Bio-based PHA

Polyhydroxyalkanoates (PHA) are biodegradable polymers produced from renewable materials, mainly composed of ester bonds and hydroxyl functional groups. PHAs are naturally occurring polyesters in nature. They are formed by polymerization reactions of different monomers, and common monomers include hydroxy fatty acids. They are mainly composed of ester bonds and hydroxyl functional groups. They are formed by polymerization reactions of different monomers, and common monomers include hydroxy fatty acids, and have good biocompatibility and biodegradability. As a new type of degradable plastic, polyhydroxyalkanoates are in line with the trend of ecological and environmental protection and have broad application prospects.

The performance of PHA is mainly determined by the monomer structure and its content. Due to the variety of monomers, the main classifications include PHB, PHV, PHBV, etc. PHAs have different material properties according to their types and can be used in bioplastics, fibers, medical materials and other fields.
