Overview

Unique Features

Technology Features Include:

• Range of molecular weights (2,500 to 60,000),
• Ability to tailor polymer,
• Ability to produce polyphosphonate-polycarbonate copolymers,
• Completely transparent,
• Inherently flame retardant polymer due to its high limiting oxygen index (LOI),
• High melt flow and melt strength.

Due to the high phosphorus content (10.8%) polyphosphonate homopolymers offer the highest limiting oxygen index (LOI) of all known thermoplastics.
