PHAs: Poly(hydroxyalkanoates)

PHAs: Poly(hydroxyalkanoates)

If you have a PHA need, please complete this form with information on your volume, location and lead time requirements, and your target application. 

 

PHAs general characteristics include water insolubility, relative resistance to hydrolytic degradation, biocompatibility and suitability for medical applications, as well as nontoxicity. Although PHAs are not water soluble, they are still degradable and biocompatible. In addition, PHAs are considered less sticky than other polymers once heated, and they sink in water which facilitates their anaerobic biodegradation in sediments.
