Applications

QPAC® poly(alkylene carbonate) polymers can be processed using typical thermoplastic processing techniques, including solution processing, spin casting, injection molding or extrusion. These materials have an exciting blend of unique properties that translate into superior performance for advanced ceramics processed by pressing or tape casting operations, sealing glasses, thick film paste systems, powdered metals, composites, and MEMS structures.

Key benefits:

Virtually No Residue / No contamination < 10 ppm residue ash and metal
Low Temperature Clean Burnout Onset at 220°C complete at 350°C or lower
All Sintering Atmospheres Nitrogen, Oxygen, Argon, hydrogen, Vacuum (oxygen generated in debind)
Benign Emissions Water and CO2
Excellent Green Strength Tacky, High Molecular Weight, amorphous, thermoplastic, polymer, allows high density green shaped, tapes, films, and other structures. The low Tg also provides good flexibility and adhesion.
Controlled Debind Polymer chain unzipping means controlled migration of debind emissions through part. Also results in excellent pore size management.

Thermogravimetric analyses in both air and nitrogen show complete decomposition of QPAC®40 poly(propylene carbonate) at low temperatures, heating rate is 10°C/minute.
