==Properties== *Water-insoluble and relatively resistant to hydrolytic degradation. This differentiates PHB from most other currently available [[biodegradable plastic]]s, which are either water-soluble or moisture-sensitive. *Good oxygen permeability. *Good ultra-violet resistance but poor resistance to acids and bases. *Soluble in chloroform and other chlorinated hydrocarbons.<ref>{{cite journal |id={{INIST|19110437}} |doi=10.1002/aic.11274 |title=Solubility of polyhydroxyalkanoates by experiment and thermodynamic correlations |journal=AIChE Journal |volume=53 |issue=10 |pages=2704β14 |year=2007 |last1=Jacquel |first1=Nicolas |last2=Lo |first2=Chi-Wei |last3=Wu |first3=Ho-Shing |last4=Wei |first4=Yu-Hong |last5=Wang |first5=Shaw S. |doi-access=free |bibcode=2007AIChE..53.2704J }}</ref> *Biocompatible and hence is suitable for medical applications. *Melting point 175 Β°C., and glass transition temperature 2 Β°C. *Tensile strength 40 [[Pascal (unit)|MPa]], close to that of polypropylene. *Sinks in water (while polypropylene floats), facilitating its anaerobic biodegradation in sediments. *Non-toxic. *Less 'sticky' when melted.
