Key Benefits include

QPAC^®PBC, Polybutylene carbonate, is a new polymer/binder with unique properties. It is a very flexible polymer with rubber-like properties that may have beneficial properties in tape casting and other applications where flexibility and good green strength are critical. Since it is a new product its full range of benefits has not been fully identified.
The Tg is approximately 0-20°C.
QPAC^®PBC has been produced in large quantities for evaluation.

Key Benefits Include

• Offered in a wide range of molecular weights
• Excellent adhesion and improved lubricity
• Complete and clean burnout leaving less than 10 ppm ash residue, resulting in superb mechanical and/or electrical properties
• Low-temperature decomposition is excellent for thermally sensitive materials and is more efficient than other binders
• Co-firing in any atmosphere without oxidation
• Outstanding green strength
• Complete and clean burnout at low temperatures
• 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
