Polyhydroxyalkanoates

 Polyhydroxyalkanoates




  • Polyhydroxyalkanoates or PHAs are linear polyesters produced in nature by bacterial fermentationof sugar or lipids. 
  • PHA are produced by the bacteria to store carbon and energy. 
  • PHA plastics are biodegradeable and are used in the production of bioplastics.
  • Polyhydroxyalkanoastes (PHAs) are naturally-occurring polymers produced by bacteria. 
  • PHA are for use in many applications, including molded goods, paper coatings, non-woven fabrics, performance additives.
  • A PHA copolymer called PHBV is less stiff and tougher, and it may be used as packaging material.
