QPAC® 40 - Poly (Propylene Carbonate)

Poly (propylene carbonate) is a solid polymer. It is an amorphous, clear, readily processible plastic with long term mechanical stability.

Technical Name Poly (propylene carbonate)

Chemical Formula (C4H₆O₃)_n

Molecular Weight Available From approximately 100,000 to 300,000

Applications

Binder applications for ceramics, metal or glass powders

Pastes and inks

Used to make high purity technical parts

Coatings

Sacrificial structural applications

Decomposable channel former

Pore former

Non-binder applications for barrier film in plastic processing

Typical Physical Properties

Product Delivery Form It is available as a pellet, film, in solution form or as an aqueous emulsion

Benefits

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
