Abstract
An oriented film includes an orientated semi-aromatic polyester layer and a thermally conductive filler dispersed in the orientated semi-aromatic polyester layer. The thermally conductive filler is at least 20% wt. of the oriented film.
Claims14
A method comprising:
- dispersing a thermally conductive filler in a thermoplastic material to form a filled thermoplastic material;
- forming a filled thermoplastic layer from the filled thermoplastic material;
- stretching the filled thermoplastic layer to form an oriented filled thermoplastic film, the oriented filled thermoplastic film having a thermal conductivity greater than 0.25 W/(m K).
