QPAC®25 poly(ethylene carbonate)

QPAC®25 poly(ethylene carbonate) is an amorphous, clear, readily processable solid polymer with long-term mechanical stability. The chemical formula is (C3H4O3)n.

QPAC®25 is available in the following forms:
  • Granulate
  • Solution

What are the applications for QPAC®25?
Ceramic, metal, or glass powders are used to make high purity technical parts, pastes and inks, and coatings. Non-binder applications include barrier film in plastic processing.

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