Polypropylene carbonate (PPC) is a new degradable plastic and its production capacity is expanding rapidly

Polypropylene carbonate, also known as polymethylethylene carbonate, abbreviated as PPC in English, is an important carbon dioxide copolymer. It is a resin made from carbon dioxide and propylene oxide as raw materials, adding a catalyst, and undergoing a polymerization reaction. Material. The appearance of polypropylene carbonate is transparent or white or light yellow solid or semi-solid. It is insoluble in water, alcohol and ether, and soluble in benzene, acetone and chloroform.

According to the “Polypropylene Carbonate (PPC) Industry In-depth Market Research and Investment Strategy Suggestions Report 2022-2026” released by the Industrial Research Center shows that polypropylene carbonate has excellent toughness, impact resistance, water resistance, oxygen resistance, biocompatibility, non-toxicity and biodegradability, and can be used to make food plastic wrap, food packaging, disposable Tableware, disposable medical equipment, foam plastics, sheets, agricultural films and other products are widely used in food and beverage, catering, medical, agriculture and other fields. In addition, polypropylene carbonate can also be blended with other polymers such as polyethylene, polypropylene, and polycarbonate to improve the product’s water barrier, oxygen barrier and other properties.

Polypropylene carbonate has a low glass transition temperature and is generally used to manufacture products used under low temperature conditions, which limits the expansion of its application scenarios. In recent years, the preparation technology of polypropylene carbonate has continued to improve, and the glass transition temperature has been increased. In addition, research on the modification of polypropylene carbonate is also in-depth. For example, using carbon dioxide, propylene oxide, and phthalic anhydride as raw materials, adding catalysts for polymerization to produce PPCP can also increase the glass transition temperature of the product. This will help expand the application range of polypropylene carbonate.

Global carbon dioxide emissions continue to increase. According to data from the International Energy Agency, global carbon dioxide emissions will reach 36.3 billion tons in 2021, a year-on-year increase of 6%; China’s carbon dioxide emissions will reach 11.9 billion tons, accounting for 33%. In order to achieve “carbon peak” and “carbon neutrality”, in addition to reducing carbon dioxide emissions, consuming carbon dioxide in the atmosphere is also an important means. The development of polypropylene carbonate can consume carbon dioxide in the atmosphere, thereby slowing down the greenhouse effect. At the same time, polypropylene carbonate is a biodegradable resin, so its environmental protection advantages are outstanding.

The main polypropylene carbonate-related research institutes in my country include the Chinese Academy of Sciences, Sun Yat-sen University, etc.; the main polypropylene carbonate manufacturers in my country include Inner Mongolia Mengxi High-tech Group Co., Ltd., Taizhou Bangfeng Plastic Co., Ltd., and Henan Tianguan Enterprise Group Co., Ltd. , Jiangsu Zhongke Jinlong Chemical Co., Ltd., etc. In the early days, due to limitations of application scenarios, the production and sales scale of polypropylene carbonate in my country was limited. Currently, with the continuous advancement of its production technology, the scale of the industry is still expanding.

Industry analysts said that during the “14th Five-Year Plan” period, my country’s including Jilin Boda Dongfang New Materials Co., Ltd., Maoming Tianyuan Petrochemical Co., Ltd. Many companies, including the company and Sinochem Quanzhou Petrochemical Co., Ltd., plan to build polypropylene carbonate production capacity. It is expected that by the end of the “14th Five-Year Plan”, my country’s polypropylene carbonate production capacity will reach 650,000-700,000 tons. At this stage, in my country’s degradable plastic market, polypropylene carbonate accounts for a small share. In the future, as production capacity and output increase, its penetration rate will continue to increase, and the market size will continue to expand.
