QPAC®100 poly (propylene/cyclohexane carbonate)
QPAC®100 poly(propylene/cyclohexene carbonate) is an amorphous, clear, readily processable solid polymer with long-term mechanical stability.
What are the applications for QPAC®100?
Binder for ceramic, metal, or glass powders. Sacrificial structural applications include decomposable channel former and pore former.
QPAC®100 is available in the following forms:
- Pellet
- Solution
- Film
Key Benefits Include:
- Excellent adhesion and improved lubricity
- Co-firing in any atmosphere without oxidation
- Complete and clean burnout leaving less than 10 ppm ash residue, resulting in superb mechanical and/or electrical properties
- Outstanding green strength
- Low-temperature decomposition is excellent for thermally sensitive materials and is more efficient than other binders
- Products of combustion are only carbon dioxide & water
- Higher Tg (glass transition temperature) for more thermal stability at higher temperatures
- Designed for sacrificial placeholder applications
- Decomposition occurs in a wide range of atmospheres, including air, oxygen, nitrogen, hydrogen, argon, and vacuum
- Range of molecular weights from 150,000 to 200,000
