QPAC carbon dioxide polymer granules

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
