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%. From the above chart, we can see that the export volume from January to February has increased significantly compared with the same period in 2022. In terms of months, the export volume in January 2023 increased by 16,600 tons compared with the same period last year, and the export volume in February increased by 40,900 tons compared with the same period last year; in terms of varieties, the export volume of LDPE (January-February) was 36,400 tons , a ye... -
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... -
Chemdo plans to participate in exhibitions this year.
Chemdo plans to participate in domestic and foreign exhibitions this year. On February 16, two product managers were invited to attend a course organized by Made in China. The theme of the course is a new way of combining offline promotion and online promotion of foreign trade enterprises. The course content involves the preparation work before the exhibition, the key points of negotiation during the exhibition and the customer follow-up after the exhibition. We hope that the two managers will gain a lot and promote the smooth progress of the follow-up exhibition work. -

How to avoid being cheated when buying Chinese products especially PVC products .
We have to admit that the international business is full of risks, filled in much more challenges when a buyer is choosing his supplier. We also admit that the fraud cases actually happen everywhere including in China. I have been an international salesman for nearly 13 years, meeting lots of complaints from various customers who were cheated one time or several times by Chinese supplier, the cheating ways is quite “funny”, such as getting money without shipping, or delivering low quality product or even delivering quite different product. As a supplier myself, I totally understand how the feeling is if somebody has lost huge payment especially when his business just starts or he is a green entrepreneur, the lost must be huge striking to him, and we have to admit that to get...
