In 2022, the crude oil price is high. Andulan explained that the supply of the oil market in the first half of last year was "almost not growing", while the demand was recovering. At the same time, after the escalation of the Russian-Uzbekistan conflict in February, the market appeared to be worried about the supply of Russian crude oil. even if the macroeconomic background is weak in 2023, the demand for oil may still rise by about 4% at some time in the year.

According to the data analytics company-Globaldata, as time going by, Asia will improve ethylene capacity through building new programs and expand programs from 2022 to 2030 within 30 years, until 2030, Asian will account 60% market share in the world market.

Epoxy resin has excellent heat resistance, electrical insulation, adhesion, dielectric property, mechanical property, small shrinkage, chemical resistance, and good processability and operability after adding curing agent. Therefore, at present, foreign semiconductor devices are mostly encapsulated with epoxy resin.

In 2022, PVC industry adjusted at the beginning and end of the year, with a sharp drop in the middle of the year.

Since the 1970s, with the price rise of traditional energy and the impact of global climate change, Worldwide countries gradually realize the importance of biofuels. It is estimated that the carbon dioxide emission of biofuels is 50% of that of fossil fuels. It is estimated that the carbon dioxide emission of biofuels is 50% of that of fossil fuels. biofuels will be one of the key growth engines of the company's energy transformation.

There are about a dozen kinds of medical plastic materials that commonly used in medical field, Polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyurethane (PU), polytetrafluoroethylene (PTFE), polycarbonate (PC), polystyrene (PS), etc., with the largest amounts of PVC and PE, accounting for 28% and 24% respectively; PS accounts for 18%; PP accounts for 16%; Engineering plastics accounted for 14%.

Resin chemicals are widely used in potting and packaging in the electronic and electrical industries, but the right choice can not be made at the beginning. Since there are so many resins to choose from, it is a challenge to decide which resin is most suitable for your application. This paper focuses on the characteristics and applications of different types of resins.

PVC resin is the second largest raw material in the world, and there are many kinds of PVC resin on the market. Today, let's introduce the SG series. SG represents the PVC resin produced by suspension method, which is generally divided into 1~8 types, that is, SG1~SG8, SG1 has the largest molecular weight, and SG8 has the smallest molecular weight.

The density of pure titanium at room temperature (25 ℃) is 4.505g/cm3. melting point of titanium is (1668 ± 5) ℃. boiling point of titanium is (3260 ± 20) ℃. the specific heat capacity of titanium at 20 ℃ is 500J/(kg · K).

There are many production processes of PVC. According to the different monomer vinyl chloride, the production processes are mainly divided into calcium carbide method and ethylene method.PVC by calcium carbide method is a coal chemical route. Ethylene method PVC is a petrochemical route.

Differences in PVC production technology. There are two production processes of PVC, one is chlorination process, the other is acetylene process.

According to Vietnam's 《Business report》, in the first 11 months of 2022, the exportation of Vietnam rubber is around 1.86 million tons, value 2.93 billion US dollars, increased 9.1% and 3% year on year respectively.

Polypropylene (PP), as one of the five general plastics in China, is widely used. Plastic woven bags, films on the outside of packaging materials, masks, non-woven protective clothing, wave buckets inside washing machines, and car bumpers are all made of polypropylene. It is understood that at the beginning of 2022, the planned new capacity of the industry statistics is about 7.35 million tons. Up to now, 2.8 million tons have been put into production in the first half of the year and 1.8 million tons in the second half of the year.

The capacity utilization rate of PVC manufacturers increased by 0.88% month on month to 71.16%, a year-on-year decrease of 4.32%; Among them, calcium carbide PVC increased by 0.67% month on month to 68.59%, down 10.39% year on year; ethylene PVC increased by 1.64% month on month to 80.10%, up 16.58% year on year; The total output of PVC was 393600 tons, up 1.33% month on month and down 4.96% year on year.

IEA d on the consumption data, predict that the demand for oil will increase globally this and next year. OPEC said that the growth of global oil demand is expected to remain unchanged, with a daily increase of 2.5 million barrels this year and 2.2 million barrels next year. However, OPEC warned: "As approaching the end of 2022, the recent slowdown in global economic growth and its far-reaching impact are becoming quite obvious. It is expected that there will still have many uncertainties in 2023, which requires vigilance and caution."
