|
In case of concerns about silicones, Kerafol offers
a ceramics-filled polyurethane film as an alternative material. Besides
good thermal and outstanding electrical properties, these films are
characterized by very good perforation strength. These good physical
properties are achieved with an excellent price-performance ratio.
