050009: High Impact-High Stiffness Bacterial Bioplastic
Case ID:
TEC2005-0009
Web Published:
7/21/2014
Description:
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).
Benefits
* 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.
Applications
The primary target market for the
technology is the replacement of toughened polyolefins automobile parts and
similar structural applications.
