Poly (Propylene Carbonate) – QPAC® 40
Polypropylene carbonate, or QPAC®40, is a transparent, amorphous solid polymer that is easy to work with and has long-term mechanical stability. The formula for the compound is (C4H6O3)n.
QPAC®40 comes in the following configurations:
- Pellet
- Solution
- Film
- Aqueous Dispersion/Emulsion
Applications
QPAC®40 polypropylene carbonate is used as a binder to create high-purity technical components, pastes, inks, and coatings when combined with ceramic, metal, or glass powder. Applications for sacrificial structures include pore and decomposable channel formers. Barrier film is one non-binder application in plastic processing.
Key Benefits:
- Complete and clean burnout leaving less than 10 ppm ash residue, resulting in superb mechanical and/or electrical properties
- Decomposition occurs in a wide range of atmospheres, including air, oxygen, nitrogen, hydrogen, argon, and vacuum
- Excellent viscosity properties in ink/paste systems
- Low-temperature decomposition is excellent for thermally sensitive materials and is more efficient than other binders
- Outstanding green strength
- Great adhesion and improved lubricity
- Products of combustion are only carbon dioxide & water
- Range of molecular weights from 100,000 to 300,000
