HMW Polycarbonates


Poly(propylene carbonate) (PPC) is produced from propylene oxide (PO) and contains 43% CO2. PPC polycarbonates are transparent and have very low permeability to gas and liquids while being flexible.

Indeed, the barrier properties exceed those for conventional bio-derived polymers such as poly(lactic acid) (PLA). This makes PPC film useful for many packaging and lining applications, including for food and drink containers.


Poly(cyclohexene carbonate) or, in short, PCHC is produced from cyclohexene oxide (CHO) and CO2. It is a strong and stable material. PCHC contains 31% COand is targeted for the engineering plastics market.

Both polymers already have applications as sacrificial binders in the production of high value electronic components.
