SynTherm® – Insulating Materials SynTherm® P
SynTherm® P is a flexible polyester film based on polyethylene terephthalate. With increasing thickness the film appears to be cloudy or milky white.
With its excellent balance of electrical properties SynTherm® P offers many constructional possibilities for the electrical industry. It is suitable for use in a temperature range from -40 °C to +140 °C short-term.
Application
Polyester film SynTherm® P is suitable for systems up to 130 °C. It is used in motor and generator engineering as wedge and for slot insulation or phase insulation. In transformers, chokes and relays it is often used as core, layer or final insulation.
