PPSF & PSU Filaments

Sulfone Polymers

Polymers in the Sulphone family are amorphous engineering thermoplastics noted for high heat-deflection temperatures, outstanding dimensional stability, and exceptional chemical resistance. These strong, rigid polymers are the only thermoplastics that remain transparent at service temperatures as high as 200°C.  The hydrolytic stability of these resins makes them resistant to water absorption in aqueous acidic and alkaline environments.
