PPSU, PES, PSU Filaments
Sulfone Polymers are part of the PAES (Polyaryl Ether Sulfone) family of polymers which includes PPSU, PES, and PSU. These polymers are high-performance amorphous aromatic polymers that exhibit exceptional thermal, mechanical, and chemical resistance properties.
Based on these exceptional properties, PPSU and PES offer properties that are often superior to Ultem 1010 whereas PSU is often used as a lower-cost alternative to Ultem 9085. Generally, performance in this family of resins follows the trend from highest to lowest PPSU>PES>PSU.
