Description
Polyimide FEP film is Polyimide film coated with FEP resin on one side or double sides through the sintering process at high temperature, which combines the excellent properties of Polyimide film and FEP resin, high& low temp resistant, radiation resistant, excellent electrical properties, superior dimensional stability and heat sealable properties.
Features
•High temperature electrical insulation
•Cut-through resistant
•High dielectric strength
•High bond strength
Application:
•Wire and cable insulation for downhole pumps and aircraft electrical systems.
•Turn insulation in Motors and Generators.
•Electrical insulation of Flexible Heater.
