Siemens develops a biobased alternative to ABS plastic

摘要

Researchers at Siemens have developed an alternative to standard polystyrene-based acrylonitrite-butadi-ene-styrene (ABS) polymer made from biobased polyme and carbon dioxide. The new material is the result of a three-year project on funded by the German Research Ministry in cooperation with project partners from BASF, Munich Technical University, and the University of Hamburg. The new composite material is a mixture containing polyhydroxybutyrate (PHB), which is made from renewable raw materials such as palm oil and starch. Since PHB is brittle, polypropylene carbonate (PPC) from BASF is added to make it softer.
