPE), high-density polyethylene ( HDPE) and polyolefin elastomer (POE) comonomer. Linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE) produced with 1-hexene as comonomer have better tensile strength, rheology, and rapid resistance than 1-butene copolymer resin. And slow cracking and impact resistance, suitable for the production of packaging films and agricultural covering films. Since the 1990s, foreign polyethylene manufacturers have favored using 1-hexene and 1-octene instead of 1-butene to produce high-quality polyethylene products.
The production methods of 1-hexene mainly include wax cracking method, alkane dehydrogenation method and low carbon olefin (ethylene, propylene) oligomerization method. Among them, 1-hexene obtained by oligomerization of low carbon olefins (ethylene, propylene) has better purity and color.
For a long time, China’s high-end 1-hexene products have relied on imports. In order to break the foreign technology monopoly, the Chinese government has paid more attention to 1-hexene products. Among them, the “13th Five-Year Plan” development guide for the petrochemical industry clearly mentioned that it is necessary to accelerate the acceleration of high-carbon LAO copolymer monomers such as hexene-1 and octene-1. body research and development work.
Currently, the major global producers of 1-hexene copolyethylene include ExxonMobil Chemical Company, Eastman, Chevron Phillips Chemical Company, Dow Chemical, Basel, Samsung Total, Mitsui Chemicals, etc. ExxonMobil is the world’s leading polyethylene manufacturer with a variety of polyethylene product models. Among them, the ExceedTM metallocene polyethylene series products are produced using 1-hexene as a copolymer monomer in gas-phase polymerization industrial equipment. Metallocene linear low-density polyethylene (mLLDPE) produced by Enable; the second generation of metallocene polyethylene introduced long-chain branched products called Enable has good processing performance and easy molding. Dow Chemical is the world’s major polyethylene resin supplier, producing LLDPE and mLLLDPE film resin products using 1-hexene as a comonomer.
At present, my country’s Qilu Petrochemical, Maoming Petrochemical, Shanghai Secco Petrochemical, Daqing Petrochemical, Guangzhou Petrochemical, Yangzi Petrochemical, etc. all have the ability to use 1-hexene as a comonomer to produce HDPE or LLDPE, but they are limited by the insufficient supply of 1-hexene. , the production of related brand products is restricted.
Industry researchers said that in recent years, China’s polyethylene products have continued to grow rapidly and have become the world’s largest Polyethylene producing countries. As a high-end polyolefin product, 1-hexene copolymerized polyethylene products have great market potential and promising market prospects.
