Polyarylene sulfide film |
| 摘要 |
It is aimed to provide a polyarylene sulfide film for an acoustic instrument vibrating plate excellent in heat resistance, molding processability, acoustic properties, and also heat moldability. Provided is a polyarylene sulfide film wherein the elongation at break in either a longitudinal direction or a width direction of the film is 100% or more and 250% or less, and the Young's modulus in either a longitudinal direction or a width direction of the film is 1.5 GPa or more and less than 4 GPa. |

1. A polyarylene sulfide film comprising: polyarylene sulfide and polyetherimide resin, wherein the content of the polyetherimide resin is 1 to 40 parts by weight based on 100 parts by weight of the sum content of the polyarylene sulfide and the polyetherimide resin, the elongation at break at 23 degrees Celsius and humidity 65% RH in either a longitudinal direction or a width direction of the film is 100% or more and 250% or less, and the Young's modulus at 23 degrees Celsius and humidity 65% RH in either a longitudinal direction or a width direction of the film is 1.5 GPa or more and less than 4 GPa.
