What is HDPE ?
HDPE is defined by a density of greater or equal to 0.941 g/cm3. HDPE has a low degree of branching and thus stronger intermolecular forces and tensile strength. HDPE can be produced by chromium/silica catalysts, Ziegler-Natta catalysts or metallocene catalysts. The lack of branching is ensured by an appropriate choice of catalyst (e.g. chromium catalysts or Ziegler-Natta catalysts) and reaction conditions. HDPE is used in products and packaging such as milk jugs, detergent bottles, margarine tubs, garbage containers and water pipes. HDPE is also widely used in the production of fireworks. In tubes of varying length (depending on the size of the ordnance), HDPE is used as a replacement for the supplied cardboard mortar tubes for two primary reasons. One, it is much safer than the suppli... -
The spot price of PVC is stable, and the futures price rises slightly .
On Tuesday, PVC fluctuated within a narrow range. Last Friday, the US non-farm payrolls data was better than expected, and the Fed’s aggressive interest rate hike expectations were weakened. At the same time, a sharp rebound in oil prices also supported PVC prices. From the perspective of PVC’s own fundamentals, due to the relatively concentrated maintenance of PVC installations recently, the industry’s operating load rate has dropped to a low level, but it has also overdrafted some of the benefits brought by the market outlook. Gradually increasing, but there is still no obvious improvement in downstream construction, and the resurgence of the epidemic in some areas has also disrupted downstream demand. The rebound in supply may offset the effect of the small increase... -
Demonstration of Biodegradable Plastic Film in Inner Mongolia ！
After more than a year of implementation, the “Inner Mongolia Pilot Demonstration of Water Seepage Plastic Film Dry Farming Technology” project undertaken by Inner Mongolia Agricultural University has achieved phased results. At present, a number of scientific research achievements have been transformed and applied in some alliance cities in the region. Seepage mulch dry farming technology is a technology that is mainly used in semi-arid areas in my country to solve the problem of white pollution in farmland, efficiently utilize natural precipitation resources, and improve crop yields in dry land. Significantly. In 2021, the Rural Department of the Ministry of Science and Technology will expand the pilot demonstration area to 8 provinces and autonomous regions including Hebe... -
U.S. interest rate hike heats up, PVC surges and falls .
PVC closed down slightly on Monday, after Federal Reserve Chairman Powell warned against prematurely loosening policy, the market is expected to raise interest rates again, and production is expected to gradually resume as the hot weather is lifted. Recently, under the influence of the epidemic situation and power shortage in some areas, the production of PVC plants has been stopped and reduced. On August 29, the Sichuan Energy Emergency Office lowered the emergency response to energy supply guarantee for emergencies. Previously, the National Meteorological Administration also expected that the temperature in some high-temperature areas in the south would gradually drop from the 24th to the 26th. Some of the production cuts brought about may be unsustainable, and the high temperature po... -

The production capacity of PE continues to increase, and the structure of import and export varieties changes.
In August 2022, the HDPE plant of Lianyungang Petrochemical Phase II was put into operation. As of August 2022, China’s PE production capacity increased by 1.75 million tons during the year. However, considering the long-term production of EVA by Jiangsu Sierbang and the extension of the second phase of LDPE/EVA plant, its 600,000 tons / The annual production capacity is temporarily stripped from PE production capacity. As of August 2022, China’s PE production capacity is 28.41 million tons. From the perspective of comprehensive production, HDPE products are still the main products for capacity expansion during the year. With the continuous increase of HDPE production capacity, the competition in the domestic HDPE market has intensified, and the structural surplus has gradua... -
International sports brand launches biodegradable sneakers.
Recently, sporting goods company PUMA began distributing 500 pairs of experimental RE:SUEDE sneakers to participants in Germany to test their biodegradability. Using the latest technology, the RE:SUEDE sneakers will be made from more sustainable materials such as tanned suede with Zeology technology, biodegradable thermoplastic elastomer (TPE) and hemp fibers. During the six-month period when participants wore RE:SUEDE, products using biodegradable materials were tested for real-life durability before being returned to Puma through a recycling infrastructure designed to allow the product Proceed to the next step of the experiment. The sneakers will then undergo industrial biodegradation in a controlled environment at Valor Compostering B.V., which is part of Ortessa Groep B.V., a Dutch ... -
A brief analysis of China‘s import and export data of paste resin from January to July.
According to the latest statistics from the Customs, in July 2022, the import volume of paste resin in my country was 4,800 tons, a month-on-month decrease of 18.69% and a year-on-year decrease of 9.16%. The export volume was 14,100 tons, a month-on-month increase of 40.34% and a year-on-year increase An increase of 78.33% last year. With the continuous downward adjustment of the domestic paste resin market, the advantages of the export market have emerged. For three consecutive months, the monthly export volume has remained above 10,000 tons. According to the orders received by manufacturers and traders, it is expected that the domestic paste resin export will remain at relatively high level. From January to July 2022, my country imported a total of 42,300 tons of paste resin, down ... -
What is PVC ?
PVC is short for polyvinyl chloride, and its appearance is white powder. PVC is one of the five general plastics in the world. It is widely used globally, especially in the construction field. There are many types of PVC. According to the source of raw materials, it can be divided into calcium carbide method and ethylene method. The raw materials of calcium carbide method mainly come from coal and salt. Raw materials for ethylene process mainly come from crude oil. According to different production processes, it can be divided into suspension method and emulsion method. The PVC used in the construction field is basically suspension method, and the PVC used in the leather field is basically emulsion method. Suspension PVC are mainly used to produce: PVC pipes, P... -
Boosted by interest rate cuts, PVC repairs low valuation rebound ！
The PVC rebounded higher on Monday, and the central bank’s reduction of LPR interest rates is conducive to reducing the interest rate of residents’ home purchase loans and the medium and long-term financing costs of enterprises, boosting confidence in the real estate market. Recently, due to the intensive maintenance and the continuous large-scale high temperature weather across the country, many provinces and cities have introduced power curtailment policies for high-energy-consuming enterprises, resulting in a phased contraction of the PVC supply margin, but the demand side is also weak. From the perspective of downstream performance, the current situation The improvement is not great. Although it is about to enter the peak demand season, the domestic demand is rising slow... -
Expansion! Expansion! Expansion! Polypropylene (PP) all the way forward!
In the past 10 years, polypropylene has been expanding its capacity, of which 3.05 million tons was expanded in 2016, breaking the 20 million tons mark, and the total production capacity reached 20.56 million tons. In 2021, the capacity will be expanded by 3.05 million tons, and the total production capacity will reach 31.57 million tons. The expansion will be concentrated in 2022. Jinlianchuang expects to expand the capacity to 7.45 million tons in 2022. In the first half of the year, 1.9 million tons have been put into operation smoothly.
