| APTIV XPI™ FILMS A108 |
| APTIV XPI™ Film A108 is an unfilled semi-crystalline film made from VICTREX™ PEEK polymer. The film provides durability and reliability in the most demanding application environments by incorporating all of the outstanding properties of VICTREX™ PEEK ( PolyEtherEtherKetone) polymer in a thin film format. It is typically used as high-voltage e-motor stator insulation, enabling excellent thermal management as well as high electrical performance and maximised copper fill factor, resulting in enhanced e-motor efficiency. |
