THERMOFORMABLE POLYMERIC SHEETS BASED ON PSEUDO-AMORPHOUS POLYARYLETHER KETONE

Sheets having thicknesses of from 1000 to 10,000 microns which are useful for the production of thermoformed semi-crystalline articles are based on polyaryletherketones having viscosities at 360° C. of at least about 400 Pas at 100 s−1 as measured by parallel plate rheometer. The polyaryletherketone...

Beschreibung
Zusammenfassung:	Sheets having thicknesses of from 1000 to 10,000 microns which are useful for the production of thermoformed semi-crystalline articles are based on polyaryletherketones having viscosities at 360° C. of at least about 400 Pas at 100 s−1 as measured by parallel plate rheometer. The polyaryletherketones are in a pseudo-amorphous state in the thermoformable sheets.
