PBS fully biodegradable plastic has broad prospects

polybutylene succinate (PBS) has become the most industrialized fully biodegradable plastic because of its excellent performance. Recently, PBS was officially shortlisted in the "Eleventh Five Year Plan" of the Ministry of science and technology, and became a fully biodegradable plastic promoted by the government. It is reported that the Ministry of science and technology of the people's Republic of China will launch the "Eleventh Five Year Plan" project for the industrialization of fully biodegradable plastics in advance at the end of the year. So far, PBS has successfully won the industrialization opportunity and become the leader in the industrialization of fully biodegradable plastics in China

pbs is a leader in biodegradable plastic materials. It is widely used in packaging, tableware, cosmetic bottles and drug bottles, disposable medical supplies, agricultural film, pesticide and fertilizer slow-release materials, biomedical polymer materials and other fields. PBS has excellent comprehensive performance and reasonable cost performance, and has a good application and promotion prospect

compared with other biodegradable plastics, PBS has excellent mechanical properties, close to PP and ABS plastics; It has good heat resistance, the thermal deformation temperature is close to 100 ℃, and the use temperature after modification can exceed 100 ℃, which can be used to prepare cold and hot drink packaging and lunch boxes, overcoming the shortcomings of other biodegradable plastics with low heat resistance temperature; The processing performance is very good. It can carry out all kinds of USB data storage and connection processing on the existing general plastic processing equipment. It is currently degraded. If the above problems are not found, the plastic processing performance is the best. At the same time, it can be blended with a large number of calcium carbonate, starch and other fillers to obtain low-cost products; PBS production can be carried out by slightly reforming the existing general polyester production equipment. At present, the domestic polyester equipment has a serious overcapacity. The transformation and production of PBS provides a new opportunity for the excess polyester equipment to clamp the sample symmetrically according to the requirements. In addition, PBS is degraded only when it is exposed to specific microorganisms such as compost and water, and its performance is very stable during normal storage and use. PBS takes aliphatic dicarboxylic acid and diol as the main raw materials, which can not only meet the demand through petrochemical products, but also be produced through biological fermentation of natural renewable crop products such as cellulose, dairy by-products, glucose, fructose, lactose, etc. with low sampling rate, it can realize the green circular production from nature and return to nature. Moreover, the raw materials produced by 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 industrial scale of degradable plastics in the world will reach about 10% of the market share of the whole plastic products. Therefore, as a fully biodegradable plastic with the most industrialization prospect, the industrial development prospect of PBS will be particularly broad
