  • QPAC®40 leaves very little ash residue on decomposition: less than 10 ppm. This results in excellent mechanical and/or electrical properties
  • Components made from QPAC®40 have excellent green strength resulting in final parts with high density and better structure
  • Decomposition takes place at low temperature which is important for thermal sensitive materials and does so more efficiently than other binders
  • Decomposition can take place in a wide range of atmospheres including oxygen, hydrogen, air, nitrogen, argon and vacuum
