PC (Polycarbonate)

Although some structural variations are possible, the most common system is formed by reaction of bispenol A and phosgene. Its applications are almost always those which take advantage of its unique high impact strength. Recently, additional interest has resulted because of its low flammability. Some studies are currently underway to further improve this characteristic.

ADVANTAGES:

• High impact strength
• Low flammability
• Thermoplastic processing methods

DISADVANTAGES AND LIMITATIONS:

• Subject to stress cracking
• Fairly high processing temperatures required (550 F)
• Degrades upon extended residence time in processing equipment
• Solvent resistance is only fair

TYPICAL APPLICATIONS:

Windows, helmets, instrument cases and mechanical goods
