Development background of the polyvinyl chloride pvc polypropylene
With the rapid development of the polyvinyl chloride pvc, household appliances, logistics industry, electronic telecommunications industry, etc., combined with the development trend of new polypropylene products of multinational petrochemical companies in recent years, the market of "three high and two low" polypropylene will be larger and larger.
In the traditional sense, high crystalline polypropylene refers to polypropylene resin with high crystallinity, high crystallization temperature, high stiffness, and high heat resistance prepared by adding an efficient nucleating agent on the basis of the high structure and regularity of the polyvinyl chloride pvc. It is widely used in electrical components, home furnishing, and other occasions, and belongs to high-end products of polypropylene.
In recent years, major polyolefin companies, such as SK and LyondellBasell, are developing high crystal impact polypropylene technology. The BX3900, BX3920, 540V, and other products sold by them are widely recognized by users as soon as they hit the market, and their prices are more than 1000 yuan/ton higher than ordinary impact polypropylene. It can be predicted that high crystal impact polypropylene will replace existing high crystal polypropylene and impact polypropylene to a large extent, and become the leading brand of the polyvinyl chloride pvc in the future.
Will the price of the polyvinyl chloride pvc rise as Russia and Ukraine fight?
The fire, to Ukraine in the short term lead to the international crude oil, the natural gas market rose sharply, is a positive impact on the domestic refining production: in the high-end transformation of the polyvinyl chloride pvc, nylon, and other materials industry in China, prior to the completion of oil chemical raw materials rose sharply and domestic high-end brand capacity is limited, is bound to cause some refining and downstream device starts falling. Downstream end-consumer manufacturers are cautious about stockpiling after raw material price volatility in 2021.
China began to study the process of polypropylene production in 1962. Since the 1980s, polypropylene has developed rapidly in China. In recent years, most new large refining, ethylene cogeneration, and coal olefin projects have been equipped with polypropylene units, so China's polypropylene capacity will increase significantly in the future.

Market and application of "three high" the polyvinyl chloride pvc
At present, the demand for HCPP in China is 250,000-300,000 tons per year, and the growth rate is 10-15% per year, indicating a broad market prospect.
China's HCPP demand is dominated by imported products, accounting for about 70% of the total demand. There are SK, Hanwha Total, Daehan Oil chemical, LyondellBasell, Exxon, and so on. SK of South Korea alone exports about 60,000-80,000 tons of HCPP to the Chinese market every year, and its price is 2000-3000 yuan/ton higher than that of ordinary impact-resistant PP.
HCPP is mainly used in automobile parts, such as column, door panel, bumper, etc., home appliance modified products, large injection products, etc. With the development of China's automotive industry and the trend of lightweight vehicles, the demand for HCPP is increasing.
In recent years, with the development of the polyvinyl chloride pvc and technology, plastic products are increasingly large thin, lightweight, comfortable direction, some of the large automotive spare parts, using polypropylene injection molding can reduce body weight, this not only reduces the fuel consumption, and reduced emissions of carbon dioxide, to protect the environment is of great significance. At present, the proportion of the polyvinyl chloride pvc used in vehicles has reached more than 50%.
The demand for modified plastic materials in China's automotive sector has risen from 3.52 million tons in 2015 to 4.66 million tons in 2019. With the steady improvement of automobile production and sales and the development of automobiles to lightweight, it is expected that the demand for modified materials in the automobile field will maintain good upward momentum. The annual demand for high fluidity, high crystallization, and high impact polypropylene injection plastics in China is about 150-250,000 tons, and the annual growth rate is more than 10%. Lightweight, low cost, high mobility such materials have good processing performance, the short production cycle of finished products, while high crystallinity can improve the rigidity of materials, reduce the thickness of finished products, reduce the quality of materials. In addition, the high content of ethylene-propylene rubber can increase the strength of the finished product. The research shows that: in terms of fuel consumption, every 10% decrease in vehicle quality, fuel consumption will decrease by 6-8% and emissions will decrease by 4%; In terms of power economy, the power performance of 0-100km /h acceleration increases by 7% for every 100kg weight loss; In terms of the polyvinyl chloride pvc braking performance, for every 100kg weight loss, the braking distance is shortened by 2-7m at low speed and 1-2m at high speed for every 100kg weight loss. In terms of electric vehicle range, the range of electric vehicles increases 15-20km for every 100kg weight loss.
