Product overview
PHA (Polyhydroxyalkanoates) is a polymer biomaterial found in microbial cells such as bacterial cells (similar to bacterial fat).PHA is not only the product of bacteria when the growth conditions are unbalanced, but also the carbon source and energy storage substance in microorganisms.PHA is a polymer consisting of 100-3000 identical or different hydroxyl fatty acid monomers, most of which are 3-hydroxyl fatty acids with chain lengths of 3-14 carbon atoms, and side chains are highly variable aromatic or aliphatic groups.
The latest research shows that there are more than 150 kinds of PHA monomers, which constitute a huge polymer family.The rich and varied material properties and environmentally friendly degradability make it one of the polymers that replace traditional petrochemical plastic products.
At present, a total of four types of PHA have been industrialization, including polyhydroxybutyrate (PHB), 3-hydroxybutyrate 3-hydroxyvalerate copolyester (PHBV), 3-hydroxybutyrate 3-hydroxycaproate copolyester (PHBHHx) and 3-hydroxybutyrate 4-hydroxybutyrate copolyester (P34HB), etc., which have their own advantages in practical applications.
PHA product performance can also be compared with other degradable materials
