High Impact-High Stiffness Bacterial Bioplastic
Description of Technology
This technology is a new approach for producing biodegradable plastic that overcomes some prior limitation inherent in the use of Polyhydroxybutyrate (PHB). PHB is a desirable material because of its high crytallinity and water resistance. Crytallinity is when chains pack closely together in a regular way, allowing stronger intermolecular forces. The polymer is less flexible and stronger as a result. The current technology addresses the inflexibility (brittleness) and thermal instability of PHB through the incorporation of high modulus fillers (clay).
- Improved flexibility: Toughness and impact strength of PHB are improved, without compromising its inherent stiffness and strength.
- Low cost: The toughened polymer composition is relatively inexpensive and easy to manufacture.
The primary target market for the technology is the replacement of toughened polyolefins automobile parts and similar structural applications.
