Pure polyhydroxyalkanoate (PHA) biopolymer

Model Number: EM5400F Brand Name: AmBio Key Specifications/Special Features: Innovation:EcomannPHA (polyhydroxyalkanoates) biopolymersare liner polyester produced in nature by bacterial fermentation of sugar or lipidsThey are produce by the bacteria to carbon and energyMore than 150 different monomers can be combined within this family to give materials with extremely different propertiesAfter the bacteria have made the resin they are washed out leaving a power that can be processed either directly into plastic products or shaped into pellets for further processingThey can be either thermoplastic or elastomeric materials, with melting points ranging from 41 to 180 Celsius
The mechanical and biocompatibility of PHA can also be changed by blending, modifying the surface or combining PHA with other polymers, enzymes and inorganic materials, making it possible for a wide range of applications
