HOSTAPHAN® polyester films for electrical insulation
Due to its high electrical resistivity, polyester has been used as electrical insulation for many years. Biaxially drawn HOSTAPHAN® film combines this property with high mechanical strength.
Our films offer these advantages:
- high dielectric constant
- high dielectric strength
- dimensional stability
- high temperature resistance
- up to thermal class B (depending on grade)
- high tensile strength
- good elongation to break
- very good chemical and electrical stability
- low fraction of extractables
Typical applications:
- insulation for electrical equipment (motors, transformers)
- flexible printed circuits (FPCs)
- flexible flat cables (FFCs)
- membrane keypads
- wiring and cables
