Cross-linked polyhydroxyalkanoate polymeric materials

Cross-linked polyhydroxyalkanoate (PHA) bioplastics unlock tougher, processable biopolymer parts without licensing roadblocks.

What it is

Cross-linked polyhydroxyalkanoate polymers form a bioplastic network by chemically linking polymer chains, improving stiffness and durability while keeping melt/processability for shaping. Cross-linking can materially raise mechanical performance compared with uncross-linked PHA while still enabling industrial processing like extrusion or molding. Previously, commercial use of these specific cross-linked PHA material formulations and methods required rights from the patent holder.

What you could build

Develop injection-molded or extruded rigid bioplastic housings and consumer packaging using cross-linked PHA blends.
