PHA for General Purpose

At Alfa Chemistry, we provide a wide range of PHA products, including PHA materials for general urpose and specialized applications. In the general purpose PHA series, we use glucose as the raw material and produce two high-quality PHA materials: PHB (Poly(3-Hydroxybutyric acid)) and PHBV (Poly(3-Hydroxybutyric acid-co-3-hydroxyvaleric acid)) powders and pellets, through microbial fermentation. These materials serve as sustainable alternatives to petroleum-based plastics and have diverse applications.
