Polyhydroxyalkanoates (PHA’s) are a family of 100% biobased (co-)polyesters that are produced through the bacterial fermentation of sugars and lipids. Because these polymers are produced by bacteria, they can also be broken down by bacteria, making them 100% soil AND marine biodegradable.
Especially this marine biodegradability makes it a unique group of biopolymers within the bioplastics market, as the problems of the Plastic soup and water-borne microplastics can’t be tackled by using other bioplastics, like PLA, PBS or PBAT.
PHA’s can be produced with a range of different monomers, by adjusting the feedstock and bacterial strains, resulting in a variety of co-polyesters with various properties.
Helian Polymers offers two of such types, a PHB (Polyhydroxybutyrate) and a PHBV (Poly(3-hydroxybutyrate-co-3-hydroxyvalerate). Both are highly crystalline thermoplastics that are produced by TianAn Biopolymer, using non-GMO bacteria and non-GMO feedstock. The difference between the two is that the PHBV contains a fraction of hydroxyvalerate in its polymeric backbone, making it a bit less crystalline and therefore a bit less brittle.
The PBHV can be acquired in both the granular form (ENMAT Y1000P) or in powdered form (ENMAT Y1000).
Within the ENMAT Y1000P a nucleating agent is also incorporated.
The PHB we have on stock in the the granular form (ENMAT Y3000P), but can also be ordered in powdered form on special request.
Within the ENMAT Y3000P a nucleating agent is incorporated as well.
