There are few mass-producers of PHBV in the world, Tianan Biotech is the largest supplier

Polyhydroxybutyrate-valerate copolyester (PHBV) is a new biopolymer copolymer of 3-hydroxybutyrate and 3-hydroxyvalerate. It is a biomaterial produced using starch as raw material and using fermentation engineering technology. PHBV is produced by bacterial fermentation and has the characteristics of complete biocompatibility, good optical activity, good heat resistance, and high barrier properties. It is widely used in medical materials, film materials, packaging materials, tableware, disposable supplies and other fields.

PHBV has excellent performance and a wide range of applications. However, its products have problems such as difficulty in processing, poor thermal stability, high crystallinity, hardness and brittleness. In practical applications, graft modification, copolymerization modification, and blending modification are often used. , compound modification and other modification technologies to improve the performance of PHBV and its products, such as PHBV and PCL blending, PHBV and PLA blending, PHBV and PBAT blending, etc.

Since the fermentation technology and extraction process are not yet mature, PHBV production costs are high, and PHBV applications are mostly concentrated in the field of consumer goods, which greatly limits its large-scale promotion and application. In this context, cheapness and high performance have become PHBV modification technologies important development direction. In the future, with the advancement of modification technology and stricter environmental protection policies, the application potential of PHBV will continue to be released.

my country is one of the countries in the world that can produce the largest variety of PHA products. It has the production capacity of the first-generation PHA product PHB, the second-generation PHA product PHBV, the third-generation PHA product PHBHHx and the fourth-generation PHA product P34HB. Among them, the main PHBV production companies are Ningbo Tianan Biomaterials Co., Ltd.

According to the “2023-2027 China Polyhydroxybutyric Valeric Acid Copolyester PHBV Market Feasibility Research Report released by the Industrial Research Center 》 shows that currently, there are few companies with PHBV mass production capabilities globally, and market competition is relatively relaxed. Tianan Biotech was established in 2000 and focuses on the production and application development of PHBV and PHB. It is currently the largest PHBV manufacturer.

PHBV has poor toughness and is suitable for injection molding, fiber and other applications. PHBV fiber is made by melt spinning after extracting PHBV. As a new type of fiber, PHBV fiber has the characteristics of antibacterial comfort, ecological environmental protection, and good human compatibility. It is suitable for knitted underwear, clothing, home textiles and other fields. With the concept of green, low-carbon, environmentally friendly and sustainable development deeply rooted in the hearts of the people, the PHBV fiber market has broad development prospects. At present, PHBV fiber-related companies include Wuxi Simian Textile Co., Ltd., Weiqiao Textile Co., Ltd., Nanjing Hesu Times Antibacterial Material Technology Co., Ltd., etc.

Industry analysts said that there are currently few PHBV mass-producers in the world and market competition is relatively relaxed. my country is in the leading position in PHBV production and research. Global leading level. Due to high production costs and poor product performance, the application of PHBV has been greatly restricted. However, with the deepening of research on modification technology and the increasing environmental protection requirements, the PHBV market still has huge development potential.
