5.11. Renewable Polycarbonate
5.11.1. Biosourced Polycarbonates
Thermoplastic bio-PCs can be made with isosorbide in place of BPA, in a process that avoids the use of phosgene. Mitsubishi Chemical has started production of Durabio bio-PC and Teijin proposes its Planext biopolycarbonate. Total capacity could be about 23,000 t/year.
Following information is claimed by Mitsubishi Chemical for its DURABIO™ bio-PC.
