Questar® brand polyester film provides electrical applications with excellent dielectric strength, good handling and UL recognition in all gauges.

Series	Gauge	Application	Properties
AE	300-1000	Membrane touch switches and spacers	Clear, film surface treated on both sides to provide superior slip and handling qualities. Tough, stable and resistant to chemicals for long service life.
BE	300-1000	Membrane touch switches and spacers	Clear, film surface treated on both sides to provide superior slip and handling qualities. Tough, stable and resistant to chemicals for long service life.
CE	48-500	Electrical insulation, core wrap, power transmission wire and cable	Tensilized, excellent moisture and chemical resistance. Strong and durable. Good dielectrics and handling for core wrap. Chemical inertness, high temperature durability, good components dielectrics and handling characteristics for coating, die cutting, embossing and lamination operations.
DE	500-1400	Electrical insulation in slot liners/wedges and phase insulation for hermetic motors/compressor sealed units, fractional horse power motors and industrial laminations	Excellent dielectric strength, thermal stability and cut-through resistance. Low shrinkage. Good moisture resistance and product uniformity. Used in insulation systems that have been given Class B rating by UL. Delamination resistant. Extremely stiff, mechanically strong.
