Hainan Refinery’s million-ton ethylene and refining expansion project is about to be handed over.
The Hainan Refining and Chemical Ethylene Project and the Refining Reconstruction and Expansion Project are located in Yangpu Economic Development Zone, with a total investment of more than 28 billion yuan. Up to now, the overall construction progress has reached 98%. After the project is completed and put into production, it is expected to drive more than 100 billion yuan of downstream industries. Olefin Feedstock Diversification and High-end Downstream Forum will be held in Sanya on July 27-28. Under the new situation, the development of large-scale projects such as PDH, and ethane cracking, the future trend of new technologies such as direct crude oil to olefins, and new generation of coal/methanol to olefins will be discussed. -
MIT: Polylactic-glycolic acid copolymer microparticles make “self-enhancing” vaccine.
Scientists at the Massachusetts Institute of Technology (MIT) report in the recent journal Science Advances that they are developing a single-dose self-boosting vaccine. After the vaccine is injected into the human body, it can be released multiple times without the need for a booster shot. The new vaccine is expected to be used against diseases ranging from measles to Covid-19. It is reported that this new vaccine is made of poly(lactic-co-glycolic acid) (PLGA) particles. PLGA is a degradable functional polymer organic compound, which is non-toxic and has good biocompatibility. It has been approved for use in Implants, sutures, repair materials, etc. -
Yuneng Chemical Company: First industrialized production of sprayable polyethylene!
Recently, the LLDPE unit of the Polyolefin Center of Yuneng Chemical Company successfully produced DFDA-7042S, a sprayable polyethylene product. It is understood that the sprayable polyethylene product is a product derived from the rapid development of downstream processing technology. The special polyethylene material with spraying performance on the surface solves the problem of poor coloring performance of polyethylene and has high gloss. The product can be used in decoration and protection fields, suitable for children’s products, vehicle interiors, packaging materials, as well as large industrial and agricultural storage tanks, toys, road guardrails, etc., and the market prospect is very considerable. -
Petronas 1.65 million tons of polyolefin is about to return to the Asian market!
According to the latest news,Pengerang in Johor Bahru,Malaysia,has restarted its 350,000-ton/year linear low-density polyethylene (LLDPE) unit on July 4, but the unit may take a while to Achieve stable operation. Besides, its Spheripol technology 450,000 tons/year polypropylene (PP) plant, 400,000 tons/year high-density polyethylene (HDPE) plant and Spherizone technology 450,000 tons/year polypropylene (PP) plant are also expected to increase from this month to restart. According to Argus’ assessment, the price of LLDPE in Southeast Asia without tax on July 1 is US$1360-1380/ton CFR, and the price of PP wire drawing in Southeast Asia on July 1 is US$1270-1300/ton CFR without tax. -
Cigarettes switch to biodegradable plastic packaging in India.
India’s ban on 19 single-use plastics has prompted changes in its cigarette industry. Before July 1, Indian cigarette manufacturers had changed their previous conventional plastic packaging to biodegradable plastic packaging. The Tobacco Institute of India (TII) claims that their members have been converted and the biodegradable plastics used meet international standards, as well as the recently issued BIS standard. They also claim that the biodegradation of biodegradable plastics begins in contact with the soil and naturally biodegrades in composting without stressing solid waste collection and recycling systems. -
Brief Analysis of the Operation of Domestic Calcium Carbide Market in the First Half of the Year.
In the first half of 2022, the domestic calcium carbide market did not continue the wide fluctuation trend in 2021. The overall market was near the cost line, and it was subject to fluctuations and adjustments due to the impact of raw materials, supply and demand, and downstream conditions. In the first half of the year, there was no new expansion capacity of domestic calcium carbide method PVC plants, and the increase in calcium carbide market demand was limited. It is difficult for chlor-alkali enterprises that purchase calcium carbide to maintain a stable load for a long time. -
An explosion occurred in a PVC reactor of a petrochemical giant in the Middle East!
The Turkish petrochemical giant Petkim announced that on the evening of June 19, 2022, an explosion occurred at the Aliaga plant. the accident occurred in the factory’s PVC reactor, no one was injured, the fire was quickly under control, but the PVC unit may be temporarily offline due to the accident. The event may have a greater impact on the European PVC spot market. It is reported that because the price of PVC in China is much lower than that of Turkey’s domestic products, and the spot price of PVC in Europe is higher than that in Turkey, most of Petkim’s PVC products are currently exported to the European market. -
BASF develops PLA-coated oven trays !
On June 30, 2022, BASF and Australian food packaging manufacturer Confoil have teamed up to develop a certified compostable, dual-function oven-friendly paper food tray – DualPakECO®. The inside of the paper tray is coated with BASF’s ecovio® PS1606, a high-performance general-purpose bioplastic commercially produced by BASF. It is a renewable biodegradable plastic (70% content) blended with BASF’s ecoflex products and PLA, and is specially used for the production of coatings for paper or cardboard food packaging. They have good barrier properties to fats, liquids and odors and can save greenhouse gas emissions. -
Applying polylactic acid fibers to school uniforms.
Fengyuan Bio-Fiber has cooperated with Fujian Xintongxing to apply polylactic acid fiber to school wear fabrics. Its excellent moisture absorption and perspiration function is 8 times that of ordinary polyester fibers. PLA fiber has significantly better antibacterial properties than any other fibers. The curling resilience of the fiber reaches 95%, which is significantly better than any other chemical fiber. In addition, the fabric made of polylactic acid fiber is skin-friendly and moisture-proof, warm and breathable, and it can also inhibit bacteria and mites, and be flame retardant and fireproof. School uniforms made of this fabric are more environmentally friendly, safer and more comfortable. -
Nanning Airport: Clear out the non-degradable, please enter the degradable
Nanning Airport issued the “Nanning Airport Plastic Ban and Restriction Management Regulations” to promote the implementation of plastic pollution control within the airport. At present, all non-degradable plastic products have been replaced with degradable alternatives in supermarkets, restaurants, passenger rest areas, parking lots and other areas in the terminal building, and domestic passenger flights have stopped providing disposable non-degradable plastic straws, stirring sticks, packaging bags, use degradable products or alternatives. Realize the comprehensive “clearing out” of non-degradable plastic products, and “please come in” for environmentally friendly alternatives . -
What is PP resin ?
Polypropylene (PP) is a tough, rigid, and crystalline thermoplastic. It is made from propene (or propylene) monomer. This linear hydrocarbon resin is the lightest polymer among all commodity plastics. PP comes either as homopolymer or as copolymer and can be greatly boosted with additives. Polypropylene also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material and has a high chemical resistance.
