QPAC® poly(alkylene carbonate) copolymers are a unique family of thermoplastics representing a true breakthrough in polymer technology.

While traditional plastics have been primarily petroleum based, these new materials are derived from carbon dioxide and are produced through the copolymerization of CO2 with one or more epoxides.


Typical properties include:  Both QPAC®25 poly(ethylene carbonate) and QPAC®40 poly(propylene carbonate) burn in air with almost invisible flame, and their products of combustion are non-toxic (primarily carbon dioxide and water). In the absence of oxygen, thermal decomposition yields a cyclic carbonate which vaporizes for complete removal, leaving minimal ash residue. QPAC® poly(alkylene carbonate) copolymers are amorphous, clear, readily processable and have long-term mechanical stability. Additionally, QPAC®25 poly(ethylene carbonate) is enzyme degradable and biocompatible.
