Document Type and Number:
Japanese Patent JP2019163450
Kind Code:
A
Abstract:
To provide a polyester film excellent in insulation property, thermal conductivity, and mechanical properties, further provide an electric insulation sheet and an adhesive tape excellent in high thermal conductivity and processing property, by using the polyester film, and a wind power generator, an electronic device or the like using the same.SOLUTION: There is provided a film containing polyester as a main constitutional component, and having average L of breaking elongation L1 and L2 ((L1+L2)/2) (%) and thermal diffusivity in thickness direction T(m/s) satisfying following formulae (I) and (II), wherein breaking elongation in a direction a with largest breaking elongation in a film surface is L1 (%) and breaking elongation in a direction b orthogonal to the direction a is L2 (%). T≥1.2×10(I) T≥-1.00×10×L+1.70×10(II).SELECTED DRAWING: None
