BIAXIALLY ORIENTED POLYETHYLENE 2,6-NAPHTHALATE FILM STRIP AND MAGNETIC TAPE USING THE SAME. |
| 摘要 |
<p>A biaxially oriented polyethylene 2,6-naphthalate film strip having a greater Young's modulus in the transverse direction than in the longitudinal direction, a small heat shrinkage ratio in the longitudinal direction and a suitable surface coarseness (Ra & 12 nm). This film has flatness, smoothness and durability applicable to the field of magnetic recording, and is effective for producing magnetic recording media not generating skew distortion.</p> |
