Significant increase in domestic high-voltage production and narrowing of linear price difference
Since 2020, domestic polyethylene plants have entered a centralized expansion cycle, and the annual production capacity of domestic PE has rapidly increased, with an average annual growth rate of over 10%. The production of domestically produced polyethylene has rapidly increased, with severe product homogenization and fierce competition in the polyethylene market. Although the demand for polyethylene has also shown a growth trend in recent years, the demand growth has not been as fast as the supply growth rate. From 2017 to 2020, the new production capacity of domestic polyethylene mainly focused on low-voltage and linear varieties, and there were no high-voltage devices put into operation in China, resulting in a strong performance in the high-voltage market. In 2020, as the price dif... -

What Are the Different Types of Polyethylene?
Polyethylene is commonly categorized into one of several major compounds, the most common of which include LDPE, LLDPE, HDPE, and Ultrahigh Molecular Weight Polypropylene. Other variants include Medium Density Polyethylene (MDPE), Ultra-low-molecular-weight polyethylene (ULMWPE or PE-WAX), High-molecular-weight polyethylene (HMWPE), High-density cross-linked polyethylene (HDXLPE), Cross-linked polyethylene (PEX or XLPE), Very-low-density polyethylene (VLDPE), and Chlorinated polyethylene (CPE). Low-Density Polyethylene (LDPE) is a very flexible material with unique flow properties that makes it particularly suitable for shopping bags and other plastic film applications. LDPE has high ductility but low tensile strength, which is evident in the real world by its propensity to stretch whe... -
This year’s titanium dioxide production capacity will break 6 million tons!
From March 30th to April 1st, the 2022 National Titanium Dioxide Industry Annual Conference was held in Chongqing. It was learned from the meeting that the output and production capacity of titanium dioxide will continue to grow in 2022, and the concentration of production capacity will further increase; at the same time, the scale of existing manufacturers will further expand and investment projects outside the industry will increase, which will lead to a shortage of titanium ore supply. In addition, with the rise of the new energy battery material industry, the construction or preparation of a large number of iron phosphate or lithium iron phosphate projects will lead to a surge in titanium dioxide production capacity and intensify the contradiction between supply and demand of titani... -
What Is Biaxially Oriented Polypropylene Overwrap Film?
Biaxially oriented polypropylene (BOPP) film is a type of flexible packaging film. Biaxially oriented polypropylene overwrap film is stretched in machine and transverse directions. This results in a molecular chain orientation in both directions. This type of flexible packaging film is created via a tubular production process. A tube-shaped film bubble is inflated and heated to its softening point (this is different from the melting point) and is stretched with machinery. The film stretches between 300% – 400%. Alternatively, the film can also be stretched by a process known as tenter-frame film manufacturing. With this technique, the polymers are extruded onto a cooled cast roll (also known as a base sheet) and drawn along the machine direction. Tenter-frame film manufacturing us... -
The export volume increased significantly from January to February 2023.
According to customs data statistics: from January to February 2023, the domestic PE export volume is 112,400 tons, including 36,400 tons of HDPE, 56,900 tons of LDPE, and 19,100 tons of LLDPE. From January to February, the domestic PE export volume increased by 59,500 tons compared with the same period in 2022, an increase of 112.48%.

The main applications of PVC .
1. PVC profiles PVC Profiles and profiles are the largest areas of PVC consumption in China, accounting for about 25% of the total PVC consumption. They are mainly used to make doors and windows and energy-saving materials, and their application volume is still increasing significantly nationwide. In developed countries, the market share of plastic doors and windows also ranks first, such as 50% in Germany, 56% in France, and 45% in the United States. 2. PVC pipe Among the many PVC products, PVC pipes are the second largest consumption field, accounting for about 20% of its consumption. In China, PVC pipes are developed earlier than PE pipes and PP pipes, with many varieties, excellent performance and wide application range, occupying an important position in the market. 3. PVC film... -
Types of polypropylene .
Polypropylene molecules contain methyl groups, which can be divided into isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene according to the arrangement of methyl groups. When the methyl groups are arranged on the same side of the main chain, it is called isotactic polypropylene; if the methyl groups are randomly distributed on both sides of the main chain, it is called atactic polypropylene; when the methyl groups are arranged alternately on both sides of the main chain, it is called syndiotactic. polypropylene. In the general production of polypropylene resin, the content of isotactic structure (called isotacticity) is about 95%, and the rest is atactic or syndiotactic polypropylene. The polypropylene resin currently produced in China is classified according... -
The use of paste pvc resin.
It is estimated that in 2000, the total consumption of the global PVC paste resin market was about 1.66 million t/a. In China, PVC paste resin mainly has the following applications: Artificial leather industry: the overall market supply and demand balance. However, affected by the development of PU leather, the demand for artificial leather in Wenzhou and other major paste resin consumption places is subject to certain restrictions. The competition between PU leather and artificial leather is fierce. Floor leather industry: Affected by the shrinking demand for floor leather, the demand for paste resin in this industry has been declining year by year in recent years. Glove material industry: the demand is relatively large, mainly imported, which belongs to the processing of supplied mate... -
The 800,000-ton full-density polyethylene plant was successfully started up in one feeding!
Guangdong Petrochemical’s 800,000-ton/year full-density polyethylene plant is PetroChina’s first full-density polyethylene plant with “one head and two tails” double-line arrangement, and it is also the second full-density polyethylene plant with the largest production capacity in China. The device adopts UNIPOL process and single-reactor gas-phase fluidized bed process. It uses ethylene as the main raw material and can produce 15 kinds of LLDPE and HDPE polyethylene materials. Among them, the full-density polyethylene resin particles are made of polyethylene powder mixed with different types of additives, heated at a high temperature to reach a molten state, and under the action of a twin-screw extruder and a molten gear pump, they pass through a template and ar...
