PB50000 SERIES

PEI

High-performance polymeric resins based on Imides, Amides and combinations thereof constitute our PB50000 series of materials, of which glass-filled PolyEtherImide (PEI) also known as Ultem® is the most common one and meets the requirements of ASTM D7293.

PB50000 materials are characterized by excellent thermal properties, good chemical resistance, inherent flame retardancy, and exceptional dimensional stability. Even though PB50000 materials preferred processing method is injection and extrusion molding, our compression molding material will also meet your expectations.
