THERMOVERFORMBARE POLYARYLETHERKETON-/POLYVINYLFLUORID-SCHICHTSTOFFE. |
摘要 |
A thermoformable laminate comprising (1) a polyaryletherketone sheet having repeating units derived from diphenyl ether having attached to one of the phenyl rings either a 1,4-phenylenedicarbonyl group or a 1,3-phenylenedicarbonyl group, the ratio of 1,4-phenylenedicarbonyl groups to 1,3-phenylenedicarbonyl groups being 70:30 to 0:100, preferably 60:40 to 0:100, especially 60:40 to 50:50, the sheet thickness being about 625-5000 micrometers, and (2) a polyvinyl fluoride film having a thickness of about 12.8 to 204 micrometers can be thermoformed at a temperature of about 160 DEG -200 DEG C., especially 170 DEG -195 DEG C. One important application of such thermoformable sheets is in fabricating three-dimensional panels for aircraft interiors. |
