The continuous development of modification technology will help unleash the development potential of the PHBV industry

The sustainable development of modification technology promotes the release of the development potential of the PHBV industry

Polyhydroxybutyric valerate copolyester (PHBV) is a natural polymer polyester extracted from living organisms. It is also a copolymer of new biopolymers 3-hydroxybutyrate and 3-hydroxyvalerate. It can be made from starch as raw material and using fermentation engineering technology. PHBV has the characteristics of complete biocompatibility, high barrier to water and gas, and good optical activity. It is widely used in medical materials (sutures, bone nails), film materials, disposable products, packaging materials and other fields. prospect.

However, in the actual development process, PHBV has shortcomings such as poor thermal stability, high crystallinity, poor toughness, brittleness, and easy degradation during processing. It has many limitations when used alone and has high production costs. In addition, the maturity of PHBV fermentation and extraction processes It is still not high, mass production capacity is limited, and the current global PHBV market size is still relatively small.

According to the “2021-2025 China Polyhydroxybutyrate Valerate Copolyester PHBV Market Feasibility Research Report” released by the Industrial Research Center It shows that in recent years, with the deepening of research on PHBV in various fields of industry, academia and research, modified PHBV has gradually developed. Physically mixing PHBV with other substances through blending and compounding to achieve PHBV modification is currently a more commonly used PHBV modification method, such as blending of PHBV and PCL, blending of PHBV and PBAT, blending of PHBV and PLA, and blending of PHBV and Starch, fiber blending, etc.

From the perspective of industry competition, there are extremely limited companies with PHBV mass production capabilities globally. At present, the only company that has realized the industrial production of second-generation bioplastic PHBV is Ningbo Tianan Biomaterials Co., Ltd. The number of companies is small and competition is relatively relaxed. As for Ningbo Tianan Biomaterials Co., Ltd., the company is an expert in the research, development and production of biopolymers, focusing on the production and application development of polyhydroxybutyrate-valerate (PHBV), and is one of the largest PHBV manufacturers.

From the perspective of the application of PHBV, Wuxi Simian Textile Co., Ltd. and Nanjing Hesu Times Antibacterial Material Technology Co., Ltd. have used PHBV to spin antibacterial yarns, and Ningbo Hesu Fiber Co., Ltd. has used PHBV to produce blends through melt spinning. Such as filament and short fiber. In addition, PHBV has not yet achieved large-scale applications in medical sutures, agricultural mulch films, shopping bags, tableware, and food packaging materials. In the future, with the continuous advancement of PHBV modification process technology, the improvement of PHBV mass production capabilities, and the advancement of environmental protection policies, the application potential of PHBV will be gradually released.

Industrial analysts said that my country is currently at the forefront of the world in research and industrial production in the field of PHBV, but due to the performance of PHBV itself Defects and high production costs have severely restricted its development. In the future, as the application and integration of modification technology deepens in the PHBV industry, the performance of PHBV blends will be significantly improved. At the same time, with the innovation of PHBV blend fillers, the production cost of PHBV is expected to be reduced, which will help promote the expansion of the PHBV market size. .
