POLYESTR FILM FOR CAPACITORS |
| 摘要 |
<p>A film which is a biaxially oriented film comprising polyethylene-2,6-naphthalenedicaboxylate as a principal component, having a thermal strain ratio RMD (150) in the machine direction of the film at a temperature of 150 DEG C is -1.5%</=RMD (150)</=0.0% when the thermal strain ratio RMD (T) in the machine direction of the film at a temperature T DEG C based on the length LMD (t) in the machine direction (MD) of the film at a temperature t DEG C is defined by <DF>RMD (T) = äÄLMD(T) - LMD (35)Ü/LMD (35)ü x 100 (%), </DF> excellent in insulation characteristics without lowering processing characteristics, especially the characteristics during hot-pressing and suitable as a dielectric for capacitors.</p> |
