BIAXIALLY ORIENTED HIGHLY SCRATCH AND ABRASION RESISTANT FILM |
| 摘要 |
<p>A biaxially oriented and heat set film having improved abrasion resistance is described, whose distinguishing characteristics are that it has a density of more than 1.38 g/cm3 and that the following relationship exists between the orientation birefringence ( DELTA n), the reduced specific viscosity (RSV), and the temper peak (Tp) of the film: RSV-¦ DELTA n¦-Tp/250>/=0 with¦ DELTA ¦=¦nMD-nTD¦. In addition, a process for manufacturing the abrasion resistant film is disclosed.</p> |
