Polybutylene succinate (PBS) has become the most promising biodegradable plastic with its excellent performance. Recently, PBS officially entered the “Eleventh Five-Year Plan” of the National Ministry of Science and Technology, becoming a fully biodegradable plastic that is promoting industrialization at the government level. It is reported that the Ministry of Science and Technology will start the "Eleventh Five-Year Plan" project for the industrialization of fully biodegradable plastics at the end of the year. At this point, PBS successfully won the industrialization initiative and became the leader in the industrialization of fully biodegradable plastics in China.
PBS is a leader in biodegradable plastic materials and has a wide range of uses. It can be used in packaging, tableware, cosmetic bottles and pharmaceutical bottles, disposable medical supplies, agricultural films, pesticides and chemical fertilizer sustained-release materials, and biomedical polymer materials. PBS has excellent comprehensive performance, reasonable cost performance and good application and promotion prospects.
Compared with other biodegradable plastics, PBS has excellent mechanical properties, close to PP and ABS plastics; good heat resistance, heat distortion temperature close to 100 °C, modified use temperature can exceed 100 °C, can be used to prepare hot and cold drinks packaging and The meal box overcomes the shortcomings of other biodegradable plastics that have low heat-resistant temperature; the processing performance is very good, and can be performed on various kinds of existing general-purpose plastic processing equipment. It is the best degradable plastic processing performance and can be blended at the same time. A large amount of calcium carbonate, starch and other fillers, to obtain low-cost products; PBS production can be slightly modified through the existing general-purpose polyester production equipment, the current domestic polyester equipment, a serious excess capacity, transform the production of PBS to provide excess polyester equipment New opportunities. In addition, PBS can only degrade under conditions of composting, water, and other exposure to specific microorganisms, and its performance is very stable during normal storage and use. PBS uses aliphatic dibasic acids and glycols as the main raw materials, which can meet the demand through petrochemical products, and can also be passed through bio-fermentation pathways of natural renewable crop products such as cellulose, dairy by-products, glucose, fructose, and lactose. Production, so as to realize the green cycle production from nature and return to nature. In addition, raw materials produced by the biological fermentation process can also significantly reduce the cost of raw materials, thereby further reducing the cost of PBS.
It is predicted that by 2010, the industry scale of degradable plastics in the world will reach about 10% of the total market share of plastic products. Therefore, as the most fully biodegradable plastic with industrial prospects, the industrial development prospect of PBS will be particularly broad.
