Poly (Ethylene Carbonate) – QPAC® 25

Polyethylene carbonate, or QPAC®25, is a transparent, amorphous solid polymer that is easy to work with and has long-term mechanical stability. The formula for the compound is (C3H4O3)n.

The following forms are offered by QPAC®25:

  • Granulate
  • Solution


Ceramic, metal, or glass powders are used to create high-purity technical components, pastes, inks, and coatings. Barrier film in plastic production is an example of a non-binder application.

Key Benefits

  • Decomposition in a wide range of atmospheres, including air, oxygen, nitrogen, hydrogen, argon, and vacuum
  • Excellent clarity
  • Exceptional adhesion
  • Extrudable into barrier film for multi-layer construction
  • Low-temperature decomposition is excellent for thermally sensitive materials 
  • Outstanding green strength
  • Range of molecular weights from 50,000 to 200,000
  • Superb oxygen barrier properties
